Positioned over the heat exchanger, this high-limit switch continuously monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically due to restricted airflow from a dirty filter, blocked ducting, or a failing blower. Unlike the manual reset rollout switches, the primary limit is an automatically resetting control that closes again once temperatures return to a safe range, allowing normal operation to resume.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner circuit on over-temperature, auto-resets on cooldown\u003c\/li\u003e\n\u003cli\u003eLocation: Heat-exchanger \/ supply-air limit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana furnaces including AMH950904CXAE\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM 20162904 is calibrated to the precise trip and reset temperatures Goodman engineered for this furnace, with the correct mounting bracket and insertion depth.
