Post 8000btu lg window a/c cycles on and off prematurely

even when thermostat is set on 60 degrees, 1 year warranty just expired and problems begins, I moved the thermostat out of the bracket and put it in warm water then hot water but no change, the compressor still cycles off after about 5 minutes of nice cold air to just fan for about 5 to 7 minutes then repeats. hoping someone has the answer. please help

I also cleaned filter and condenser, is it possible to bypass the thermostat to keep compressor engaged?

Something else besides the thermostat is probably shutting the compressor down.

Is the thermostat electrical / mechanical ? Or electronic ?

Is there a wiring diagram inside the sheet metal cover ? If so , please take a good clear digital photo and post it . I am wondering if the unit has a low pressure cut off ?

Is anything icing up ?

How old is the unit ?

God bless
Wyr

hi wyr twister: 8k btu lg cycles on and off

unit 14 mo old, thermostat is a two small wires with a plastic/rubber type bulb on the end attached to plastic/nylon bracket in front of condenser, I moved it to outside of grille, no icing up at all, recleaned condenser fins and blow dried w/air gun, dishwashered the filter, repositioned air louvers and now compressor stays engaged 7to 9 minutes before cutting out, at least its a little better. I cant see if fins of the outside coils are dirty behind the fan, looks like new from the outside fin area. thanks to everyone for all insights, paige

I didn't see any model number posted here but some window A/C's have two thermostats or sensors. One controls the cycling and one controls the deicing. There may be a second sensor where you can't see it that senses ice buildup.
