The pressure switch is a normally-open safety device that monitors negative pressure generated by the inducer motor during the pre-purge cycle. Once the inducer establishes sufficient draft, the switch closes and signals the integrated furnace control board to proceed with ignition. When this switch fails — or the hose, port, or inducer motor connected to it degrades — the furnace will lock out before ignition, display a pressure switch fault code, and deliver no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM pressure switch assembly | Includes factory mounting bracket | Single-stage operation | Set point rated at -0.27\" W.C. break \/ -0.42\" W.C. max make | Spade terminal connections | Compatible with induced-draft gas furnace design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM part, manufactured to exact factory tolerances. Generic aftermarket switches (available separately at lower cost) often carry ±10–15% W.C. set point variance, which can cause nuisance lockouts or — more dangerously — fail to trip under true fault conditions. For a safety-critical device like a pressure switch, OEM is strongly recommended.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Straightforward swap on most technicians' scales. Turn off power and gas before servicing. Tools needed: 1\/4\" nut driver, flathead screwdriver, needle-nose pliers. Inspect and blow out the rubber hose port before installing the new switch — a clogged hose is a leading cause of false pressure switch failures. Always verify proper inducer operation after replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e Backed by Carrier's 1-year OEM parts warranty.
