This normally-closed thermal switch opens the burner circuit if the heat-exchanger plenum temperature exceeds its \u003cstrong\u003e150°F\u003c\/strong\u003e cutout point, shutting down the furnace to prevent overheating and protect the heat exchanger. A failed or drifting limit switch is a common cause of short-cycling, no-heat, and repeated soft lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1370198\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutout temperature:\u003c\/strong\u003e 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMT070-4B and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Genuine OEM Goodman replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is the factory-specified OEM part, calibrated to the exact trip point your furnace's control logic expects.
