Manufactured by Honeywell to Carrier factory specifications, this pressure switch monitors the negative pressure (vacuum) created by the draft inducer motor before allowing the ignition sequence to proceed. When the switch fails — or senses improper inducer airflow — the control board locks out the ignition sequence, resulting in a furnace that blows only cold air or shuts down immediately after startup. A failed pressure switch is one of the most common causes of a furnace no-heat call in mid-season.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole Single-Throw) configuration | High-fire pressure switch | Factory-authorized Honeywell-manufactured component | Designed for correct W.C.

Generic alternatives can be mis-rated by ±0.10\" WC or more, causing nuisance lockouts in cold weather or — worse — allowing operation with inadequate flue draft, creating a safety hazard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the furnace and confirm zero voltage before beginning. Tools needed: 1\/4\" nut driver, flathead screwdriver, and a manometer (optional, for verification). Photograph all hose and wire connections before disconnecting.
