This switch continuously monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — typically from a dirty filter, blocked ductwork, or a failed blower. A faulty limit switch is a leading cause of short-cycling and no-heat calls, making this an essential safety replacement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary High-Limit Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH950905DXAD (and related furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature burner shutoff safety\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM 20162903\u003c\/strong\u003e is calibrated to the exact 150°F set point and mounting flange this furnace requires. Generic limit switches with even a slightly different trip temperature will nuisance-trip or, worse, fail to protect the heat exchanger. OEM units also match the factory terminal spacing and bracket geometry for a true bolt-in fit, avoiding gaps that let hot air bypass the sensing element.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Disconnect power, unplug the two spade terminals, remove two mounting screws, and reverse the process with the new switch.
