2.2.16 Troubleshooting
These cases are not troubles
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Explanation
Operation does not start soon.
• When ON/OFF button was pressed soon after operation was
stopped.
• When the mode was reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
Hot air does not flow out soon after the start of heating
operation.
• The air conditioner is warming up. You should wait for 1 to 4 minutes.
(The system is designed to start discharging air only after it has reached
a certain temperature.)
The heating operation stops suddenly and a flowing sound
is heard.
• The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 8 minutes.
The outdoor unit emits water or steam.
In HEAT mode
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrost operation.
In COOL or DRY mode
• Moisture in the air condenses into water on the cool surface of
outdoor unit piping and drips.
Mists come out of the indoor unit.
This happens when the air in the room is cooled into mist by the cold air
flow during cooling operation.
The indoor unit gives out odour.
This happens when smells of the room, furniture, or cigarettes are
absorbed into the unit and discharged with the air flow.
(If this happens, we recommend you to have the indoor unit washed by
a technician. Consult the service shop where you bought the air
conditioner.)
The outdoor fan rotates while the air conditioner is not in
operation.
After operation is stopped:
• The outdoor fan continues rotating for another 60 seconds for system
protection.
While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor fan starts
rotating for system protection.
The operation stopped suddenly.
(OPERATION lamp is on)
For system protection, the air conditioner may stop operating on a
sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
