What To Do
- Make sure the air conditioner plug is pushed
completely into the outlet and switched on.
- Check the house fuse/circuit breaker box
and replace the fuse or reset the breaker.
- If power failure occurs, switch off and disconnect/
unplug the power cord. When power is restored,
reconnect (plug in) the power cord, switch on the
power and 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 operating instructions section.
- When the air conditioner is first turned on you
need to allow time for the room to cool down.
The room may have been hot.
Cold air is escaping.
- Check if doors and windows are opened.
- 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.
- Set the fan at MED or HIGH until the ice melts.
