The pressure switch is a safety device that monitors the negative pressure (draft) created by the inducer motor to confirm proper venting before allowing ignition to proceed. When it fails or sticks open, the furnace will lockout before ever reaching the ignition stage — leaving you with no heat and typically a blinking fault code indicating a pressure switch failure. A faulty or clogged switch is one of the most common causes of furnace no-heat calls in the field.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Rated W.C.

Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, and a digital manometer (recommended to verify inducer pressure post-install). Inspect the rubber pressure hose for cracks or blockages while the switch is out — a clogged hose 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.
