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.
4. INDUCTANCE
Familiar error:
1
）
Sound abnormality
2

6. FUSE
Checking continuity of fuse on PCB ASS’Y.
1) Remove the PCB ASS’Y from the electrical component box. Then pull out the fuse from the
PCB ASS’Y (Fig.1)
