Split system single phase type
2.4.2 Service parts information 2 : Inverter compressor
Check point 1 : Check connection
Check terminal connection of compressor
(Loose or incorrect wiring)
Check point 2 : check winding resistance
Check winding resistance on each terminal
If the resistance value is 0Ω or infinite, replace compressor.
Check point 3 : replace Main PCB
If check point 1 and 2 do not improve the symptom, replace Main PCB.
