Troubleshooting and error codes

Problem	Possible Causes	What To Do
Air conditioner does not start	• The air conditioner is unplugged. • The fuse is blown/circuit breaker is tripped. • Power failure.	• 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.
Air conditioner does not cool as it should	• 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.	• 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. • Set the air conditioner's vent to the closed position. • See Air Conditioner Freezing Up below.
Air conditioner freezing up	• Ice blocks the air flow and stops the air conditioner from cooling the room.	• Set the mode control at the Fan Only or the Turbo Cool with the thermostat at 1 or 2.
