This single-pole switch is calibrated to a \u003cstrong\u003e-.10 inch water column (WC), normally open\u003c\/strong\u003e set point, monitoring inducer draft to verify proper venting before the ignition sequence begins. A failing pressure switch is a common cause of furnaces that lock out, short-cycle, or throw draft\/flame-proving fault codes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20197308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Point:\u003c\/strong\u003e -.10\" WC (negative pressure)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Action:\u003c\/strong\u003e Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Condensing\/gas furnace draft proving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH950453BXAF and compatible Goodman\/Amana units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine OEM Goodman component\u003c\/strong\u003e, factory-calibrated to the exact trip point your furnace's control board expects. Generic universal switches can be sourced cheaper but often carry a different actuation pressure or hose barb orientation, leading to nuisance lockouts. For a safety-critical control, we recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate\u003c\/strong\u003e — Typically a 15–20 minute repair: disconnect power, transfer the sensing hose(s), swap the two spade terminals, and reinstall. No special tools required. A manometer is recommended to confirm actual draft pressure against the switch rating.
