[82] Compressor current protection
[108] Transient over current in IPM module rectier side software
[110] IPM module hardware over current
[123] Transient over current in IPM module rectier side hardware
Check if voltage of power
supply in normal
Check if wire of electric box
is correct and if compressor
wire is xed well
If compressor is normal
(compressor coil resistor
insulation)
If power module is normal
If there are the other
failure recently, such as
112, 113, 117
Solve the failures due to
relative information
Improver power supply circuit
Correct the wiring due to diagram
Replace compressor
Replace power module
Remove the failure
