Symptoms
The air conditioner
does not emit cool
air.
The air conditioner
does not emit warm
air.
Possible Causes & Solution
Air is not circulating properly.
• Make sure that there are no curtains, blinds, or pieces of furniture blocking the
front of the air conditioner.
The air filter is dirty.
• Clean the air filter once every 2 weeks.
• Refer to the air filter cleaning instructions.
The room temperature is too high.
• In summer, cooling the indoor air fully may take some time. In this case, select
the Jet Mode to cool the indoor air quickly.
Cold air is escaping from the room.
• Make sure that no cold air is escaping through the ventilation points in the
room.
The desired temperature is higher than the current temperature.
• Set the desired temperature to a level lower than the current temperature.
There is a heating source nearby.
• Avoid using heat generators like electric ovens or gas burners while the air
conditioner is in operation.
Fan Mode is selected.
• During Fan Mode, air blows from the air conditioner without cooling or heating
the indoor air.
• Switch the operation mode to cooling operation.
Outside temperature is too high.
• The cooling effect may not be sufficient.
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.
