Common Problems and Solutions
Before calling for service
If you have problems with your air conditioner, read the following information and try to solve
the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.
Air conditioner does not operate
1. Ensure that the air conditioner is plugged into a proper outlet.
2. Check the fuse or circuit breaker.
3. Check whether the voltage is unusually high or low.
Air does not feel cold enough on the cooling setting
1. Ensure that the temperature settings are correct.
2. Check to see if the air filter is clogged with dust. If so, replace the filter.
3. Ensure that the air flow from the outside is not obstructed and that there is a clearance of
over 20" between the back of the air conditioner and the wall or fence behind it.
4. Close all doors and windows and check for any source of heat in the room.
Before calling for service, please review the following list of common problems and
solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the fan on rainy days
or in highly humid conditions. This feature is designed to help remove moisture in the air
and improve cooling efficiency.
• You hear the thermostat click. This is caused by the compressor cycle starting and
stopping.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in
highly humid conditions or on rainy days. This water overflows and drips from the rear of
the unit.
• You hear the fan running while the compressor is silent. This is a normal operational
feature.

Possible Causes
What To Do
The air conditioner is
unplugged.
• Make sure the air conditioner plug is
pushed completely into the outlet.
The fuse is blown/circuit
breaker is tripped.
• Check the house fuse/circuit breaker
box and replace the fuse or reset the
breaker.
Power failure.
• If power failure occurs, turn the mode
control to Off.
When power is restored, wait 3
minutes to restart the air conditioner
to prevent tripping of the compressor
overload.
Airflow is restricted.
• Make sure there are no curtains,
blinds, or furniture blocking the front of
the air conditioner.
The thermostat may not be
set high enough.
• Turn the knob to a higher number.
The highest setting provides
maximum cooling.
The air filter is dirty.
• Clean the filter at least every 2 weeks.
See the care and Maintenance
section.
The room may have been
hot.
• When the air conditioner is first turned
on, you need to allow time for the
room to cool down.
Cold air is escaping.
• Check for open furnace floor registers
and cold air returns.
Cooling coils have iced up.
• See Air Conditioner Freezing Up
below.
Ice blocks the air flow and
stops the air conditioner from
cooling the room.
• Set the mode control at High Fan or
High Cool with thermostat at 1 or 2.
