Malfunction Cause
Indoor unit makes noise
•
The sound comes from the fan or compressor relay switching over
(close/open).
•
Air conditioner may make noise in defrost mode or when stopped
due to inverse flow of refrigerant in the unit.
No air blows out of indoor unit
•
When the temperature of the indoor heat exchanger is low
during heating process, the indoor unit will stop air blowing to
prevent blowing of cold air (for 3 minutes).
•
In heating mode, if the outdoor temperature or humidity is high
and the outdoor heat exchanger has more frost, the air
conditioner will activate the auto defrost function and the indoor
unit will stop air blowing for 6-10 minutes.
During defrost, water or steam may flow from the outdoor unit.
Moisture on outlet grill
•
If the air conditioner is left running in high humidity, moisture may
condense on the grill and accumulate there.
