Mounted on the heat exchanger or blower housing, this snap-disc switch shuts down the burners if the furnace overheats — protecting the heat exchanger and preventing dangerous conditions. A failed limit switch causes short cycling, no-heat lockouts, or a furnace that won't fire at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary high-limit snap-disc switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature:\u003c\/strong\u003e 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat protection \/ burner cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman WFD195090S5DAB and compatible furnace models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Limit switches are life-safety components, and the trip temperature must match the furnace's original design. Genuine OEM 20162903 switches are calibrated to the exact 150°F factory setpoint and mounting footprint. Generic switches with slightly different trip points or bracket geometry can nuisance-trip or fail to protect the heat exchanger.
