Yes
Turn off the power and change the location of
the temperature sensor or replace it.
No
Are the position and measuring value of the
temperature sensor normal?
Continue
Check the connection status of compressor.
No
Is compressor wire connected properly to the
compressor?
Yes
1. Replace the compressor : If the resistance
value between phases of the compressor is
different.

3. Replace the compressor : When loud
abnormal n
oise generates (metal cutting or
grinding noise), or severe vibration.
No
Check the compressor.
1. Are all the resistance values
between phases matched?
(U ļ V, U ļ W, V ļ W)
2. Is compressor wiring normal? (disconnection,
wrong connection)
3. Is there any abnormal noise
from
compressor rotation?
Yes
Replace the compressor.
No
Yes
Is there a reading of MegaΩ of resistance
between compressor body and chassis?
