Every time I start it and its normal its on auto so it stops after it feels up but when it starts up again it blows the breaker I can't figure out what the problem is.

Alen, the breaker is popping either because the compressor is pulling too many amps or there are too many appliances pulling power from the same circuit at the same time, and there isn't enough to go around.

Drain the tank to zero PSI with the compressor off. Start the compressor after closing the tank drain.

Does it start OK? If so, the motor may be pulling too many amps as it is trying to start against pressure on the piston when there is pressure in the tank.

If this is the case, then look to the UNLOADER VALVE. Make sure that the unloader is working properly. Post more details here is you wish.

Cheers,

Bill
