Window AC Help needed!
Hi Everyone,
I have a weird problem for you to diagnose!
I have a Hampton Bay AC (110 v) window AC unit with a fan that continues to run after you turn the power switch to off. It runs for 4-5 minutes after you switch it "off", then the fan turns off. It has never done this before, so I know it isn't proper operation. The lights on the LED display do go out when you switch it to "off".
Also, the pump won't kick on until you turn the thermostat *way* down, to about 60, when it should come on at 73.
It just started doing this last night. I woke up because it was very hot in the room, and the coils were iced over. (Yes, it is clean) I assumed they iced over because it had really cooled off outside, and window AC units will do that if you run it when it is too cold outside.
Any ideas? I've worked on many different electrical systems, power controllers, etc. so I'm not afraid to troubleshoot, but I don't know where to start on this one.
My guess would be that it is a bad thermostat?
I'm going to pull it apart tomorrow. Thanks for the help.

The 110 units can be replaced, rather than repairing them. Its a throw away society, pitch it and get a new one...imo..nambu 0 -
Replace for sure, but quit buying that crap at Home Depot. I have a Whirlpool 110 volt heat/AC window unit on my shop that has been humming right along for 6 years now. Bought it at a local mom & pop appliance store. If it breaks, they will fix it, today, right where it sits. Try that at Home Depot. 0 -

No.. Coils ice over due to low freon level.
If it gets cool enough outside to ice over an AC's condenser. I would just set a box fan in the window..[:o)]0 -
Turn your thermostat to a warmer setting. It sounds like it just froze up. I assume you did take it out and clean it with a waterhose and some good degreaser before using it this season. 0 -
LesWVa is correct. If the coils and filter are clean and it freezes up the unit is low on freon. When the thermal sensor is frozen they will operate in weird fashion. Usually cheaper to replace it than fix it. Kinda like tv's nowadays... when they quit buy a new one. 0
