Is the power supply normal? NO

YES

Is the voltage within		NO
the specified range?
	YES
	YES

	YES

Restore it to the

normal state.

Restore it to the

normal state.

Remove any foreign matter

such as dust or dirt.

●Display Conditions

If the inverter’s primary current exceeds the set value for 3 sec- onds, the compressor stops. After a 3 minute delay, it restarts, but when this occurs 5 times within 60 minutes.

Replace the control PCB.

and L3 phases on the 52C

secondary side?

YES

Is there overcurrent	YES
at the compressor?
NO

Outdoor unit control PCB is

faulty. Replace

(The CT input circuit is faulty.)

•Is the power supply voltage proper? (Isn’t it too low?)

•Are the power lines proper? (Aren’t they too thin?)

•Is the overcurrent setting correct? (SW3 setting)

•Is the compressor running with an overload?

•Is the compressor locked?

•During cooling: Is FMo turning?

•During heating: Is FMI turning?

Is the service valve (gas side) fully open?

Is the filter clogged?

•Is there an overcharge?

•Is the installation space for the indoor and outdoor units proper?

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

•Compressor is faulty. Replace

Notes (1) Measure the overcurrent value to make sure.

Also make sure the overcurrent setting set with SW3 and SW4-1 on the outdoor unit control PCB

is not incorrect.
