6.3 Compressor

6.3.1 Basic parameters
Input voltage:230V
Input frequency:25Hz～135Hz
6.3.2 Checking method
1. Power on the Refrigerator, when the cooling fan is working, Check if the compressor is
working If not, remove the electric box cover and check. It should be note that when it is
power-off, the normal compressor will not start in 5 minutes after power-on at the second
time.
2. Use a multi-meter to test the resistance between C & S, M&S and M&C.
Normal range of C&S : About 10.6±5%Ω
Normal range of M&S : About 10.6±5%Ω
Normal range of M&C : About 10.6±5%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.
3. Check the connecting wiring between compressor and main control board behind the
refrigerator back and repair if it is broken.
4、Use a multimeter to measure voltage between pin No.2 and No.4 on CN2 connector of
main control board; then measure frequency between pin pin No.10 and No.11 on CN6
connector. If the voltage equal to electric supply power and there is stabilized frequency
within 25 to 135Hz, it means the main control board is OK, to change the Compressor or
drive borad of Compressor , otherwise change the main control board.
