The pressure switch is a critical safety component that monitors the negative pressure (inches of water column) created by the inducer motor to confirm proper venting and airflow before allowing the ignition sequence to proceed. When this switch fails — or if the diaphragm cracks or the hose collapses — the control board never receives the \"inducer proven\" signal, resulting in a hard lockout before any ignition attempt. Common symptoms include a running inducer fan with no subsequent ignition, a flashing fault code indicating a pressure switch error, or a system that immediately locks out on a call for heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched W.C.

Aftermarket pressure switches often carry wider trip-point tolerances, which can cause nuisance lockouts or — more dangerously — allow operation under marginal venting conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Straightforward swap once the unit is de-energized. Tools needed: 1\/4\" and 5\/16\" nut drivers, needle-nose pliers to remove rubber hose, and a multimeter to confirm open\/close operation before reinstallation. Always inspect the rubber inducer hose for cracks or blockages — a failed hose is frequently misdiagnosed as a failed switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
