Mounted near the blower deck or heat exchanger, it provides a backup overheat cutoff that de-energizes the furnace if temperatures rise beyond safe limits — for example during a blower failure or severely restricted airflow. It works alongside the primary limit switch to keep the heating cycle within a safe operating window.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary \/ secondary high-limit switch\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eFunction: Backup overheat safety cutoff\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \/ Amana furnaces including AMSS921005CNAA\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe color-coded housing corresponds to a specific trip temperature, so matching the \u003cstrong\u003egenuine OEM\u003c\/strong\u003e part guarantees the correct calibration.
