Rated to open at approximately \u003cstrong\u003e150°F\u003c\/strong\u003e, this thermal limit switch monitors heat-exchanger and plenum temperatures and shuts off the burners if the furnace overheats — a critical safety function that prevents heat-exchanger damage and unsafe operating conditions. If your furnace short-cycles, trips on limit, or fails to fire, a faulty limit switch is a common cause.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003ePart Type: Primary Limit Switch (auto-reset thermal)\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GKS90703BXAH (gas furnace)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement — factory-calibrated setpoint\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e limit switch is factory-calibrated to the exact 150°F setpoint your furnace's control board expects.
