Troubleshooting Tips
Save time and money! Review the chart below first and
you may not need to call for service.
Normal Operation
• You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy
days or when the humidity is high. This design feature helps remove moisture and improve efficiency.
• You may hear the thermostat click when the compressor cycles on and off.
• Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from
the outdoor side of the unit.
• The fan may run even when the compressor does not.

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