Hi

I think the pressure switch is the problem, check the bleeder valve it may not be releasing the head pressure. Bypass the pressure switch and hook directly to the motor. If the problem still persists, then you have a motor problem. It could be many variables, bad capacitors, switch, governor or windings. You need to check this out if you are a repair person or you'll need to visit a service center to get it checked. Repairing and replacing the compressor needs a proffesional license.

If your compressor won’t shut off, you are facing a very dangerous situation. The compressor will keep compressing air into the tank until:
a)it can’t compress any more because there’s more pressure in the tank than the compressor head can overcome.
b)the pressure relief valve opens to safely vent tank overpressure.
c)neither of the two above happen, and your compressor tanks undergoes catastrophic failure, with significant risk to all and sundry around.
I hope that the PRV(pressure release valve) works.
Regardless, if the compressor won’t shut off, you need a new pressure switch RIGHT NOW. Don’t delay. Your compressor is in trouble if you don’t replace the switch. But regardless of where you get one, get your pressure switch replaced.

Please do accept this solution and revert for further assistance.

Thanks
Rylee

1/4 " air pipe to tank fitting keeps blowing out


If there is a nut on the fitting, remove it and check whether the olive has slid off the pipe. Then replace and tighten fully (tighten by hand and then one full turn with a spanner is the rule of thumb for compression fittings) If the pipe is plastic then you may have a quick release air fitting and the air line should be pushed fully into the fitting as far as it will go.

On start up, the motor ran slow then popped the circuit. plugged it into a 20 amp circuit, it ran a little stronger then shut off without popping the circuit. Motor was hot, and after a short period the...


It sounds like the compressor is trying to start under load because there is a tightness in the pump itself or there is high pressure air in the line between the pump and tank There is a small valve that releases the pressure out of the main pipe that runs between the compressor and tank once the tank is full and the motor automatically cuts off. You know this valve is working by the sound of a short spurt if air being released when the motor cuts off. Releasing this pressure means that the motor is able to restart easily because there is no load. If the valve is not releasing this air, the compressor is trying to start under full load which the motor is not capable of doing, hence the slow running, overheating and popping of breakers due to a current overload as the motor tries to run up to normal peed. Motor burnout is possible if it keeps recurring.

This small release valve is attached to the Pressure control switch that switches the motor On & Off and usually has a small pipe going to it or is incorporated inside the Pressure Control Switch. If the valve appears to be working then it means that the Non-return valve on the input to the tank is not sealing properly and letting air back into the main pipe causing the compressor to start under load. Check both valves for correct operation and replace as necessary.

If all the air side checks out OK the check for low oil level and / or binding in the air pump main drive shaft.

When the compressor comes up to pressure and kicks off, you should normally hear a gasp of air escaping. That gasp is the release of pressure from the compressor itself - not the tank, and it is supposed to get released so that the compressor can restart without being preloaded with compressed air. My guess is that the gasp is not happening. It is probably some debris or a gummy mechanism. The mechanism is supposed to be triggered by the same mechanism that shuts off the motor.
