Hmmm. Compressor running, and - we assume - compressing refrigerant, which will heat it up.
Can there be a blockage in the system somewhere, frozen place or?? Is there supposed to be a fail-safe kick-out that has failed?
The symptoms of cold at first, then not, sound like a freeze-up somewhere. A real solid freeze-up. The time from hot air blowing to cold the next morning is likely a largee number of hours. How about a test to see if that number is smaller, just enough time for the freeze-up to thaw out. Maybe four hours, Two? Six?
Good Luck,
Bob
