I installed a new pressure switch cw211300av on my compressor and the compressor keeps running. The safety valve opens at 150psi just wondering what i can do to get the compressor to shut off before the safety valve opens?

Is there a adjustment screw on the pressure switch where I can adjust the pressure? Your help on this would be appreciated.. Thank you
Compressor type:
Reciprocating / piston
Compressor model:
Greg McGahey

Sounds like you need to set the pressure switch to the right pressure, like you suspected.

But I don't know this particular type/model, but it looks like a general purpose one.

Please see my pages about pressure switches for more information on how to adjust the pressure, how they work, etc,etc:


Good luck!
