This thermally-activated safety switch opens the control circuit if furnace temperatures exceed the design limit — protecting the heat exchanger and cabinet from overheating due to restricted airflow, a failed blower, or a dirty filter. When this switch trips or fails open, the furnace will not fire or will shut down on a limit fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eCategory: Limit \/ Safety Switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (trip-point identifier)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMS81405DNBC (Goodman\/Amana gas furnace)\u003c\/li\u003e\n\u003cli\u003eType: Auto-reset thermal limit switch\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement — matches factory trip temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e switch is calibrated to the exact trip temperature the furnace was certified with — the light-blue code guarantees you get the right setpoint.
