Your compressor is locked up. i would try replacing the round start capacitor. you need to check what the exact rating for yours is but I believe one of these two will work for ya. In the meantime do not continue to try to run it, it will kill the compressor.

AC Kicking OFF Breaker


Sounds like you have a problem with your compressor. If the beaker trips the second the compressor tries to come on hen it is shorted. If it takes a couple of seconds, then your compressor is locked up.

Duo Therm compressor tries to start and kicks out


I don't think these little units have a start capacitor but what I would do is check that the on/off switch wires to make sure they aren't loose. Also check the wires to the compressor for loose wires as well. It is possible that these are the first signs that the compressor is about to fail. They also can act up some when they haven't been used for awhile and then you try and start them up. Try running the unit for a few hours without asking it to cycle. It might just be a sticky valve.

I suspect that you have a bad selector switch for the on, off, low fan, high fan operation. If the selector switch is put into the off position everything should stop completely.
