30

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 and the led lamp connector.

B. Unscrew the screws of Led lamp .

You can replace the Led lamp now.

31

REPLACEMENT OF MAIN COMPONENTS

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)

32

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.

33

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 220 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, 220 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.

34

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(220V/50Hz) 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.
