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

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.

• 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, 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.

• Make sure there are no curtains,
blinds, or furniture blocking the front of
the air conditioner.

• Turn the knob to a higher number.
The highest setting provides
maximum cooling.

• Clean the filter at least every 2 weeks.
See the care and Maintenance
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.
