Mounted on the heat-exchanger or blower deck, this primary high-limit switch continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, it opens the circuit to shut down the gas valve, protecting the heat exchanger from thermal damage — then automatically resets once temperatures return to a safe range.\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\u003c\/li\u003e\n\u003cli\u003eFunction: Normally-closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting on cooldown)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMVM97 series furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM limit control\u003c\/strong\u003e is factory-calibrated to the precise trip and reset temperatures your furnace requires and matches the original mounting bracket and terminal layout.
