The pressure switch is a safety device that monitors negative pressure created by the inducer draft motor. Before allowing ignition to proceed, it confirms the inducer is operating correctly and that the flue path is clear. When this switch fails — or becomes stuck open — the control board cannot verify proper draft, and the furnace will lock out before ever reaching the ignition stage. Common symptoms include a furnace that runs the inducer but never advances to heating, repeated error codes for pressure switch faults, or a furnace that attempts ignition briefly before shutting down entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Factory-calibrated W.C.

Aftermarket pressure switches frequently carry wider tolerances that can cause nuisance lockouts in cold weather or — more dangerously — fail to trip when a real venting problem exists.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power and gas before servicing. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to confirm open\/closed continuity). Inspect the rubber hose connecting the switch to the inducer for cracks or moisture before reinstalling — a bad hose causes the same symptom as a bad switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
