Air Recharging in CompressorTest the refrigeration by connecting it electrically beforerefilling operation. It is necessary to ascertain the functionof the motor-compressor and identify the defectsimmediately. If the defects have been found, empty the oldsystem of eventual R-134a residue by breaking off the endof the extension piece at its narrow point. (Figure 1)Replace the filter and any damaged components. Unsolderand pull off the piece remaining inside the service tube andthen attach an extension completely with male Hansen andlast, solder it to the same tube again. (Figure 2)

It is necessary to execute the soldering operation withvalve open so that the fumes caused by oil residue cancome out freely without blowholes between two tubesduring heating the point to be soldered.The extension fitted with the male Hansen is connected tothe female fitting of the vacuum pump tube. (Figure 3)

Air evacuating from the system begins so soon as thepump starts. The refrigeration system must be kept undervacuum until the reading on the low-pressure gaugeindicates vacuum (0 absolute, -1 atm., -760 mm hg) in anycase it is advisable to keep the pump running for about 30minutes. (Figure 3)In case that a considerable leakage occurs and to stop thevacuum pump will be necessary and add a small quantityof Freon to the system, if vacuum should not be obtained(pressure gauge can't fall to 1 atmosphere), start therefrigeration unit and find the leakage with the special leak-finder. When the defective soldering point is visible, re-do itafter opening the extension tube valve and reestablishingthe normal outside pressure inside the group.Because the melted alloy is sucked into the tubes andblock them, the pressure must be rebalanced whenvacuum is in the system in soldering. As soon as the

vacuum operation is over, add the quantity in grams of R-134a to the refrigerant system. Remember that everysystem has an exact quantity of R-134a with a tolerance of±5 grams that can be added. (Figure 4)

Before performing this operation (if the vacuum pump andrefilling cylinder are connected), make sure that the valveplaced between the vacuum pump and refilling tube areclosed to keep the Freon for adding to the system. (Figure 5)

In addition, check the graduated scale on the cylinder forthe quantity of R-134a to be added, for example, if we have750 grams of Freon in the cylinder and must add 165grams to the group, this amount will be reached when R-134a has dropped to 585 grams, remembering that theindicator shows a lower limit of meniscus. Do this afterchoosing the scale corresponding to the gas pressuredifferent scales reported as the same gas pressureindicated by the pressure gauge on the top of the column.To make R-134a flow into the system, open the valveplaced at the base of the cylinder and connected to thefilling tube. The amount of Freon cannot be added to thesystem all at once because it may cause a blocking ofmotor-compressor. Therefore, proceed by adding originalquantity of about 20-30 grams and close the valveimmediately.The pressure rises and the motor-compressor must start,sucking the gas and making the pressure go down again.Regulate the valve again, maintaining the same manneruntil reaching to the quantity of R-134a established for thesystem being charged. When the system is running, thesuction pressure must be stabilized between 0.30 to 0.6atmosphere.

4-1 COMPRESSOR4-1-1 Role

The compressor inhales low temperature and low pressuregas evaporated from Evaporator of the Refrigerator, andcondenses this gas to high temperature and high pressuregas, and then plays delivering role to Condenser.

4-1-2 CompositionThe Compressor is Composed of Compressor Apparatuscompressing gas, Compressor Motor moving CompressorApparatus and Case protecting Compressor Apparatusand Motor. There are PTC-Starter, and Over LoadProtector (OLP) in the Compressor outside. On the otherhand, because the Compressor consists of 1/1000mm processingprecision components and is sealed after producing without dustor humidity, deal and repair with care.

4-1-3 Note to Use(1) Be careful not to allow over-voltage and over-current.(2) No Strike

If applying forcible power or strike (dropping or carelessdealing), poor operation and noise may occur.

(3) Use proper electric components appropriate to theCompressor.

(4) Note to Keep Compressor.If Compressor gets wet in the rain and rust in the pin ofHermetic Terminal, poor operation and poor contactmay cause.

(5) Be careful that dust, humidity, and flux due to weldingdon't inflow in Compressor inside in replacingCompressor. Dust, humidity, and flux due to weldingwhich inflows to Cylinder may cause lock and noise.

4-2 PTC-STARTER

4-2-1 Composition of PTC-Starter(1) PTC (Positive Temperature Coefficient) is no-contact

semiconductor starting device which uses ceramicmaterial and the material consists of BaTiO3.

(2) The higher the temperature is, the higher resistancevalue becomes . These features are used as startingdevice of Motor.

4-2-2 Role of PTC-Starter(1) PTC is attached to Hermetic Compressor used for

Refrigerator, Show Case and starts Motor.(2) Compressor for household refrigerator applies single-

phase induction Motor.For normal operation of single-phase induction motor, inthe starting operation flows in both main coil and sub-coil. After the starting is over, the current is cut off insubcoil. The proper features of PTC play the above allroles. So, PTC is used as a starting device of motor.

4-2-3 PTC-Applied Circuit Diagram According to Starting Method of Motor

4-2-4 Motor Restarting and PTC Cooling(1) For restarting after power off during normal

Compressor Motor operation, plug the power cord after5 min. for pressure balance of Refrigerating Cycle andPTC cooling.

(2) During normal operation of Compressor Motor, PTCelements generate heat continuously. Therefore, if PTC isn't cooled for a while after power off, Motorcan't operate again.

4-2-5 Relation of PTC-Starter and OLP(1) If power off during operation of Compressor and power

on before PTC is cooled, (instant shut-off within 2 min.or reconnect a power plug due to misconnecting), PTC isn't cooled and a resistance value grows. As aresult, current can't flow to the sub-coil and Motor can'toperate and OLP operates by flowing over current inonly main-coil.

(2) While the OLP repeats on and off operation about 3-5times, PTC is cooled and Compressor Motor performsnormal operation.If OLP doesn't operate when PTC is not cooled,Compressor Motor is worn away and causes circuit-short and fire. Therefore, use a proper fixed OLPwithout fail.

4-2-6 Note to Use PTC-Starter(1) Be careful not to allow over-voltage and over-current.(2) No Strike

Don't apply a forcible power or strike.(3) Keep apart from any liquid.

If liquid such as oil or water inflows into PTC, PTC materials it may break due to insulation breakdownof material itself.

(4) Don't change PTC at your convenience.Don't disassemble PTC and mold. If damaging tooutside of PTC-starter, resistance value alters and poorstarting of compressor motor may cause.

(5) Use a properly fixed PTC.

4-3 OLP (OVER LOAD PROTECTOR)4-3-1 Definition of OLP(1) OLP (OVER LOAD PROTECTOR) is attached to

Hermetic Compressor and protects Motor by cutting offcurrent in Compressor Motor by Bimetal in the OLP incase of over-rising temperature.

(2) When over-voltage flows to Compressor motor, Bimetalworks by heating the heater inside OLP, and OLP protects Motor by cutting off current whichflows to Compressor Motor.

4-3-2 Role of OLP(1) OLP is attached to Hermetic Compressor used to

Refrigerator and Show Case and prevents Motor Coilfrom being started in the Compressor.

General Control of Refrigerating Cycle

The following description is basically for GR-262/GR-292. For the other models, refer to the diagram of the entire PCBcircuit.

7-1 FUNCTION

7-1-1 FUNCTION1. When the appliance is plugged in, it is set to ‘Medium’. Each time the button is pushed, it is set to

‘Medium’→‘Medium/High’→‘High’→‘Low’→‘Medium/Low’→‘Medium’ in order.

2. When the power is initially applied or restored after a power failure, it is automatically set to ‘Medium’.

7-1-2 DEFROSTING1. The defrosting is performed each time when the total running time of the compressor reaches 7 hours.

2. After the power is turned on (or restored after a power failure), the defrosting starts when the total running time of thecompressor reaches 4 hours.

3. When the temperature of the defrosting sensor reaches 13 °C or above, the defrosting stops. If the temperature does notreach 13 °C in 2 hours after the defrosting starts, the defrosting error code is displayed. (Refer to 7-1-4 Error Diagnostic Mode.)

4. With the defective defrosting sensor (cut or short-circuited wire), the defrosting will not be performed.

7-1-3 SEQUENTIAL OPERATION OF ELECTRIC COMPONENTSThe electric components, such as the comp, defrosting heater, and cooling fan, start sequentially to avoid the noise anddamage to the part, which may result from the simultaneous start of various components on turning the power on or afterthe completion of a test.

Condition of Operation Operating Sequence

If the temp of the defrosting sensor is 25 °C or above(For the initial use after the purchase or grounding)

If the temp of the defrosting sensor is below 25 °C(After a power failure or SVC)

7-1-4 ERROR DIAGNOSTIC MODE1. The error diagnostic mode allows the SVC when a fault that may affect the performance of the product occurs while

operating the product.

2. Even if the function control button is pushed when an error occurs, the function will not be performed.

3. When the error is cleared while the error code is displayed due to a fault, the appliance returns to the normal condition(Reset).

4. The error code is displayed by the refrigerator temp indication LED on the display of the refrigerator while the remainingLEDs are off.

7-2 PCB FUNCTION

7-2-1 POWER CIRCUIT

The secondary part of the TRANS is composed of the power supply for the display and relay drive (12Vdc) and that for theMICOM and IC (5Vdc).

The voltage for each part is as follows.

VA1 is a part for preventing the over voltage and noise. When 385V or higher power is applied, the inside elements areshort-circuited and broken, resulting in the blowout of the fuse in order to protect the elements of the secondary part of theTRANS.

PART VA 1 CE 2 CE3

VOLTAGE 220 Vac 12 Vdc 5 Vdc

7-2-2 OSCILLATION CIRCUIT

This circuit is to generate the base clock for calculating time and the synchro clock for transmitting data from and to theinside logic elements of the IC1(MICOM). Be sure to use the authentic parts since the calculating time by the IC1 may bechanged or it will not work if the OSC1 SPEC is changed.

7-2-3 RESET CIRCUIT

The RESET circuit is for allowing all the functions to start at the initial conditions by initializing various parts including theRAM inside the MICOM (IC1) when the power is initially supplied or the power supply to the MICOM is restored after amomentary power failure. For the initial 10ms of power supply, ‘LOW’ voltage is applied to the MICOM RESET terminal.During a normal operation, 5V is applied to the RESET terminal. (If a trouble occurs in the RESET IC, the MICOM will notwork.)
