Question about Heating & Cooling
We have a Model HBLG1400E window unit A/C and it continues to run even when the power switch is turned off. From the sound and due to the fact that there is no air blowing, I assume it is the compressor that is continuing to run. It does turn off if I unplug it but immediately starts again (even though all lights and fan are off) when plugged back in. Weeks ago this happened and we left it off for a day and it started working normally again. Leaving it off for a few hours is not sufficient though.
Thanks in advance for any help you can give me about this.
I have the some problem with a frigidaire model number FAM157S1A. going to try to fix it. will post findings later. pretty sure its a relay problem.

I took the unit apart and found several relays in a slide-out section behind the controls. My guess is that the compressor is controlled by one of these relays and that the contacts may have fused together or may have gotten something on them (e.g. water) which caused a low enough resistance to fool another relay further in the chain. They were soldered in though, so it would not have been easy to test for which one was the culprit. It's not a very safe design. I decided to replace the A/C rather than attempt to find which relay was bad.
