This high-limit switch continuously monitors heat-exchanger and plenum temperatures, shutting down the burners if the furnace overheats to protect your equipment and home. A failed primary limit is a common cause of short-cycling, no-heat calls, and lockout faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 0130F00035\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch (manual\/auto reset per spec)\u003c\/li\u003e\n\u003cli\u003eColor Code: Purple\u003c\/li\u003e\n\u003cli\u003eFits Model: GDH80403AXAA\u003c\/li\u003e\n\u003cli\u003eApplication: 80% gas furnace, primary overheat protection\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is factory-calibrated to the exact trip and reset temperatures your furnace's control board expects — critical for a safety component.

Always shut off gas and power at the disconnect before servicing. A basic multimeter (continuity check) confirms diagnosis.
