The pressure switch is a critical safety component that proves the inducer motor is producing adequate negative pressure before allowing the control board to proceed with ignition. When it fails or sticks open, the furnace will typically lock out before the ignition sequence begins — leaving you with no heat and a flashing fault code indicating a pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.

Generic alternatives often carry wider tolerances, which can cause nuisance trips or — worse — fail to detect a true blocked flue condition, creating a safety hazard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and lock out the furnace before beginning. Tools needed: 1\/4\" nut driver, flat-head screwdriver, needle-nose pliers.
