The little compressors were not built for continuous duty. The pump probably seized, or the motor burned up, or both.

SOURCE: Extra fitting on my Porter Cable?

The porter cable compressor is equipped with a pressure relief valve. Mine has a ring attached to it. When you pull out on the valve, it releases all the pressure stored in the tank. Try pushing that valve back in, or if faulty replace it.

SOURCE: Porter cable pancake unit blows air after shut off.

tap on the check valve with a metal object. Its sticking open. The check valve is the brass fitting on top of the tank. When the valve sticks open it emits air from the area of the engine. If that doesn't work (which I would be surprised it doesn't), you'll need to purchase a new check valve. Good Luck!

SOURCE: Have a Porter Cable 175 PSI, 25 gallon upright

On these larger compressors, the motor that turns the compressor,

will have one or two capacitors, the capacitor in conjunction with the

motor gives the compressor that extra push or torque that is required

to get it going. if the capacitor goes out, the compressor will not work,

the motor may work but will not have the strength to turn over the compressor..

depending on the size motor, it may be mounted on top, on the side or

even in a juntion box attached to the compressor, if you have to replace one

i recommend powering down or unplugging compressor and handle the

capacitor carefully, use insulated tools or gloves, a capacitor is like a battery

it will hold a charge, but like a battery it can be discharged, the only difference

with a battery and a capacitor, on a capacitor you can have thousands of volts.

it can be replaced just handle it safely, good luck!

Trips breaker after a few seconds of run time.

Start capacitors are disconnected when it is reach a full RPM.
Use a AVR tester - measure AC voltage across capacitors. It shall be off in a few seconds after is running.
If not - centrifugal switch or its components are problem.

Try to use a higher amperage extension cord.
This unit is rated for 15 amps. It should be able to run on a 20 amp circuit unless there is voltage drop due to small wiring. Try an air conditioner extension and let us know the result.

I have a porter cale C5101 compressor. It hesitate to auto start when the pressure is low, always trip my circuit breaker.

What amp breaker do you have this hooked to. I would use no less than 15 amp ,preferrably a 20 amp. Next do you drain tank after use on a regular basis. If you don't moisture can build up inside tank and cause hard starting on automatic. If you need to drain tank there should be a drain valve on bottom of tank. try turning it counterclocwise with compressor off. If it dosen't turn that way try clockwise,air and moisture should drain. If you have alot of water in tank then shut valve and turn compressor on and bring to full pressure,then repeat draining procedure until no more water comes out. Hope this helps. Thank you

My c3151, loads to tank fine then the unit will cut in and out. The unit will trip a breaker. Is this an easy fix?

the line from the compressor to the tank should have a check valve .so that the compressor head does not have pressure for easy start up... check and replace if needed. when compressor attempts to start its to dificult with the pressure, causing circuit overload.
