Who's the AC specialist?

...and can tell me why my window AC unit doesnt shutdown at certain temps like they should?
Cheap thermostat? They all do it eventually?

I've heard of them doing this before, but never heard of the cause or the fix?

sorry for not seeing this spending all my time on line looking for a large used jon boat .

Sounds to me it low on gas and just not cooling right ,

the thermostat , it runs across the front of the unit just under the front cover make shore you didn't dislodge it putting the filter back in.

try and put a thermometer near it to see if its getting to temp.
once it has been running try running the temps up to see if it shuts off
if you just installed it is it the right size for the room.

If thats the thermostat, it's not loose and hasnt been moved at all.
It's got the dial 1-10 on the front that reads thermostat.

It's definitely getting to temp. It's just not shutting off when it does. About a week ago I woke up in the morning and it was 66 degrees in here. I stepped out side and it was nasty muggy, thermometer read 77 degrees. I came in and looked at the AC, felt it over and she was bellowing out ice cold air, the dial thermostat was set on 5. I turned it down naturally to get it to go off, and as soon as I did it shut right down. (the compressor)

It's been doing that ever since. It just runs and runs until I turn the thermostat down, no matter where we start from or where we turn it down to.

yea then it does sound like you thought the thermostat .
the thermostat probe is usually is running across the front coil just under the front cover.

Yeah, the thermostat probe is running across the front coil just under the front cover. A pretty little copper tubed running horizontally and snapped into little plastic support clips.

It comes right out of behind the front dial labeled thermostat, by the looks of it.

I would like to know the temp of the air going back into the window unit from the room.
( air going across the filter and stat probe and back into the unit)

if your digital thermostat on the unit is set to 70 and the air going back into the unit across the probe is 68 and the unit is still pumping cold air, then you have a bad stat .

the probe is what tells the stat the room temp

It's not digital though. I'm told the digital ones dont do this either.

But I'm guessing since there's a dial on the front, with the numbers 1 through 10 going around it, that there's some kind of reostat looking thing on the other side.
If I find a coiled up spring type thermostat I'm going to put my foot through it LOL.

Actually ya got me wanting to image Google it now.

I can't imagine the air going into the unit and across that thermostat probe being much different then what my furnace thermostat on the wall reads for temperature, which is about 8 feet from the AC unit. And like I said one morning that read 66 degrees and the AC was still pumping cold air.

Found a pic.
