The pressure switch monitors negative pressure created by the inducer blower motor to verify proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot confirm safe draft conditions — resulting in a hard lockout, a no-heat call, or a furnace that flashes a pressure switch fault code without ever attempting ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.

Tools needed: 1\/4\" nut driver, needle-nose pliers, and a manometer (recommended to verify draft pressure post-install). Before replacing the switch, inspect the rubber hose fitting for cracks or blockages, as a split hose is a common root cause of pressure switch faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
