i have a Frigidaire Ac & heat window unit(18,500 btu) AC works fine , but the heat no longer turns on , could this be a thermostat issue. What are your thoughts?
For model number LRA18HMU218
Hello Julie, thank you for your question. No heat can be due to the Heater Assembly PS2364340 or even the Power Control Board PS9864896. You will need to test these to see which has a fault. We hope this helps.

A/C blows cold for 10 seconds then heating element comes on and blows hot
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 ... Read more . 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.
