wont shut off

[herb]

My compressor will not shut off at 120 psi but will start when the pressure drops to 90 psi.

Hi Herb,

It sounds like your pressure switch has gone out and will need to be replaced. It is part #5130028-01 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!
