My Craftsman air compressor will not turn on or power up?
(Mt. Vernon, OH USA)
My Craftsman air compressor was working perfectly fine Friday and Saturday while in use.
I plugged it in Sunday to finish up a break job I was doing and moved the lever to power it up and nothing happened.
Checked the plug, breaker all were unfazed. Don’t know if it’s the power switch or something in the motor. Need help and suggestions. Found out from Sears that the power switch is no longer available and there were no suggestions on replacement power switch.
Scott, assuming there is actually power flowing to the compressor pressure switch, the question is, is the power flowing through the switch to the motor?
Turn off the compressor. Drain the tank pressure to zero. Turn the compressor back on. If it doesn’t start, put a meter on the line from the pressure switch to the motor and make sure power is flowing.
If not, change the pressure switch.
Take that one with you to the compressor store when you go to buy a new compressor pressure switch. I expect you’ll find it’s a pretty standard switch and finding another that suits will be possible.
How do you change the Craftsman pressure switch cut in level?

how do you change the cut in level on a craftsman 60 gallon upright oil less compresses? it just seams to take so long before it cuts in when i’m sand blasting.
I’m a bit confused by your statement, Gary. Sandblasting is usually a very high air demand application. This means that usually the air tank is depleted quickly, and the compressor motor cuts back in often to try and keep up with the demand.
That it takes a long time before your compressor cuts in is a good thing, in that, it suggests that your compressor can keep up with the demand.
So, my question is, what is the pressure setting on your regulator?
If the issue isn’t air flow, but air pressure, turn up the pressure on the regulator to get higher pressure and flow to the sandblaster.
If you must tinker with the pressure switch, read the page on Pressure Switches on this site for details. I advise against adjusting the switch, however.
