- Measure the resistance at each point except point C
- Dead short check: measure the resistance between power line in compressor and earth ground in refrigerator (Inf. Ohm)

Caution : Turn off power during check C

* Because of ambient temperature or operating

situations, the values shown can have a slight
deviation.

11-3 Check C

C1. Harness Connection Check
C2. Capacitor Specifications
C3. Compressor Check

- Step 1. Power off. Step 2. Check capacitor spec. (table1). Step3. Check resistance of point A

Step 4. Check wire harness (INF ohm). Step 5. Check resistance at point B. Step 6. Point D.
