The air conditioner does not start operation
immediately after it is turned on.

To reduce excessive load in a restart, the air conditioner does not operate for three minutes when the ON switch is pressed immediately after it is shut down or when the operation mode (setting) is changed using the remote controller.

The air conditioner produces a water flowing sound.

The water flowing sound is produced by the refrigerant that flows inside the air conditioner. This sound is more prone to generation when the defrost operation is activated in a heating operation.

The air conditioner produces an air releasing sound.

The air releasing sound is caused by a change of the refrigerant flow direction. This sound is generated when the air conditioner stops operating or the defrosting operation is activated in a heating operation.

The air condition produces a crackling sound.

Plastic parts such as the front panel produces a crackling sound when they expand or contract slightly due to temperature change.

The amount of drained water is large (as compared to the amount
discharged in the previous year or the day before).

The amount of drained water varies depending on room temperature and humidity. A large amount of drained water does not denote a malfunction.

The air conditioner does not operate (Operation lamp is not lit).

Check the following.

• Make sure the circuit breaker is not turned off and the fuse is not blown.
• Make sure the power cord plug is connected securely to the service outlet.
• Make sure there is no power outage.
• Make sure the remote controller has new batteries.
• Make sure the timer is not programmed mistakenly.

The air conditioner stops operating (Operation lamp blinks).

• Check to see if the air filters are clean.
• Also make sure the air inlets and outlets of the indoor and outdoor units are not blocked.

The indoor unit produces a mist.

The cold air blow out during a cooling operation reduces the temperature of the room air and sometimes generates a mist.

The air conditioner stops operation (Operation lamp remains lit).

When power supply voltage fluctuates largely, the air conditioner may stop operating to protect the equipment. When power supply returns to a normal condition, the air conditioner resumes operation after three minutes.

The air conditioner stops in the middle of operation
(ON timer in operation).

When the ON timer is set, the air conditioner may start as early as one hour before the set time in order to bring the room temperature close to the temperature set with the remote controller. If the remote controller is operated (except ON/OFF operation) during this time period, the air conditioner enters the stop mode. When this happens, turn on the air conditioner using the remote controller, and set the timer again.
