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 trouble: 1) Compressor motor lock. 2）Discharg
e 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 yo
ur air conditioner rapidly after removing
the plugs. Don’t place the comp. In air for a long time.
3) Avoiding compressor running in r
everse caused by connecting electrical wire
incorrectly.
4) Warning! In case AC voltage is impr
essed to compressor, the compressor
performance will be lowered because of its rotor magnetic force decreasing.
