Common
Issues
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 condenser 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.

Common Problems and Solutions

not plugged in completely
The fuse is blown/circuit breaker is
triggered
Power failure.
Air flow is restricted
The THERMOSTAT may not be
set cool enough
The air filter is dirty.
The air conditioner was just

What To Do
• Make sure the plug is completely plugged into
the outlet
• Check the fuse/circuit breaker box and replace
the fuse or reset the breaker
• In the event of a power failure, set the power
control to OFF. When the power is restored,
wait 3 minutes to restart the air conditioner to
prevent the compressor from overloading
• Make sure there are no curtains, blinds,
furniture or other obstacles in front of the air
conditioner
• Turn the knob to a higher setting. The highest
setting provides maximum cooling
• Clean the filter at least every 2 weeks. Refer to
the Care and Maintenance section (p.11) of
the manual.
• After the air conditioner is turned on, you need
to give the air conditioner some time to cool the
room.
• Check for open furnace floor resisters and cold
air returns.
• CLOSE the air conditioner vent
• See "Ice appears on the air conditioner" below
• Ice may block the air flow and obstruct the air
conditioner from properly cooling the room. Set
the fan at MED or HIGH while setting the
thermostat at 1 or 2 until the ice melts.
