Product Overview

If the compressor will not start at low tank pressure, will not shut off near full pressure, or hisses continuously at the unloader, the pressure switch deserves a close test.

For the repair to hold up, the part still has to match the original application. This assembly controls motor cycling between approximately 135 PSI cut-in and 175 PSI cut-out and includes the manual lever and unloader function used on compatible systems. Verify motor phase, wiring, manifold, and pressure ratings first.
