The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to verify proper venting before allowing ignition to proceed. When the switch fails — or when the pressure it monitors falls outside the rated water column (W.C.) threshold — the control board receives no confirmation signal and locks out the heating cycle. Common symptoms include a furnace or system that attempts to start, runs the inducer motor briefly, then shuts down without ever reaching ignition, often triggering a fault code related to pressure switch failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Low pressure switch | OEM Part# 312926-258 | Factory-calibrated W.C.

Generic aftermarket pressure switches frequently carry imprecise W.C. ratings, which can cause nuisance lockouts or — worse — allow ignition under unsafe venting conditions. OEM is the only safe choice for pressure switch replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power before servicing. Tools needed: flathead screwdriver, needle-nose pliers, and a manometer if verifying W.C. rating post-install. Inspect the rubber hose port and tubing for cracks or blockages before installing the new switch, as a clogged port is a frequent root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
