Checking the Compressor
Use a multi-meter to test the resistance between C & M, C&S and S&M :
Normal range of C&M : About 10-21Ω
Normal range of C&S : About 10-27Ω
Normal range of S&M : About 20-50Ω
If the test result is not in this range then it means the inner coil has some problem and the compressor can not
work properly.
