    I think is a single ph unit cause the external overload, chattering could be due to the locked compressor drawing high amps trying to star and voltage taking a dive. with the limited info provided everything is a guess.

    Rocket, try reversing star and run, turn it on and hit it hard with a 2X4

    If it isn't an electrical problem, I would agree with valdelocc. Check your refrigerant charge. Also the problem could be contamination in your refrigerant line. Check your filter/dryer, if your refrigerant is entering the compressor with contaminates or still in liquid form then that is bad for your compressor. Not enough refrigerant in your compressor could be causing the overheating.

    Write this down-ALWAYS check your power coming in. Then check the contacts on the contactor and power at the motor (compressor). Also never run anything that is over RLA. Also when it stopped what did it stop on? Thermal overload or phase monitor? A safety or did a winding burn apart? What kind of compressor? Ohm out windings. Lost a leg on the 3 phase? Is it 3 phase? More info=better answers.

    Yes it is 3 phase, What i think happen is that flooded the compressor on start up and cooked the compressor bearings, i am going to pump it down. realse the pressure and open the head. I wish it was an electrical problem but seems like i am going to have to replace the compressors maybe??? , compressor tries to start but doesnt crank over.

    have you try reversing the rotation?

    No oil pressure switch? Takes a while to seize em up on washed oil.
