33 Gallon, 6HP Craftsman Air Compressor

For a long time it cuts on and off at times. Lately, it will not cut off and the PVR valve pops. I was wondering if it might be the check valve causing the problem and if so, how do I fix or check that?

Hi Mona. From the information provided, I don't believe it is your check valve. I think your problem is the pressure switch.

Here is more info on pressure switches, to give you more understanding.

Cheers,
