→ired remote
Indicator
controller
Detective actuator Outdoor unit
Forecast of cause
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
53.)
Upon correcting the removed connector or mis-wiring, reset the power.
Check point 3. Replace inverter PCB
If Check point 1, 2 do not improve the symptom, change inverter PCB.
Check point 4. Replace main PCB
If Check point 3 do not improve the symptom, change main PCB.
