Step 3 Check magnetic clutch
1, Disconnect the magnetic clutch connector.
2. Check for continuity between the magnetic clutch and a
body ground.
Continuity
Yes
No Action
Adjust magnetic clutch clearance or
check for compressor internal trouble
Check ground wire
If ground wire OK, replace magnetic
clutch
Step 4 Check thermal protector
1. Turn the air conditioner OFF for about 10 minutes.
2. After 10 minutes, check for continuity of the thermal pro-
tector.
