Issue
Possible Causes
Unit does not turn on when pressing
ON/OFF button
The Unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of
being turned off.
The unit changes from COOL/HEAT
mode to FAN mode
The unit may change its setting to prevent frost from forming on the
unit. Once the temperature increases, the unit will start operating in
the previously selected mode again.
The set temperature has been reached, at which point the unit turns
off the compressor. The unit will continue operating when the tempe-
rature fluctuates again.
The indoor unit emits white mist
In humid regions, a large temperature difference between the room’s
air and the conditioned air can cause white mist.
Both the indoor and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may
be emitted due to moisture generated from the defrosting process.
The indoor unit makes noises
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode
due to expansion and contraction of the unit’s plastic parts.
Both the indoor unit and outdoor
unit make noises
Low hissing sound during operation: This is normal and is caused by
refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or
is defrosting: This noise is normal and is caused by the refrigerant gas
stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and me-
tal parts caused by temperature changes during operation can cause
squeaking noises.
The outdoor unit makes noises
The unit will make different sounds based on its current operating
mode.
Dust is emitted from either the indoor
or outdoor unit
The unit may accumulate dust during extended periods of non-use,
which will be emitted when the unit is turned on. This can be mitiga-
ted by covering the unit during long periods of inactivity.
The unit emits a bad odor
The unit may absorb odors from the environment (such as furniture,
cooking, cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the outdoor unit does not
operate
During operation, the fan speed is controlled to optimize product
operation.
Operation is erratic, unpredictable, or
unit is unresponsive
lnterference from cell phone towers and remote boosters may cause
the unit to malfunction.
In this case, try the following:
•
Disconnect the power, then reconnect.
•
Press ON/OFF button on remote control to restart operation.
NOTE:
lf problem persists, contact a local dealer or your nearest customer service center. Provide them with
a detailed description of the unit malfunction as well as your model number.
