This normally-closed thermal switch opens the control circuit if it senses excessive temperature — typically from a dirty filter, blocked return, or blower fault — shutting the burners down before the furnace overheats. A tripped or failed limit is a common cause of no-heat and short-cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Auxiliary (rollout\/overheat) limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Limit Switch \/ Safety Control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light Blue (temperature-rating specific)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e AMS81205DXAB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are color-coded to a specific trip temperature — the \u003cstrong\u003elight-blue OEM Goodman\u003c\/strong\u003e switch is calibrated for the AMS81205DXAB.
