10. Trouble  Shooting

Having trouble?

Air conditioner does not heat or cool well.

When heating operation starts, warm air does not blow from the indoor unit
soon.

During heating mode, the air conditioner stops before the set room tem-
perature is reached.

When the airflow direction is changed, the vanes always move up and down
past the set position before finally stopping at the position.

A flowing water sound or occasional hissing sound is heard.

A cracking or creaking sound is heard.

The room has an unpleasant odor.

A white mist or vapor is emitted from the indoor unit.

Water or vapor is emitted from the outdoor unit.

The operation indicator does not appear in the remote controller display.

” appears in the remote controller display.

When restarting the air conditioner soon after stopping it, it does not oper-
ate even though the ON/OFF button is pressed.

Air conditioner operates without the ON/OFF button being pressed.

Air conditioner stops without the ON/OFF button being pressed.

Remote controller timer operation cannot be set.

“PLEASE WAIT” appears in the remote controller display.

An error code appears in the remote controller display.

Draining water or motor rotation sound is heard.

The fan speed changes in spite of not changing the setting.

Here is the solution. (Unit is operating normally.)

Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)

Check the temperature adjustment and adjust the set temperature.

Make sure that there is plenty of space around the outdoor unit. Is the
indoor unit air intake or outlet blocked?

Has a door or window been left open?

Warm air does not blow until the indoor unit has sufficiently warmed up.

When the outdoor temperature is low and the humidity is high, frost may
form on the outdoor unit. If this occurs, the outdoor unit performs a de-
frosting operation. Normal operation should begin after approximately
10 minutes.

When the airflow direction is changed, the vanes move to the set posi-
tion after detecting the base position.

These sounds can be heard when refrigerant is flowing in the air condi-
tioner or when the refrigerant flow is changing.

These sounds can be heard when parts rub against each due to expan-
sion and contraction from temperature changes.

The indoor unit draws in air that contains gases produced from the walls,
carpeting, and furniture as well as odors trapped in clothing, and then
blows this air back into the room.

If the indoor temperature and the humidity are high, this condition may
occur when operation starts.

During defrosting mode, cool airflow may blow down and appear like a
mist.

During cooling mode, water may form and drip from the cool pipes and
joints.

During heating mode, water may form and drip from the heat exchanger.

During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.

Turn on the power switch. “ ” will appear in the remote controller display.

to provide the dealer with the model name and information that appeared
in the remote controller display.

When cooling operation stops, the drain pump operates and then stops.
Wait approximately 3 minutes.

Not to blow out cold air at the beginning of heating operation, the air
conditioner automatically adjusts the fan speed gradually from lower to
the set speed. It also adjust its fan speed to protect the fan motor when
return air temperature or fan speed excessively rises.
