Symptoms
The indoor unit
gives off an
odor.
The air
conditioner
does not emit
warm air.
Possible Causes & Solution
Odors (such as cigarette smoke) may be absorbed into the
indoor unit and discharged with airflow.
• If the smell does not disappear, you need to wash the filter. If
this does not work, contact the service center to clean your heat
exchanger.
When Heating Mode starts, the vane is almost closed, and no
air comes out, even though the outdoor unit is operating.
• This symptom is normal. Please wait until the unit has generated
enough warm air to blow through the indoor unit.
The outdoor unit is in Defrosting Mode.
• In Heating Mode, ice/frost is built up on the coils when the outside
temperature falls. This function removes a layer of frost on the coil,
and it should finish in approximately 15 minutes.
Outside temperature is too low.
• The heating effect may not be sufficient.
