Problem Possible Solution
Indoor unit fan stops
during heating
-
The air conditioner is deicing and it takes
10 minutes at most. (It freezes when the
outdoor temperature is low and humidity
is high.) It automatically resumes operation
about 10 minutes later
Cracking sounds can be heard - The friction sounds are caused by expansion
and contraction of front grille resulting
from temperature changes
You can hear the sound of
running water
- It is the sound of owing refrigerant inside
the air conditioner.
- Sound of accumulated owing water on
the Heat-exchanger.
- Sound of frost melting on the heat
exchanger
Indoor unit makes “bush” and/or
“click” sound
- Click sound is made by the switching of
the fan or compressor. The“bush” sound is
made by the switch of refrigerant owing
inside the air conditioner
When the unit is set to directional
swinging at low angle on Cool
mode: the deector will/may
auto swing to its maximum angle
for 3 minutes and then resume to
swing at the low angle
- This function prevents the production of
condensed water. It is a normal operation
for the air conditioner
Indoor unit gives odour - Air conditioner may have absorbed odours
from wall, carpet, furniture and in turn
blows it out
- Follow the Cleaning and Maintenance
procedures
Outdoor unit leaks water -
During cooling, connecting pipe or pipe
connector will cause the moisture content
condensation due to the low temperature.
- During heating or defrosting, melting
water and water vapor will run out.
- During heating, water on heat exchanger
will drop
