This thermally activated switch provides supplemental overheat protection — commonly guarding the blower compartment or a secondary heat-exchanger location — and opens the control circuit to shut down the burners if temperatures exceed a safe threshold. The light-blue color code identifies its specific trip rating, so matching the exact part is essential. A tripped or failed auxiliary limit is a frequent cause of no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auxiliary \/ secondary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor code:\u003c\/strong\u003e Light blue (trip-rating specific)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Thermal limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Supplemental overheat \/ rollout protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e AMS80603AXAA (and compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM auxiliary limit\u003c\/strong\u003e is factory-calibrated to the trip temperature indicated by its light-blue coding.
