Mounted on the heat exchanger or blower deck, this normally-closed safety control monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger, ductwork, and your home from unsafe temperatures.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (auto-reset high limit)\u003c\/li\u003e\n\u003cli\u003eFunction: Primary limit \/ over-temperature safety\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eFits Model: AMH81405DXCA (and compatible units)\u003c\/li\u003e\n\u003cli\u003eCategory: Safety Controls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM switch is calibrated to the exact trip point specified for this furnace's airflow and heat-exchanger design. A generic limit switch with a different set point can trip too early (short cycling, no heat) or too late (a real safety risk). Because this is a life-safety control, the genuine 150°F OEM part is the correct choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — Turn off power, remove two mounting screws and the spade wire connectors, and swap in the new switch.
