The pressure switch monitors negative pressure created by the draft inducer motor to confirm safe venting conditions before the ignition sequence is allowed to proceed. When it fails or sticks open, the furnace control board never receives proof of inducer operation — resulting in a hard lockout before ignition, a blinking fault code, or a furnace that attempts to start and immediately shuts down. This is one of the most common causes of a furnace that \"clicks but won't light.\"\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.

Generic aftermarket switches often carry wider W.C. tolerances that can cause nuisance lockouts or, worse, allow ignition under unsafe venting conditions — a critical safety risk. Always use OEM on pressure switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and tag out the unit before starting. Tools needed: 1\/4\" nut driver, needle-nose pliers, and a short length of replacement silicone tubing (recommended). Photograph the hose and wiring connections before disconnecting. Inspect inducer hose for cracks or blockages while the switch is out — a clogged hose is often the root cause of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
