The pressure switch is a critical safety device that monitors negative pressure produced by the inducer (draft) motor before allowing ignition to proceed. When the inducer creates the correct draft, the diaphragm inside the switch closes the circuit and signals the control board to advance to the ignition sequence. If the switch fails — or if it senses insufficient draft — the furnace will lock out on a pressure switch fault, typically displaying a fault code and delivering no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e -0.33\" W.C.

Off-brand switches with loose tolerances can cause nuisance lockouts or — worse — fail to detect a true venting fault, creating a safety risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power off the furnace at the disconnect before starting. Tools needed: 1\/4\" nut driver, needle-nose pliers, and a short length of replacement tubing (if hose shows cracking). Always inspect the rubber hose port and hose itself for blockage, cracks, or moisture before condemning the switch — these are the most common root causes of switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Backed by a 1-year OEM manufacturer warranty.
