6.3 Compressor
6.3.1 Basic parameters
Input voltage:115V
Input frequency:60Hz
6.3.2 Checking method
1.Compressor will start 10 seconds after power-on, if it starts unsuccessfully, remove the
electric box cover and check.
2.Check the connecting wiring between compressor and main control board and repair if it is
broken.

6.3.2.1 Compressor checking
Use a multi-meter to test the resistance between C & M, C&S and M&S :
The ambient temperature is 20
℃，
the range as below
：
Normal range of C&M : About 6.83±7%Ω
Normal range of C&S : About 6.23±7%Ω
Normal range of M&S : About 13.1±7%Ω
●
If the test result is not in this range then it means the inner coil has some problem and the
compressor cannot work properly.
