2-26. E: 95. Compressor motor control error (Outdoor unit)
Indicator
→ired remote
controller
Error code E: 95
Detective actuator Outdoor unit
Main PCB 1. →hen running the compressor, if the detected rotor
location is out of phase with actual rotor location
more than 90°, the compressor stops.
2. After the compressor restarts, if the same operation
is repeated within 40 seconds, the compressor
stops again.
3. If 1. and 2. repeats 5 times, the compressor stops
permanently.
Compressor
Forecast of cause
Defective connection of electric components
Main PCB failure
Compressor failure
Check point 1. Check Noise from Compressor
Turn on Power and check operation noise.
If an abnormal noise show, replace compres-
sor.
Check point 2. Check connection of around the compressor components
For compressor terminal, main PCB
• Check if connector is removed.
• Check erroneous connection.
• Check if cable is open. (Refer to inverter compressor in "Service parts information" on page 03-
44.)
Upon correcting the removed connector or mis-wiring, reset the power.
Check point 3. Replace main PCB
If Check point 1, 2 do not improve the symptom, change main PCB.
Check point 4. Replace compressor
If Check point 3 do not improve the symptom, change compressor.
