This safety control monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats, protecting against restricted airflow, dirty filters, or blower failure. A tripped or failed limit causes no-heat or intermittent shutdown lockouts; replacing it with the correct OEM switch restores safe operation at the proper trip temperature.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit \/ auto-reset safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentifier:\u003c\/strong\u003e Purple cap (model-specific trip temperature)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens gas circuit on plenum over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement for AMH80403AXAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part No.:\u003c\/strong\u003e 0130F00035\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0130F00035\u003c\/strong\u003e is calibrated to Goodman's exact trip temperature for this furnace — the purple color code matters. A generic limit with a different setpoint can nuisance-trip or, worse, fail to protect the heat exchanger.
