Mounted on the heat exchanger or blower deck, it constantly monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger and preventing a fire hazard when airflow is restricted by a dirty filter, blocked ductwork, or a failed blower. A furnace that fires briefly then shuts down, or that short-cycles on heat, is often signaling a faulty primary limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas valve circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMEC800803BXAB and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eCategory: Limit switch \/ Safety control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM control\u003c\/strong\u003e is factory-calibrated to the trip and reset temperatures specified for this furnace. Generic limit switches may carry a different temperature rating or mounting footprint, which can lead to nuisance trips or, worse, a switch that opens too late.
