Turn on Main Power

Operate "Cooling Mode( )" by setting the desired temperature of the remote controller is less than one of the indoor temperature by 1°C at least.

When in Air Circulation Mode, Compressor/Outdoor Fan is stopped.

Check the sensor for indoor temperature is attached as close as to be effected by the temperature of Heat Exchanger(EVA).

When the sensor circuit for indoor temperature and connector are in bad connection or are not engaged, Compressor/Outdoor Fan is stopped.

• Check the related circuit of RY-FAN.

• 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.
