Power supply check:
Measure the power supply at L.N.
(It is normal if it is AC 220-240V)
Noise filter check:
There should be continuity.
There should be no shorts between phase
Must be conductive.
When fuse is blown,
replace it or check wiring.
LED2(Red) check:
1~5 time flash : Refer to page 121
No anomaly like breakage,
swell, etc. allowed.
Voltage between terminals
When stopped : 280V ~ 373V
During operation : 380V ~ 390V
Fuse check:
There should be continuity.
If faulty, replace the control PCB
When the outdoor unit fan
motor is anomalous:
(Refer to page 186)
