Air conditioning blowing hot air all the time compressor comes on for about 10 seconds then hot air
For model number CAH18ECR20
Hello Donny, thank you for your question. It could be your unit's refrigerant levels might be low. This usually indicates a refrigerant leak in your system! If that's the case, your air conditioner will continue to run and blow out warm air, trying to reach the temperature you set on your thermostat. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you.

I bought both PC BOARDS and the 3 thermostats even tho I read that cleaning the thermostats will sometimes work. Installed thermostats but still blew hot. Installed push button control module because wife said the buttons don't always work, still blows hot. Slide out A/C from frame about 8 inches, remove 4 screws that hold top cover. All the wires and thermostat connectors must be removed to get main control module out. I took lots of pictures and made my own wiring diagram with notes. The wire connectors look like regular push type, but they do have a release tab that can be pushed with needle nose plyers. Remove screws holding module, and do everything in reverse. Yes, the A/C works properly now. I spent an extra $110 for the thermostats and push button control, but am very happy it works and didn't have to buy a new A/C.
Removed Window Air Conditioner from box purchased New. Plastic Fan Blade was broken when purchased and Appliance store would not repair. Second phase removed cover from the fan area removed and replaced fan blade replaced cover and reinstalled unit into the window case.
