I have a farmhand 5.0 hp 22 gal compressor model vt6334. When i turn it on the motor hums then trips the breaker. Please help. thanks [email protected]

SOURCE: Electric Air compressor just hums then trips breaker.

usally there is a releaf valve that takes the pressure off the compressor while it is resting. If that pressure is not off when the drive piston starts the motor will overload and blow the the breaker or reset. Check for a releaf valve for when the unit has reached full pressure

It could be a couple of things. First and foremost check the plug and make sure the continuity is good for the wires. I have found sometimes that cords get smashed and the wires will be making contact inside the plastic sheathing. Sometimes you cant see where the problem is visually. Remove the cord from the switch and test the continuity with a meter. Check across the poles to see if there is a connection there that shouldn't be. If there is continuity across poles get a new cord.

If your cord is good then it could be your switch. There may have been arching that caused damage to your switch. Check for burnt marks and any wires that are touching that shouldn't be.

Check all wiring to make sure it is correct.

Lastly, your motor may be stuck. Check motor and wiring.

one of a few things possible, first is that the start capacitor is faulty, second could be the start switch inside the motor, and the third that the pump is not unloaded ( if only happens when the tank has air in it) or the pump and or motor is locked up.
