AIR ESCAPING FROM PRESSURE SWITCH
(CONTOOCOOK NH )
INGERSOL RAND COMPRESSOR WITH PRESSURE SWITCH 1R 56288772-02
IS THEIR A NEEDLE VALVE INSIDE THE PRESSURE SWITCH?
WHEN I SHUT OFF THE BREAKER I CAN MANUALLY TRIP WHICH I BELIEVE THE UNLOADER VALVE AND THE AIR STOPS EXCAPING WHEN THE BREAKER IS ON
THIS SWITCH CALLS FOR AIR AND TURNS ON THE AIR COMPRESSOR CAN YOU DIRECT ME
Steve, you cover a bunch of stuff in your post, and I'm not sure what model of IR you have.
The first thing I would do is dump the tank air with the compressor off, pull, disassemble, clean and reinstall the tank check valve. Does that make any change?
