Check if voltage of power supply is normal
Improve power supply circuit
Replace the wires
Replace the compressor
Check the wires among U, V,
W of compressor are normal
If compressor is normal
(compressor coil resistor, insulation)
Compressor load too much,
check the reason
Check the temperature sensor
characteristic is correct
Check the radiator is blocked
If screw of module is fixed well, and if
radiating silica gel is daubed enough and
evenly, if there is no dirt on radiator
Improve the running
environment of outdoor unit
Fix it well and daub gel
again, clean the radiator
