Electronic Functional DescriptionAdaptive Defrost OperationDefrost occurs after predetermined length ofcompressor run hours. Compressor run time betweendefrosts changes, or adapts, depending upon recenthistory of defrost lengths (time it takes for defrostterminator to open after defrost heater has beenturned on).• Defrost terminator opens at 55°F (13°C) and

closes at 20°F (-7°C).• Compressor run time between defrosts (CRTD)

will be one of 3 values under normal operation:CRTD 1 (8 hours) or CRTD 2 (12 hours) or CRTD3 (16 hours).If defrost length is low (DT-LO defined as 21minutes) indicating small frost load, CRTD fornext defrost cycle is advanced to next level.If defrost length is high (DI - HI defined as 24minutes) indicating large frost load, CRTD fornext defrost cycle is lowered to next level.If defrost length is between 21 and 24 minutes,CRTD for next defrost cycle remains the same.Initial value at power up CRTD 0 is 4 hours.

• Vacation Mode CRTD equals 96 hours. VacationMode CRTD is interrupted with door openings.Defrost interval will revert back to interval beforeVacation Mode. Three things must occur to reachVacation Mode CRTD:1) Defrost interval must be CRTD 3 (16 hours).2) Both refrigerator and freezer doors must have

remained closed since last defrost cycle.3) Defrost thermostat must have opened in less

than 21 minutes during last defrost cycle.• Six minute dwell time occurs after defrost

terminator opens before compressor andcondenser fan motor will operate. Ten minutedwell time occurs after defrost terminator opensbefore evaporator fan motor will operate. Dwelltime can be bypassed by disconnecting power tothe unit for 30 seconds.

• Conventional defrost can be selected in ProgramMode B.

Freezer Compartment Theory of OperationAs freezer thermistor warms, the resistancedecreases allowing low voltage signal to be sent toelectronic control. Electronic control sends two lowvoltage signals, one to the compressor relay coil (C1)and one to the evaporator fan relay coil (E1).When both relay coils are energized and both relay


contacts are closed, high voltage circuits to evaporatorfan motor and compressor/condenser fan motor arecomplete.As thermistor cools during refrigeration cycle,resistance through thermistor increases blocking lowvoltage signal to electronic control interrupting circuit.

Adaptive Defrost Theory of OperationAfter designated compressor run time, refrigerationcycle is interrupted and electronic control sends a lowvoltage signal to defrost relay coil (def D1).Powering the relay coil closes relay contact (D1)completing high voltage circuit to defrost heaterthrough closed defrost terminator (closes at 15°F).Isolator, which is part of high voltage PC board,recognizes presence of line voltage to defrost heaterand sends low voltage signal to electronic control.

Electronic control keeps count of number of minutesdefrost terminator remains closed (opens at 48°F).Length of time defrost terminator is closed determinesif the next defrost cycle advances by 4 hours ofcompressor run, stays at the same interval, or delaysby 4 hours of compressor run.If defrost terminator does not open before 29 minutes,defrost cycle is automatically terminated by electroniccontrol and refrigeration cycles will resume after 6minute dwell time.

IMPORTANT: When the showroom switch is OFF, theisolator sees line voltage which keeps theelectronic controller from signaling theevaporator fan motor or the compressor relaycoils and also keeps the fresh food andcondensate evaporation fans off.

Component TestingComponent Description Test Procedure

Capacitor Run capacitor connects to relayterminal 3 and L2 side of line.

1. Disconnect power to refrigerator.2. Remove captor cover and disconnect capacitor wires.3. Discharge capacitor by shorting across terminals with a resistor for 1

minute.4. Check resistance across capacitor terminals with ohmmeter set on “X1K”

scale.• Good— needle swings to 0 ohms and slowly moves back to infinity.• Open— needle does not move. Replace capacitor.• Shorted— needle moves to zero and stays. Replace capacitor.• High resistance leak— needle jumps toward 0 and then moves back to

constant high resistance (not infinity).

Capillary tube Capillary is sized in diameter and lengthto feed proper amount of refrigerant toevaporator.

Capillary is soldered to suction line totransfer heat from capillary and addadditional superheat to gas refrigerant incompressor suction line.

Capillary discharges into evaporator.

Restricted or clogged capillary tube must be replaced with tube of same innerdiameter and length.

WARNING!To avoid electrical shock which can cause severe personal injury or death,discharge capacitor through a resistor before handling.

Component TestingComponent Description Test ProceduresCompressor When compressor electrical circuit is

energized, the start winding currentcauses relay to heat. After an amount ofstarting time, start winding circuit turnsoff. Relay will switch off start windingcircuit even though compressor has notstarted (for example, when attempting torestart after momentary powerinterruption).

With “open” relay, compressor will notstart because there is little or no currentto start windings. Overload protection willopen due to high locked rotor run windingcurrent.

With “shorted” relay or capacitor,compressor will start and overloadprotector will quickly open due to highcurrent of combined run and startwindings.

With open or weak capacitor,compressor will start and run as normalbut will consume more energy.

Resistance test1. Disconnect power to unit.2. Discharge capacitor by shorting across terminals with a resistor for 1

minute.3. Remove leads from compressor terminals.4. Set ohmmeter to lowest scale.5. Check for resistance between Terminals “S” and “C” Terminals “R” and “C”

If either compressor winding reads open (infinite or very high resistance) ordead short (0 ohms), replace compressor.

Ground test1. Disconnect power to refrigerator.2. Discharge capacitor by shorting terminals through a resister.3. Remove compressor leads and use an ohmmeter set on highest scale.4. Touch one lead to compressor body (clean point of contact) and the other

probe to each compressor terminal.If a reading is obtained, compressor is grounded and must be replaced.

Operation testIf voltage, capacitor, overload, and motor winding test good, perform the followingtest:1. Disconnect power to refrigerator using power switch.2. Discharge capacitor by shorting capacitor terminals through a resistor.3. Remove leads from compressor terminals.4. Wire a test cord to power switch.5. Place time delayed fuse with UL rating equal to amp rating of motor in test

cord socket. (See Technical Data Sheet)6. Remove overload and relay.7. Connect start, common and run leads of test cord on appropriate terminals

of compressor.8. Attach capacitor leads of test cord together. If capacitor is used, attach

capacitor lead to a known good capacitor of same capacity.

9. Plug test cord into volt-watt meter to determine start and run wattage as wellas check for low voltage which can also be a source of trouble.

10. With power to volt-meter, press start cord switch and release.• If compressor motor starts and draws normal wattage, compressor is

okay and trouble is in capacitor. relay/overload, freezer temperaturecontrol, or elsewhere in system.

• If compressor does not start when direct wired, recover system at highside. After system is recovered, repeat compressor direct wire test. Ifcompressor runs after recovery but would not run when direct wiredbefore recover, a restriction in sealed system is indicated.

• If compressor does not run when wired direct after recover, replacefaulty compressor.

Component Description Test ProceduresCondenser Condenser is of tube and wire

construction located in compressorcompartment.

Condenser is on the high pressuredischarge side of compressor.Condenser function is to transfer heatabsorbed by refrigerant to ambient.

Higher pressure gas is routed tocondenser where, as gas temperature isreduced, gas condenses into a highpressure liquid state. Heat transfer takesplace because discharged gas is at ahigher temperature than air that ispassing over condenser. It is veryimportant that adequate air flow overcondenser is maintained.

Condenser is air cooled by condenserfan motor. If efficiency of heat transferfrom condenser to surrounding air isimpaired, condensing temperaturebecomes higher. High liquid temperaturemeans the liquid will not remove as muchheat during boiling in evaporator asunder normal conditions. This isindicated by high than normal headpressures, long run time, and highwattage.

From compressor refrigerant flows intoserpentine under condensate pan to helpevaporate condensate. and then into pre-condenser loop which helps controlexterior condensation on flange, centermullion, and around freezer door.

From condenser refrigerant flows intocapillary and then to evaporator beforereturning to compressor through suctionline.

Leaks in condenser can usually be detected by using an electronic leak detectoror soap solution. Look for signs of compressor oil when checking for leaks. Acertain amount of compressor oil is circulated with refrigerant.

Leaks in post condenser loop are rare because loop is a one-piece copper tubeexcept for brazed joint visible in machine compartment.

For minute leaks1. Separate condenser from rest of refrigeration system and pressurize

condenser up to a maximum of 9.65 bars (140 PSI) with a refrigerant anddry nitrogen combination.

2. Recheck for leaks.

Remove any lint accumulation, etc. that would restrict normal air movementthrough condenser.

Drier is placed at post condenser loopoutlet and passes liquefied refrigerant tocapillary.

Desiccant (20) 8 x 12 4AXH - 7 M>S> -Grams

Drier must be changed every time the system is opened for testing orcompressor replacement.

NOTE: Drier used in R12 sealed system is not interchangeable with drier used in R134a sealed system. Always replace the drier with Amana part number B2150504.

Before opening refrigeration system, recover HFC134a refrigerant for safedisposal.

Cut drier out of system using the following procedure. Do not unbraze drier.Applying heat to remove drier will drive moisture into the system.1. Score capillary tube close to drier and break.2. Reform inlet tube to drier allowing enough space for large tube cutter.

3. Cut circumference of drier 1 ¼" below condenser inlet tube joint to drier.4. Remove drier.5. Apply heat trap paste on post condenser tubes to protect grommets from

high heat.6. Unbraze remaining part of drier. Remove drier from system.7. Discard drier in safe place. Do not leave drier with customer. If refrigerator is

under warranty, old drier must accompany warranty claim.

WARNING!To avoid severe personal injury or death from sudden eruption of highpressure gases, observe the following:

• Protect against a sudden eruption if high pressures are requiredfor leak checking.

• Do not use high pressure compressed cases in refrigerationsystems without a reliable pressure regulator and pressure reliefvalve in the lines.

CAUTION!To avoid death or severe personal injury, cut drier at correct location. Cuttingdrier at incorrect location will allow desiccant beads to scatter. If spilled,completely clean area of beads.

Component Description Test ProcedureEvaporator Inner volume of evaporator allows

liquefied refrigerant discharged fromcapillary to expand into refrigerant gas.

Expansion cools evaporate tube and fintemperature to approximately -20°Ftransferring heat from freezer section torefrigerant.

Passing through suction line tocompressor, the refrigerant picks upsuperheat (a relationship betweenpressure and temperature that assurescomplete vaporization of liquidrefrigerant) as result of capillary insuction line.

Refrigerant gas is pulled through suctionline by compressor to complete therefrigerant cycle.

Test for leaks in evaporator with electronic leak detector or with soap solution.Compressor oil is circulated with refrigerant; check for oil when checking forleaks.

NOTE: Follow all procedures for recovering R134a refrigerant for safe disposal when opening system.

For minute leaks

1. Separate evaporator from rest of refrigeration system and pressurizeevaporator up to a maximum of 235 PSI with a refrigerant and dry nitrogencombination.

2. Recheck for leaks.Heater, cavity Applied to back of ice and water cavity to

help prevent condensation from formingon face of cavity. Wired in series with hotside of line through auger motor interlockswitch.

Overload/Relay Overload is a temperature and currentsensing device.

Overload opens when high current orhigh compressor temperature is sensed.

After overload opens, reset can requireup to two hours depending on ambienttemperature and residual heat load incompressor.

Relay (See PTC Relay)

1. Disconnect power to the refrigerator.2. Remove relay cover and pull relay off compressor. Pull overload protector

off compressor common terminal.3. With ohmmeter, check the resistance between male terminal and female pin

receptacle terminal which pushes onto compressor common terminal. Atambient room temperature overload protector should have less than 1 ohmresistance. An open overload protector will have infinite resistance.

Relay, PTC When voltage is connected and relay iscool, current passes through relay tostart winding. After a short time, currentheats the resistor in relay and resistancewill rise blocking current flow throughrelay. Start winding remains in the circuitthrough run capacitor.

Solid state relay plugs directly oncompressor start and run terminals.Relay terminals 2 and 3 are connectedwithin relay. Run capacitor is connectedto relay terminal 3. L2 side of the 115VAC power is connected to relay terminal2.

Refrigerant Precautions

WARNING!To avoid personal injury, do not allow refrigerant tocontact eyes or skin.

CAUTION!To avoid risk of property damage, do not use refrigerantother than that shown on unit serial numberidentification plate.

NOTE: All precautionary measures recommended byrefrigerant manufacturers and suppliers applyand should be observed.

Line Piercing ValvesLine piercing valves can be used for diagnosis, butare not suitable for evacuating or charging due toholes pierced in tubing by valves.NOTE: Do not leave line piercing valves on system.

Connection between valve and tubing is nothermetically sealed. Leaks will occur.

Open LinesDuring any processing of refrigeration system, neverleave lines open to atmosphere. Open lines allow watervapor to enter system, making proper evacuation moredifficult.

Dehydrating Sealed Refrigeration SystemMoisture in a refrigerator sealed system exposed toheat generated by the compressor and motor reactschemically with refrigerant and oil in the system andforms corrosive hydrochloric and hydrofluoric acids.These acids contribute to the breakdown of motorwinding insulation and corrosion of compressorworking parts, causing compressor failure.In addition, sludge, a residue of the chemical reaction,coats all surfaces of sealed system, and will eventuallyrestrict refrigerant flow through capillary tube.To dehydrate sealed system, evacuate system (seeparagraph Evacuation).

Leak Testing

DANGER!To prevent serious injury or death from violentexplosions, NEVER use oxygen or acetylene forpressure testing or clean out of refrigeration systems.Free oxygen will explode on contact with oil. Acetylenewill explode spontaneously when put under pressure.

It is important to check sealed system for refrigerantleaks. Undetected leaks can lead to repeated servicecalls and eventually result in system contamination,restrictions, and premature compressor failure.

Refrigerant leaks are best detected with halide orelectronic leak detectors.

Testing Systems Containing a Refrigerant Charge1. Stop the operation (turn refrigerator off).2. Holding leak detector exploring tube as close to

system tubing as possible, check all piping, joints,and fittings.

NOTE: Use soap suds on areas leak detector cannotreach or reliably test.

Testing Systems Containing No Refrigerant Charge1. Connect cylinder of nitrogen, through gauge

manifold, to process tube of compressor and liquidline strainer.

2. Open valves on nitrogen cylinder and gagemanifold. Allow pressure to build within sealedsystem.

3. Check for leaks using soap suds.If a leak is detected in a joint, do not to attempt to repairby applying additional brazing material. Joint must bedisassembled, cleaned and rebrazed. Capture refrigerantcharge (if system is charged), unbraze joint, clean allparts, then rebraze.

If leak is detected in tubing, replace tubing. If leak isdetected in either coil, replace faulty coil.

Service Procedures

Service Procedures


RestrictionsSymptomsRestrictions in sealed system most often occur atcapillary tube or filter drier, but can exist anywhere onliquid side of system.Restrictions reduce refrigerant flow rate and heatremoval rate. Wattage drops because compressor isnot circulating normal amount of refrigerations.Common causes of total restrictions are moisture,poorly soldered joints, or solid contaminants. Moisturefreezes at evaporator inlet end of capillary tube. Solidcontaminants collect in filter drier.If restriction is on low side, suction pressure will be in avacuum and head pressure will be near normalIf restriction is on high side, suction pressure will be ina vacuum and head pressure will be higher thannormal during pump out cycle.Refrigeration occurs on low pressure side of partialrestriction. There will be a temperature difference atthe point of restriction. Frost and/or condensation willbe present in most case at the point of restriction.Also, system requires longer to equalize.Slight or partial restriction can give the samesymptoms as refrigerant shortage including lower thannormal back pressure, head pressure, wattage, andwarmer temperatures.Total restriction on the discharge side of compressorwhen restriction is between compressor and first halfof condenser results in higher than normal headpressure and wattage while low side is being pumpedout.Testing for RestrictionsTo determine if a restriction exists:1. Attach gauge and manifold between suction and

discharge sides of sealed system.2. Turn unit on and allow pressure on each side to

stabilize. Inspect condenser side of system.Tubing on condenser should be warm andtemperature should be equal throughout (nosudden drops at any point along tubing).

• If temperature of condenser tubing is consistentthroughout, go to step 4.

• If temperature of condenser tubing drops suddenlyat any point, tubing is restricted at point oftemperature drop (if restriction is severe, frost mayform at point of restriction and extend down indirection of refrigerant flow in system). Go to step 5.

3. Visually check system for kinks in refrigeration linewhich is causing restriction. Correct kink andrepeat step 2.

4. Turn unit off and time how long it takes high andlow pressure gauges to equalize:

• If pressure equalization takes longer than 10minutes, a restriction exists in the capillary tube ordrier filter. Go to step 5.

• If pressure equalization takes less than 10 minutes,system is not restricted. Check for other possiblecauses of malfunction.

5. Recover refrigerant in sealed system.NOTE: Before opening any refrigeration system,

capture refrigerant in system for safe disposal.

Evacuation and Charging

CAUTION!To avoid risk of fire, sealed refrigeration system mustbe air free. To reduce risk of air contamination, followevacuation procedures exactly.

NOTE: Before opening any refrigeration system, EPAregulations require refrigerant in system to becaptured for safe disposal.

Proper evacuation of sealed refrigeration system is animportant service procedure. Usable life andoperational efficiency greatly depends upon howcompletely air, moisture and other non-condensablesare evacuated from sealed system.Air in sealed system causes high condensingtemperature and pressure, resulting in increasedpower requirements and reduced performance.Moisture i in sealed system chemically reacts withrefrigerant and oil to form corrosive hydrofluoric andhydrochloric acids. These acids attack motor windingsand parts, causing premature breakdown.Before opening system, evaporator coil must be atambient temperature to minimize moisture infiltrationinto system.EvacuationTo evacuate sealed refrigeration system:

1. Connect vacuum pump, vacuum tight manifold setwith high vacuum hoses, thermocouple vacuumgauge and charging cylinder as shown in illustration.Evacuation should be done through I.D. opening oftubes not through line piercing valve.

2. Connect low side line to compressor process tube.3. Connect high side line to drier/process tube.4. Evacuate both simultaneously. With valve “C” and “F”

closed, open all other valves and start vacuum pump.

5. After compound gauge (low side) drops toapproximately 29 inches gauge, open valve “C” tovacuum thermocouple gauge and take micronreading.

NOTE: A high vacuum pump can only produce a goodvacuum if oil in pump is not contaminated.

6. Continue evacuating system until vacuum gaugeregisters 600 microns.

7. At 600 microns, close valve “A” to vacuum pump andallow micron reading in system to balance. Micronlevel will rise.• If in 2 minutes, micron level stabilizes at 1000

microns or below, system is ready to be charged.• If micron level rises above 1000 microns and

stabilizes, open valve “A” and continue evacuating.• If micron reading rises rapidly and does not

stabilize, a leak still exists in system.Close valve “A” to vacuum pump and valve “C” tovacuum gauge. Invert charging cylinder and opencharging cylinder valve “F” to add partial charge forleak checking. With leak detector, check manifoldconnections and system for leaks. After locatingleak, capture refrigerant, repair leak, and begin atstep 1.

ChargingNOTE: Do not use captured or recycled refrigerant in

Amana units. Captured or recycled refrigerantvoids any warranty.

NOTE: Charge system with exact amount of refrigerant.See Technical Sheet or refer to unit serial platefor correct refrigerant charge. Inaccuratelycharged system will cause future problems.

To charge system:

1. Close valves “A” to vacuum pump and “C” to vacuumgauge and “E” to low side manifold gauge.

2. Set scale on dial-a-charge cylinder for correspondingHFC134a pressure reading.

3. Open valve “F” to charging cylinder and let exactamount of refrigerant flow from cylinder into system.Close valve.Low side gauge pressure should rise shortly afteropening charging cylinder valve as system pressureequalizes through capillary tube.If pressure does not equalize, a restriction typicallyexists at capillary/drier braze joint.

4. If pressure equalizes, open valve “E” to low sidemanifold gauge and pinch off high side drier processtube.

5. Start compressor and draw remaining refrigerantfrom charging hoses and manifold into compressorthrough compressor process tube.

6. To check high side, pinch-off drier process tube.Close valve “D” to high side gauge. If high sidepressure rises, repeat high side pinch-off and openvalve “D”. Repeat until high side pinch-off does notleak.

7. Pinch-off compressor process tube and removecharging hose. Braze stub closed while compressor isoperating.

8. Disconnect power. Remove charging hose and brazehigh side drier process tube closed.

9. Recheck for refrigerant leaks.

HFC134a Service InformationHFC134a is alternative refrigerant for CFC12.HFC134a has an ozone depletion potential (ODP)factor of 0.0 and a global warming potential (GWP)factor of 0.27. HFC134a is not flammable and hasacceptable toxicity levels. HFC134a is notinterchangeable with CFC12. There are significantdifferences between HFC134a and CFC12 whichmust be considered when handling and processingrefrigeration system.

Health, Safety, and HandlingHealth, safety and handling considerations forHFC134A are virtually no different than those forCFC12.

To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and dischargecapacitor through a resistor before attempting to service, unless test procedures require power to be connected.Ensure all ground wires are connected before certifying unit as repaired and/or operational.

! WARNING

CAUTION!To minimize risk of contamination which can causeproperty damage, excercise extreme care whenservicing R134a sealed systems.

• No trace of other refrigerants is allowed in HFC134asystems. Chlorinated molecules in other refrigerantssuch as CFC12, etc. will lead to capillary tubeplugging.

• Ester oil is used in HFC134a systems. Do not usemineral oil. HFC134a and mineral oils cannot bemixed. If mineral oils were used in HFC134a systems,lubricant would not return to compressor and wouldcause early compressor failure. If significant amountof oil has been lost from compressor, replace oilrather than adding oil.

• Ester oils used in HFC134a systems are sohydroscopic that by the time an inadequate systemperformance is detected, oil will be saturated withmoisture.

• CFC12 has much higher tolerance to systemprocessing materials, such as drawing compounds,rust inhibitors, and cleaning compounds, thanHFC134a. Such materials are not soluble in HFC134asystems. If materials were to be washed from systemsurfaces by ester oils, they could accumulate andeventually plug capillary tube.

• Care must be taken to minimize moisture fromentering HFC134a system. Do not leave compressoror system open to atmosphere for more than 10minutes. Excessive moisture in HFC134a system willreact with compressor oil and generate acid.

• Compressor must be replaced when performing lowside leak repair.

• Drier filter must always be replaced with service drierfilter, part #B2150504.

Important: Unbrazing drier filter from tubing willdrive moisture from desiccant and into system,causing acids to form. Do not unbraze filter drierfrom tubing. If CFC12 service drier was installedin HFC134A system, drier could overload due toexcessive moisture.

• HFC134a compatible copper tubing, part #R0174075(1/4" O.D. X 18" length) and part #R0174076 (5/16"O.D. X 24" length) must be used when replacingtubing.

• Avoid system contamination by using TowerdrawE610 evaporating oil, part # R0157532, when flaring,swagging, or cutting refrigeration tubing.

RS1200002 Rev. 0 52 May 1998

Replacement Service CompressorHFC134a service compressors will be charged withester oil and pressurized with dry nitrogen. Beforereplacement compressor is installed, pull out 1 rubberplug. A pop from pressure release should be heard. Ifa pop sound is not heard, do not use compressor.Positive pressure in compressor is vital to keepmoisture out of ester oil. Do not leave compressoropen to atmosphere for more than 10 minutes.Compressor Testing Procedures

Refer to Technical Data Sheet “Temperature andRelationship Chart” for operating watts, test points,and temperature relationship test for unit being tested.

• Temperature testing is accomplished by using 3 leadthermocouple temperature tester in specific locations.Test point T-1 is outlet on evaporator coil and T-2 isinlet. Test point T-3 is suction tube temperaturemidway between where armaflex ends and suctionport of compressor (approximately 12 inches fromcompressor).

• Thermocouple tips should be attached securely tospecified locations.

• Do not test during initial pull down. Allow one off cycleor balanced temperature condition to occur beforeproceeding with testing.

• Refrigerator must operate minimum of 20 minutesafter thermocouples are installed.

• Turn control to colder to obtain required on time.• Wattage reading must be recorded in conjunction with

temperature test to confirm proper operation.• Suction and head pressures are listed on

“Temperature and Relationship Chart” Normally theseare not required for diagnosis but used forconfirmation on systems which have been opened.

Service Procedures

To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and dischargecapacitor through a resistor before attempting to service, unless test procedures require power to be connected.Ensure all ground wires are connected before certifying unit as repaired and/or operational.

! WARNING

Brazing

CAUTION!To reduce risk of personal injury or property damage,take necessary precautions against high temperaturesrequired for brazing.

Satisfactory results require cleanliness, experience,and use of proper materials and equipment.Connections to be brazed must be properly sized, freeof rough edges, and clean.Generally accepted brazing materials are:• Copper to copper joints: SIL-FOS (alloy of 15

percent silver, 80 percent copper, and 5 percentphosphorous). Use without flux. Recommendedbrazing temperature is approximately 1400°F. Do notuse for copper to steel connection.

• Copper to steel joints: SILVER SOLDER (alloy of 30percent silver, 38 percent copper, 32 percent zinc).Use with fluoride based flux. Recommended brazingtemperature is approximately 1200°F.

• Steel to steel joints: SILVER SOLDER (see copperto steel joints).

• Brass to copper joints: SILVER SOLDER (seecopper to steel joints).

• Brass to steel joints: SILVER SOLDER (see copperto steel joints).

Checking Electric Heater Assembly1. Disconnect power to unit.2. Ensure heater element is cold, then remove

suspect heater and visually inspect element forobvious damage (breaks, cracks in element, etc.).

3. Attach ohmmeter to element leads. Check forcontinuity (see tech sheet for unit under test).

If element reads open (infinite or very high resistance):4. Check disc type thermostat for continuity (see tech

sheet for open and close values). If open replace.

To avoid death or severe personal injury, never useoxygen, air or acetylene for pressure testing or cleanout of refrigeration system. Use of oxygen, air, oracetylene may result in violent explosion. Oxygenmay explode on contact with oil and acetylene willspontaneously explode when under pressure.

If water valve adjustment screw falls out, put screw inhole and align as shown below.

When small hole is centered in large hole, water filladjustment is 7.5 seconds (normal fill time).

Water ProblemsPoor water quality can cause ice maker to fail orproduce unacceptable cubes. Mineral content or sandcan restrict screen in water fill valve or particle of sandcan keep valve from seating properly.If water valve does not close, the following could occur:• no ice production• small or hollow ice cubes• flooding of ice containerInstall water filter, part #R0183114, to eliminate badtaste, odor, and visible contaminates.Mineral contact can cause lime build up in mold.Wicking of water over mold and poor cube release canoccur. Silicone is applied at upper edges around fill cupand stripper.

Temperature ProblemsFreezer temperatures above normal 0° ± 2°F(-18°±1°C) will slow down ice production. Increase iceproduction by setting freezer to colder setting.Thermostat cycling temperature (1 revolution icemaker) is 17° ± 3°F (-8° ± 1°C). Ice will freeze whenthese temperatures are achieved. Cycling time will beslower if freezer temperature is not cold enough toachieve mode temperatures easily.

Proper ice maker fill is 140 cc±10cc at 7.5 seconds of water fill at an inlet pressureranging from 20 to 120 PSI (1.4 to 8.2 bar).

Wiring HarnessA nonresettable thermal fuse micro device 170°F(78°C) is spliced into red wire of ice maker wiringharness. Fuse will protect freezer plastic liner frommelting if ice maker should overheat. Excessive heatcan cause no ice production. Replacing wiring harnesswill only temporarily solve problem. Replace ice makerthermostats.

To avoid property damage, test for water leaks afterrepair or replacement of water valve. Do not over-tighten connection to household water supply.
