After separating power cord from power
source plug socket, separate connectors
CN10, 70, and 71 of the main PCB, and
check the following items.
1. Measure load terminal and resistance value
between terminals like the following to check
whether there may exist defects of load and
electric wire connection.

Note) COMP parts can be changed by Capacitor, PTC, and Over Load Protector. Therefore, they
are checked by existence of movement.

Measurement after Separation |
After separating connector from the MAIN-PCB,
measure resistance of sensor forging, and judge
fault existence.
1. Freezer Sensor CN 30, measure resistance value between
and
2. Retrigerator Sensor CN30, measure resistance value between
and
3. F-Defrost Sensor CN30, measure resistance value between
and
4. R-Defrost Sensor CN30, measure resistance value between
and
5. Outside Air Sensor CN31, measure resistance value between
and
6. Compare above measurement value with temperature of
location of each sensor. Also compare with sensor resistance
and voltage conversion table about temperature of Ref. 8 of
this manual. And judge whether there is any defect.
At this time, when measuring « 2 or 02, check wire assembly
condition.
