Mounted on the burner or blower assembly, this auxiliary limit provides a backup over-temperature cutout in addition to the primary limit — opening the control circuit if a localized hot spot develops from blocked airflow or a venting fault. The light-blue color code identifies its specific trip temperature rating, so matching the exact part matters.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor code:\u003c\/strong\u003e Light blue (denotes trip-temperature rating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ secondary limit switch, safety cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Backup over-temperature protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH81005CNBA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The color-coded 0130F00038 is factory-set to the precise setpoint this furnace requires.
