6.3 Compressor

6.3.1 Basic parameters

Input voltage:115~127V
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.
3.Use a multimeter to measure voltage between pin No.2 and No.5 on CN7 connector of
main control board. If the voltage equal to electric supply power, it means the main control
board is OK, to change the Compressor or change the main control board.
6.3.2.1 Compressor checking
Use a multi-meter to test the resistance between C & S, M&S and M&C;
The ambient temperature is 25°C resistance as below:
the range of
Normal range of C&S : About 6.42±7%Ω
Normal range of M&S : About 13.03±7%Ω
Normal range of M&C : About 6.61±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.
