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 mode control to off. 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.
The temp control may not be set correctly.
• Set the desired temperature to a level lower than the current temperature.
The air filter is dirty.
• Clean the filter at least every 2 weeks. See the 'MAINTENANCE (Cleaning
the Air Filter)' 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 fumace floor registers and cold air returns.

cooling the room. Set the Fan Speed High at Fan or Cool mode.
