Craftsman 921.164710 air compressor
I have the 921.164710 and it was shutting off at 50psi.
I adjusted the cutout and it didn't change anything.
I replaced the switch for $75 and its still cutting off at 50psi, even after adjusting the cut out again.
Please someone have some insight on this.
6.5 hp craftsman oil less compressor shuts down after 10 min
My compressor shuts down after 10 min or so of use.
It pump up to 140 psi an shuts off but motor will shut down and will not come back on after it warms up after use.
Is there a cut off switch on motor that has gone bad.

Compressor runs great when not connected to the tank.
When's it's connected to the tank and starts building air it starts cutting on and off and trips breaker.
Installed new pressure switch.
When you unhook the line going into the tank it runs fine and theirs lots of sir comeing out of the line.
As soon as you hook it back up and it starts building air in the tank it cuts on and off.
I looked inside the pressure switch and I can't tell where the switch might be kicking it on and off that part looks good.

it was working fine for 3hrs but then it just turn off and i just drained it because i was hoping it was going to start with the low pressure but no. i already check the circuit breakers at the house the socket on the garage the electric core on the compressor but its the same no start any ideas or suggestions
Good that you checked power at the socket, Mike. Now, with the tank empty, your pressure switch should have tripped to passing, meaning that the power should be flowing across the switch to the motor circuit.
Your next check is to use a multi-meter to do that, from inside the pressure switch housing. Be careful, live wires.
