Is the resistance
normal between compressor
terminals?
Is high pressure and
low pressure normal?
Is the compressor operating?
Even though the compressor is operating
but if there is no response on the
temperature, it is the loading failure.
Replace the PWM valve.
If any one of the resistance of compressor
terminals L1(R)-L2(S), L2(S)-L3(T) and L3(T)-L1(R) is not
normal, it shall be regarded as OLP
trip and then wait until the compressor is
cooled to restart.
If the compressor is under normal operation,
check the causes of OLP trip (amount of
refrigerant, outdoor ventilation structure, etc).
Even though On signal is going to compressor
but if it is not operating, it is the OLP trip due
to the overload, wait to start until the
compressor is cooled.

Test operation (key 4)
- All indoor units
2. Caution
1) The replacement of PWM valve due to the loading failure is the difficult work to abolish the refrigerant in the
1)
system and recharge it, and there is little possibility to appear actually.
So check the above check items carefully.
2) The restart is possible only when the inside temperature of compressor is down lower than
1)
60°C, and therefore it takes about 2-3 hours.
3) If waiting at the state that the power is on during the temperature falling down.
1)
CCH (crank case heater) operates to delay the time to restart. Accordingly, separate the connector to the
1)
CCH (crank case heater) to block the power and reconnect the connector after the completion of final check.
