This auxiliary limit backs up the primary high-limit, opening the gas valve circuit if it detects abnormal heat near the blower compartment or burner area — a common cause of intermittent no-heat lockouts on furnaces with restricted airflow. The color-coded light-blue housing identifies its specific temperature rating, so matching the OEM part number is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Normally closed, opens on overheat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Secondary overheat safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana OEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e ACES960403BNAA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM auxiliary limit\u003c\/strong\u003e is calibrated to the exact trip temperature indicated by its light-blue color code.
