Possible Causes

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, 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.

• 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.

• See Air Conditioner Freezing Up
