When a Coleman-Mach rooftop AC starts acting up electrically, the pressure switch relay is one of the components technicians check as part of diagnosing the system. This is the genuine Coleman-Mach replacement part, packaged for a direct swap in compatible units.
It ships as a small, compact part rather than a full assembly, so it's intended for a targeted replacement once you've confirmed the relay itself is the failure point on your specific AC model.
Match this against your AC unit's model number and service documentation before ordering to confirm compatibility.
