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
Air conditioner does not
start immediately after a
stop.
An unpleasant odor is
perceived at startup.
You may hear a "gurgling"
noise when the air
conditioner is on.
A thin fog may flow from
the outlet when the air
conditioner is running in
cooling mode.
You may hear a slight crack
when the air conditioner is
started or stopped.
Air conditioner does not
run.
The air conditioner is not
cooling (or heating)
properly.
Remote control cannot
execute control.
Water leaks from indoor
unit.
• To protect the air conditioner when started after a stop, the
microcomputer control delays for 3 minutes before allowing the air
conditioner to start.
• The air conditioner itself is odorless. Any odor is accumulated from the
environment. The solution is to clean the air filter (see Cleaning and
Maintenance).
• If there is still any problem, the air conditioner should be cleaned (Please
contact the Whirlpool Authorized Service Center).
• 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.
• 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.
• This is the sound of friction caused by expansion of the front panel or
other parts due to the change of temperature
• 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? (have it tested by a professional).
• Has the timer function been used correctly?
• Is the temperature setting correctly?
• Is the air intake or outlet of the outdoor unit blocked?
• Is the air filter clogged by dust (see Cleaning and Maintenance)?
• Are all the doors and windows closed
• Is the air flow set to "LOW FAN"?
• Is there another heat source in the room?
• 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.
• Check the remote control for damage.
• High air humidity.
• Condensation overflow.
• Joint of indoor unit drain pipe is loose.
