31

REPLACEMENT OF MAIN COMPONENTS

D. Lift the door

(T) (L) and pull it out.

E. Unscrew the middle hinge (L).

F. Lift the door (U) (L) and pull it out.

32

REPLACEMENT OF MAIN COMPONENTS

Then you can replace new doors and assemble them, those processes are opposite to

disassemble them.

G. Do just like above instructions in replacing the door (T)(R) and the door (U)(R).

33

REPLACEMENT OF MAIN COMPONENTS

7-3. REFRIGERATION COMPARTMENT’S PART

- Duct and Lamp

- T-sensor and D-sensor

- Evaporator coil and F-sensor

- Defrost heater (freezer only)

- Evaporator fan motor and fan blade

7-3-1. REPLACE DUCT AND LAMP

A.Disassemble the Duct.

B. Unscrew the screws of lamp cover.

C. Pull out the lamp socket and lamp

34

REPLACEMENT OF MAIN COMPONENTS

You can replace the lamp now.

7-3-2. REPLACE T SENSOR AND D SENSOR (T-SENSOR IS WHITE COLOR, F-SENSOR IS ORANGE

AND D-SENSOR IS BLUE)

A.Disassemble the Duct as in 7-3-1

B. Disconnect the connector and pull out the D-sensor from the evap. replace the

new one.

(D-SENSOR IS BLUE)

C. Take off the T-sensor from the evap. replace the new one.

(T-SENSOR IS WHITE COLOR)

35

REPLACEMENT OF MAIN COMPONENTS

7-3-3. REPLACE THE EVAPORATOR COIL AND F-SENSER

A. Welding off the connection suction pipe(A) and (B).

B. Unscrew the screw located on back side of evap. housing.

C. Take off the evaporator.

36

REPLACEMENT OF MAIN COMPONENTS

D. Disconnect the connector and Unscrew the screws located on sensor cover and pull out the F-sensor from the evap.sensor guide, replace the new one.

7-3-4. REPLACE THE DEFROST HEATER (FREEZER ONLY)

A. After lift the evaporator up, disconnect the connectors with harness defrost

heater and disassemble the defrost fixture spring and split the hooks of the evap..

B. Replace the new defrost heater and fix it with heater fix spring. Connect the

connectors.

*NOTE Why is always 115 voltage detected between connectors of the evaporator defrost

heater in the main harness?

The SNUBBER (located Main PCB) holds two AC power lines simultaneously. The SNUBBER prevents Main PCB malfunction from sparks occurred by other electrical component’s ON/OFF. ( SNUBBER =Spark killer) Because of the SNUBBER, 115 voltage is always detected, but electrical current in this case is very little (small Amps.).So, this electrical current is not enough to operate the evaporator defrost heater.

37

REPLACEMENT OF MAIN COMPONENTS

How to measure the Amps. of the evaporator defrost heater

Disconnect the connectors of the evaporator defrost heater. Then , prepare the additional Power Source(115V/60Hz) and the Amp. Meter. Connect the connectors of the evaporator defrost heater to the additional power source and read amp. Value from the Amp. Meter.
