Mounted on the heat exchanger or blower deck, this normally-closed thermal switch monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — the primary protection against heat-exchanger damage and fire. A furnace that short-cycles on high heat, will not fire, or trips repeatedly often has a failed primary limit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens on over-temperature to shut off the gas valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMEC960803BNAA and related 96% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Factory-calibrated trip point matched to the furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM 20162904 ships with Goodman's exact trip and reset temperatures, mounting bracket, and terminal orientation. Generic limits with a different set point can nuisance-trip or, worse, fail to trip at the correct temperature — a genuine safety concern.
