The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer motor to confirm proper draft before allowing ignition. When it fails or sticks open, the furnace will lock out before the ignition sequence begins — leaving you with no heat and a flashing fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual pressure switch assembly | Two independent switches included | Each switch features 2 wire terminals and 1 hose port | Factory-calibrated W.C.

Aftermarket units often carry wider tolerances, which can cause nuisance lockouts or — more dangerously — allow ignition under marginal draft conditions. For a safety-critical component like this, OEM is strongly recommended.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and lockout the furnace before beginning. Tools needed: 1\/4\" nut driver, flathead screwdriver, needle-nose pliers. Photograph all hose and wire connections before removal. Inspect inducer hoses for cracks while you have the panel open — a leaking hose is a common root cause of pressure switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
