Test in resistance.
TOOL: Multimeter.
Test the resistance of the winding. The compressor is fault if the resistance of
winding 0(short circuit)or∞
（
open circuit
）
Familiar error:
1)
Compressor motor lock.
2)
Discharge pressure value approaches static pressure value .
3)
Compressor motor winding abnormality.
Notes
：
1)
Don’t put a compressor on its side or turn over.
2)
Please assembly the compressor in your air conditioner rapidly after removing
the plugs. Don’t place the comp. In air for along time.
3)
Avoiding compressor running in reverse caused by connecting electrical wire
incorrectly.
4)
Warning! In case AC voltage is impressed to compressor, the compressor
performance will below because of its rotor magnetic force decreasing.
