It sounds to me as though the pressure switch is shorting out when it trips to OFF at cut out.

If this were my compressor, I would be replacing the pressure switch.

Brute air compressor won't build up pressure due to tear in gasket

by Kasi

I have a brute air compressor and under the pressure switch, there is a gasket or seal (black) of some sort that has a tear. Where can I find a new one? I don't know the part number either.

When you say under the pressure switch, do you mean under the pressure switch cover? Usually pressure switches are hard-piped into the air circuit, and I don't know what the "gasket or seal" under the switch might be.

If it's the diaphragm inside the pressure switch that has the tear, I suspect parts will cost you as much as a new switch.

Cheers,

Bill

Pressure switch on 6 gal. pancake air compressor

by Bobby Price

Just recently my compressor started excedding the 150 PSI point. It will run to 160 or more, til the safety relief value kicks out. Is there any way to get it back to the factory setting?

I don't know the model of compressor you have, nor the make, so I don't know what pressure switch you currently have.

In my opinion trying to repair a pressure switch is a waste of time in trying to find parts, learning how to disassemble and reassemble a compressor pressure switch, versus spending the $20 - $40 for a new one.

I suspect your compressor switch has failed, and it's time for a new one. If this were my air compressor, I would not use it again until I got the switch replaced.
