• Check the indoor temperature sensor is disconnected or not(About 10kΩ / at 25°C).

Check Relay(RY - COMP) for driving compressor.

•When the power(About AC220V/240V) is applied to the connecting wire terminal support transferred to compressor, PWB Assembly is normal.

•Check the circuit related to the relay.
