Is the 63H1 operating?

NO

YES

While the 63H1 is operating

1.During Cooling

•Is the outdoor unit fan motor running?

•Is there a short circuit in the outdoor unit?

• Is there enough space for inlet and outlet?

2. During Heating

• Is the indoor unit heat exchanger thermistor separated

from the sensing case?

• Is the filter clogged?

The outdoor unit control PCB

is faulty. (The 63H1 input circuit is faulty.) Replace

3. During Cooling and Heating

• Is the refrigerant overcharge?

• Is the service valve fully open?

[Open phase at L3-phase of 52C primary side]

•Is there a short circuit in the indoor or outdoor units?

•During cooling: Is FMo operating?

Is the service valve fully open?

•During heating: Is FMI operating?

Replace the outdoor unit control PCB.

Does it return to

normal if the power NO supply is reset

(2 of 3 times)?

YES

Replace the outdoor unit control PCB.

Is the service valve fully open?

Is the filter clogged?

•Is liquid flowing back to the compressor?

•Is the compressor making abnormal noises?

It may be malfunction due to transient noise. If there is a noise source nearby, take measures to eliminate it.
