Cut off pressure is low

by Adam
(Fullerton, CA)

my CH compressor should cut off the motor at 135psi, but has recently started to cut off at 75psi. Intermittently it will still compress all the way to 135, but not consistently. This is making it really hard to run the spray gun.

Cut off pressure
by: Bill

The absence of your Campbell Hausfeld compressor model number makes it a bit difficult to be specific, Adam.

Typically, if the cut in or cut out pressure of an air compressor becomes erratic, it suggests that the internal pressure switch diaphragm is failing, and that indicates that it's time to replace the pressure switch.

Cheers,

Bill
