Cause or check points
When unit is stopped, it won't restart
immediately until 3 minutes have
elapsed to protect the system.
When the electric plug is pulled out
and reinserted, the protection circuit
will work for 3 minutes to protect the
air conditioner.
During unit operation or at stop,
a swishing or gurgling noise may
be heard.At first 2-3 minutes after
unit start, this noise is more noticeable.
(This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking
noise may be heard.This noise is
generated by the casing expanding
or shrinking because of
temperature changes.
Should there be a big noise from
air flow in unit operation, air
filter may be too dirty.
This is because the system
circulates smells from the interior
air such as the smell of furniture,
paint, cigarettes.
During COOL or DRY operation,
indoor unit may blow out mist.
This is due to the sudden cooling
of indoor air.
In DRY mode, when room temperature
becomes lower than temp.
