Description of proplem
Temperature sensor built into indoor IPM (TH)
has been open/short-circuited.
Inverter current (Idc) detection circuit detects
overcurrent.
Compressor lockup is detected
Abnormal current is detected while inverter
compressor is turned off.
High-pressure SW is activated.
Temperature sensor built into IPM (TH) detects
overheating or has been short-circuited.
Outdoor fan IPDU detects trouble.
Short-circuit protection for compressor motor
driver circuit components is activated (momentary
overcurrent).
Compressor motor position detection trouble is
detected.
