The pressure switch monitors negative pressure created by the draft inducer motor to verify safe venting conditions before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot confirm proper inducer operation and the furnace will lock out — typically displaying a fault code — before the burners ever fire, leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Rated at \u003cstrong\u003e-.33 inches W.C.

Aftermarket pressure switches often deviate in trip point accuracy, risking nuisance lockouts or — more dangerously — failing to detect a blocked flue. OEM is always the correct choice for a safety-critical component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off power and gas before beginning. Disconnect the rubber hose from the inducer port and unplug the two wiring harness terminals. Remove the old bracket screws, mount the new switch with the included bracket, and reconnect hose and wiring. Tools needed: flathead and Phillips screwdrivers, 1\/4\" nut driver. Verify hose integrity before reassembly — a cracked hose is a common cause of pressure switch faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
