TROUBLESHOOTING
Warning:
Do not attempt to repair the air conditioner yourself. Incorrect repairs may cause electrocution or fire,
so please contact the Whirlpool Authorized Service Center nearest you for professional repairs.
The following checks may save your time and costs.
Malfunction
Cause
Air conditioner does not start
immediatly after a stop.
• To protect the air conditioner when started after a stop, the
microcomputer control delays for 3 minutes before allowing the
air conditioner to start.
An unpleasant odor is perceived
at startup
• The air conditioner itself is odorless. Any odor is accumulated
from the environment. The solution is to clean the air filter (see
page 42).
• If there is still any problem, the air conditioner should be cleaned
(Please contact the Whirlpool Authorized Service Center).
You may hear a “gurgling” noise
when the air conditioner is on
• When the air conditioner is started, or the compressor starts or
stops while running, or the air conditioner is stopped, you may
hear a gurgling noise that is the refrigerant flowing back and is not
a malfunction.
A thin fog may flow from the
outlet when the air conditioner is
running in cooling mode.
• This may occur when the indoor temperature and humidity are
high. This is because the indoor air is cooled quickly.
• After a short time, the fog will disappear as the indoor
temperature and humidity decrease
You may hear a slight crack when
the air conditioner is started or
stopped
• This is the sound of friction caused by expansion of the front panel
or other parts due to the change of temperature
Air conditioner does not run.
• Is there a power failure?
• Is the power plug loose in the socket?
• Has the circuit protection device been tripped?
• Is the voltage too high or too low? (see page 46 - have it tested by
a professional).
• Has the timer function been used correctly? (see page 39)
The air conditioner is not cooling
(or heating) properly
• Is the temperature setting correct? (see page 38)
• Is the air intake or outlet of the outdoor unit blocked?
• Is the air filter clogged by dust? (see page 42)
• Are all the doors and windows closed
• Is the air flow set to “LOW FAN”?
• Is there another heat source in the room?
Remote control cannot execute
control
• The remote control sometimes cannot execute control if the air
conditioner is subject to abnormal interference or frequent switch
of functions. To resume normal operation, switch off and on again
properly.
• Is the remote control in range and not blocked by any obstacles?
• Check the battery in the remote control. If low, replace the
battery. (see Page 41)
• Check the remote control for damage
Water leaks from indoor unit
• High air humidity
• Condensation overflow
• Joint of indoor unit drain pipe is loose
Water leaks from outdoor unit
• In cooling mode, water may condense on pipe or pipe joint due to
cooling.
• Defrost water flows out in heating or defrost (auto defrost) mode
• In cooling mode, water from heat exchanger may leak
