This normally-open switch verifies that the inducer draft motor is producing correct venting airflow before the control board allows the burners to ignite. When the switch senses the proper negative pressure of -0.33 inches of water column (WC), it closes and signals the board that it is safe to proceed — a critical safety function that prevents unsafe or incomplete combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 11112501S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Air \/ draft pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Point:\u003c\/strong\u003e -0.33\" WC (water column)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally Open (NO), single stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WGGE4324A070MAB and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e switch, calibrated to the exact -0.33\" WC trip point specified for your furnace. Generic aftermarket switches often carry loose tolerances that can cause nuisance lockouts or fail to protect against a blocked flue. For a combustion-safety component, matching the OEM setpoint is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Replacement typically takes 15–20 minutes: cut power to the furnace, disconnect the two spade terminals and the rubber tubing, unscrew the switch bracket, and reverse the steps with the new unit.
