This safety control monitors the inducer draft and proves proper venting airflow before the ignition sequence is allowed to continue.

If your furnace ignites briefly and then shuts down, or fails to start with a pressure-switch fault code, this is a common culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eActuation setpoint: -0.10\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eContact configuration: Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eApplication: Inducer \/ vent draft proving\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20197308\u003c\/li\u003e\n\u003cli\u003eFits: AMH950905CXAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (Daikin)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eGenuine OEM 20197308\u003c\/strong\u003e matches the factory pressure setpoint, hose-port size, and mounting pattern exactly — critical because an out-of-spec switch will nuisance-trip or fail to prove airflow, causing lockouts.
