NO

Try to lower setting temperature by thermostat knob cooler.

HEAT mode (Only for heat pump model)

Is room temperature too high ?

NO

Try to raise setting temperature by thermostat knob warmer.

B. Check compressor and electrical parts.

•Check compressor motor capacitor.

•Measure resistance of compressor motor winding.

(Only for 115V models)

• Check PTC thermistor.

Overload relay is working. (OLR)

YES

Temperature of compressor is abnormally high.

YES

Refrigerant gas shortage.

YES

Charge refrigerant gas (R22).

NO

Rotor may be locked up.

Cooling & electric heating models

●If the unit is turned off during cooling, DO NOT restart it immediately, as this can damage it. Wait at least 3 minutes or so before starting it again.

Heat pump model

●The compressor does not start up immediately even when the MODE selector switch is set to COOL or HEAT (It starts operating in about 3 minutes).

●This is because rough 3-minute timer is built into the heat pump model in order to protect the compressor. When operation is started up or restarted, the fan operation begins immediately but the compressor starts operating after about 3-minute lag.
