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 numidity 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.

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 OPERATION control
to OFF( O ) . 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.
THERMOSTAT control set
too warm.
Turn the THERMOSTAT knob clockwise to a cooler
setting.
The air filter is dirty.
Clean the filter at least every 2 weeks.
See the operating instructions 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.
Set the air conditioner's vent to the closed position.
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.
