Mounted on the heat exchanger bulkhead, this high-limit switch continuously senses supply-air temperature. If airflow is lost — from a dirty filter, failed blower, or blocked ductwork — and the plenum overheats, the limit opens the gas valve circuit to shut down the burners, protecting the heat exchanger from thermal damage and preventing an unsafe condition.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Automatic-reset supply-air overheat cutoff\u003c\/li\u003e\n\u003cli\u003eMounting: Heat exchanger \/ blower bulkhead bracket\u003c\/li\u003e\n\u003cli\u003eFits: Goodman AMS81005CXAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: Quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\n\u003cp\u003eThe primary limit's trip temperature and bracket length are matched to this furnace's cabinet. An OEM 20162904 restores the exact factory set point; a generic universal limit may trip early (nuisance shutdowns) or too late (inadequate protection). For heat exchanger safety and warranty integrity, use the OEM control.\u003c\/p\u003e\n\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEasy to Moderate (2\/5).\u003c\/strong\u003e Held by two screws with two spade connectors; typically a 20-minute repair.
