Compressor is likely shorted to ground. Turn breaker off, take the fan off and unplug the compressor. Put the fan back on and turn power back on with a call for cool. If fan runs and breaker holds the compressor is bad.

Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

First off, be sure the pigtail is wired correctly to the back of the unit. Black and red to the outside terminals, white to the middle, green to the frame or cabinet (should be a green screw close-by). If that is ok, you probably have an issue with possibly a bad pigtail, bad outlet, wiring issue, or possibly a bad circuit breaker or breaker box. Probably going to be more of a electrical problem than a appliance problem. Good Luck!!!!

If your outside condenser has a locked rotor or short circuit, than the unit WILL trip the breaker - as it should. On the other hand if a breaker is tripped a few times it will have less of a capacity that the rating, (this is designed in it). You will need to determine if the unit is locked (and broken) or the breaker has become too sensitive.

a full size refrige has to be on a 20 amp circuit, a 15 amp is just not big enough.. you should also know that this circuit has to be on a 12-2 gauge wire.. I also highly recommend installing a 20 amp HD receptacle
SOURCE: Pond pump trips circuit breaker
The circuit breaker trips because there is an electrical short in the pump itself or in the wire feeding the pump. A cause of this could be a bare wire, or a crack in a wire. Remove the pump and put it in a five gallon pail of water and test it. If it still trips the breaker you will know the problem is in the pump or the cord to the pump.
