Rated at \u003cstrong\u003e0.18\" W.C. (water column)\u003c\/strong\u003e, this switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition. When it fails or sticks open, the control board cannot verify proper draft, resulting in a no-heat lockout — often with a pressure switch fault code — before the ignition sequence ever begins. Replacing it with the correct OEM-spec switch restores reliable operation and prevents nuisance lockouts caused by tolerance mismatch from off-brand alternatives.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C. set point | Single-port draft proving switch | Normally open | Compatible with 120V\/240V systems via 24V control circuit | Factory-matched trip point tolerance | Also cross-references Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to the exact W.C. rating required by your unit's inducer. Generic switches often carry wider tolerances (±0.05\" W.C. or more), which can cause false lockouts in cold weather or allow unsafe venting conditions to go undetected — putting both equipment and occupants at risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and lock out the unit before beginning.
