The replacement thermostat arrived after the 4th of July holiday. The
holes matched exactly and the part went in easily. So far my air
conditioner works just fine. Of course, now it has been unusually
cool and I haven't really needed it.
I'm a little late posting this note....and thanking everyone....right
after I fixed the air conditioner I had a computer meltdown and was
off the air for several days. Today everything at my home is working
fine including the computer. I wonder what tomorrow will bring.

Before you spend money. Try spacing the long tube (from the
thermostat) away from the evaporator. About 3/8 to 1/2 inch
or so. If the sensor tube is touching the cold coils, the
sensor may get cold before the air temp indoors is cold.
Please take the cover off the unit. And clean the condensor
(the hot radiator in the back). Inside and out. You may need
somthing like a tooth brush to get the inside surface of the
coil. Use detergent and hot water. Rinse well, with a water
Low charge can cause lower temps. But, the quick cold action
suggests the compressor is doing its job.
My suggestion of the overload was because of the age
of the window unit. If he cleans it and it still does
the same thing, it's probably the overload. A few months
ago, my friend and me cleaned an old unit he had in a
front room of his home. After cleaning, it was behaving
the same way as the OP's AC. It turned out to be the
overload relay under the connection cover of the comp.
I found a link that can explain it better on, of all
places, a coke machine page.
