Problem
Cause and Solution
Normal Performance
Inspection
The system does not
restart immediately
When the unit is stopped, it will not restart again for 3 minutes to
protect the system.
When electricity is disconnected then reconnected, the
protection circuit will be active for 3 minutes to protect the heat
pump.
Noise is heard
During unit operation or a sudden stop, a swishing or gurgling
noise may be heard. The first 2-3 minutes after the unit has
started is when the noise could be noticeable. This noise is
generated by refigerant flowing in the system.
During unit operation, a cracking noise may be heard. This
noise is sometimes generated by the casing expanding or
shrinking due to temperature changes.
If the airflow is creating a loud noise during unit operation, the
air filter may be too dirty.
Odors
The system circulates odors lingering in the airstream, such as
the smell of furniture, paint, and/or cigarettes.
Mist or steam is blowing
out
During COOL or DRY mode, the indoor unit may blow out mist
or steam. This is due to the sudden cooling of the indoor air.
In DRY mode, fan speed
cannot be changed
In DRY mode, when the room temperature becomes lower than
the set temperature by 2°F, the unit will run intermittently at
LOW speed regardless of FAN setting.
Items to look for
Nonresponsive unit
Is there a power failure?
Is the circuit breaker off?
Is the fuse blown?
Poor Cooling
Is the air filter dirty?
Is there anything blocking the inlet and/or outlet?
Is the temperature set correctly?
Are there any doors or windows open?
Is there any direct sunlight shining through the window during
the cooling operation?
Are there too many heat sources or too many people in the
room during cooling operation?
