6-4. Compressor
Drawings attached:
POWER
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)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
belower because of its rotor magnetic force decreasing.
