Craftsman compressors don't live very long. Look to make sure the piston bore is OK. I've had 2 that siezed up after prolonged use. I took one in after 6 months of use and they said it would cost $280 to fix it. A new bigger one was on sale at the time for $259. I asked how they could justify the repair. They just shrugged.

Thanks Todd I guess some of the local bunch is related to the ones out your way ,I guess its time to dig deeper into it ,the piston works and every thing seems like it should work but it don't . May be time to get a new one . This one has only about three hours on time . Thanks for your help Ron in Louisville KY

I have checked the manual-auto switch is there a seprate pressure switch? I know where the regulator control is but don't know of the pressure switch . I know it must have one but don't know where, Thanks for your help , Ron in Louisville KY

Pressure switch is the most common thing to go. It should be a 3x3 box with a lever to switch the compressor off and on. A new one will cost about $30 or so. If the compressor shuts off and you don't hear it release air it's ether switch or a bad or clogged check valve in the line coming out of the tank. Thats how an emglo compressor is not sure about sears. Good luck!
