The pressure switch is a critical safety component that monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot verify safe flue-gas exhaust, triggering a system lockout — the most common symptom is the furnace or packaged unit attempting to start, then shutting down immediately with no heat delivered. A failed inducer, cracked hose, or blocked drain can also mimic a bad switch, so always verify inducer operation and hose integrity before condemning this part.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.

Off-spec generic switches with incorrect W.C. ratings can cause nuisance lockouts or — more dangerously — allow the system to fire without confirmed draft, creating a carbon monoxide risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power and gas before beginning. Tools needed: 1\/4\" nut driver, flathead screwdriver, and a manometer (recommended to verify W.C. setpoint after install). Disconnect the rubber sensing hose and two wire terminals, then swap and reconnect.
