REPLACEMENT OF MAIN COMPONENTS

7-1. TOP GRILLE PART

A. Unscrew the screw located on both side of top grille (t) with the top grille (t)
fixture。

B. Hold up the top grille (T).

C. Unscrew the screw located on both side of top grille (B).

13

REPLACEMENT OF MAIN COMPONENTS

D. Unscrew the screw located on the cabinet top cover.

E. Pull out the harness display pcb and harness grille door s/w located on back of

top grille (B).

You can replace the door switch, mascot, key, front pcb and front pcb case, etc.

14

REPLACEMENT OF MAIN COMPONENTS

7-2. REPLACE DOOR

7-2-1. A. Disassemble top grille (T) and top grille (B) as described section 7-1.

B. Unscrew the top hinge (

C. Lift the door (

。

R) and pull it out.

R).

D. Replace the door with the new one.

E. Screw the top hinge (

F. Do just like above instructions in replacing the door (L).

L). (this process is opposite to disassemble them.)

15

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.

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)

16

REPLACEMENT OF MAIN COMPONENTS

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

(T-SENSOR IS WHITE COLOR)

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.

17

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 spar ks occurred by other electrical
component’s ON/OFF. ( SNUBBER =Spark killer)
Because of the SNUBBER, 220 voltage is always detected, bu t electrical current in this
case is very little (small Amps.).So, this electrical current is not enough to operate the
evaporator defrost heater.

18

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.
。

7-3-5. REPLACE THE EVAPORATOR FAN MOTOR AND FAN BLADE

A. After lift the evaporator up, unscrew the screw which used in fixing motor

fixture.

B. Disconnect the connectors of harness motor.

Then you can replace the evaporator fan motor and fan blade.

19

7-4. CONTROL BOX PART

- Power relay

- Transformer

- Main PCB

A. Disassemble top grille (t) as described section 7-1 A B.

B. Pull out all connectors connected with control box.

C.Unscrewthescrewslocatedonfrontofevap-housing

E.Pull out the harness main.

主要部件的更换

20

REPLACEMENT OF MAIN COMPONENTS

the Compressor ,Condenser coil Condenser fan motor, ETC. on it.

21

REPLACEMENT OF MAIN COMPONENTS

7-6. REPLACE THE CABINET HEATER AND MULLION HEA TER

A. Disassemble the liner frame cover with the and edge of ‘一’type

screwdriver.(left/right/top/bottom side)
。

B. Disconnect the cabinet heater and pull it out.

You can replace the cabinet heater with the new one.
。

C. Assembl e t h e li n er frame cover.( left/right/top/bottom side)

22

REPLACEMENT OF MAIN COMPONENTS
