EAEM
SPLIT-TYPE ROOM AIR CONDITIONER
Issue
Possible Causes
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 metal 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
mitigated 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
Interference 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
If 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.
