Owner’s Manual

12 TROUBLESHOOTING

CAUTION

If any of the following conditions occur, turn off the main power supply switch and immediately contact the dealer :

•Switch operation does not work properly.

•The main power fuse often blows out, or the circuit breaker is often activated.

•A foreign matter or water fall inside the air conditioner.

•When the air conditioner does not operate even after the cause of the protective device activation has been removed.

(The operation lamp and on the remote controller are flashing.)

• Any other unusual conditions are observed.

Before you ask for servicing or repairs, check the following points.

KRecheck

Inoperative

•The main power switch is turned off.

•The circuit breaker is activated to cut off power supply.

•The main power fuse has blown out.

Does not cool well or heat well

•The air inlet and/or outlet of the outdoor unit is blocked.

•Doors or windows are opened.

•The set temperature is too high (In cooling) or low (In heating).

KThese are not failures.

Indoor unit or outdoor unit makes a strange noise.

•When the temperature suddenly changes, the indoor or outdoor unit occasionally makes a strange noise because of expansion/ contraction of parts or change of refrigerant flow.

•Air leaking noise is heard occasionally.

It is generated by the solenoid valve when it is actuated.

•A clattering sound is heard when the power is turned on.

It is generated by the outdoor unit during preparation for operation.

The room air is smelly or a bad odor comes from the air conditioner.

• Smells impregnated in the walls‚ carpets, furniture, clothing, or furs, come out.

Outdoor unit is frosted in heating operation.

Water drains from outdoor unit.

•he outdoor unit is sometimes frosted in heating operation.

In that case, the unit automatically performs defrosting (for 2 to 10 minutes) for increasing the heating efficiency.

•In defrosting operation, both the indoor and outdoor units stop air flow.

•Hiss sound is heard when flow of the refrigerant is changed for defrosting.

•Resultant water of automatic defrosting in heating operation drains from outdoor unit.

A white mist of chilled air or water is generated from the outdoor unit.

• When the indoor unit in cooling operation or the outdoor unit in defrosting operation occasionally steams.

Check these items. If any of these problems still remains, stop the operation, turn off the leakage breaker, and then notifies the dealer of the serial number and details of the error. Never repair any part by yourself as it is dangerous.
