The pressure switch is a critical safety device that monitors negative pressure created by the inducer draft motor to confirm adequate airflow before allowing the ignition sequence to proceed. When this switch fails, the control board cannot verify safe venting conditions and the system will lock out — resulting in no heat and a fault code indicating a pressure switch error.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched W.C.

Aftermarket pressure switches with incorrect trip points can cause nuisance lockouts or — more dangerously — allow the unit to fire under unsafe draft conditions. OEM is strongly recommended for this safety-critical component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Disconnect power before servicing. Tools needed: 1\/4\" nut driver, flathead screwdriver, manometer (recommended to verify switch operation post-install). Inspect inducer hose and port for blockage or cracks before replacing the switch, as blocked ports are a common root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
