Mounted on the heat exchanger or blower deck, this auto-reset control monitors supply-air temperature and shuts off the burners if the furnace overheats — typically due to restricted airflow, a dirty filter, or blower failure. It is a critical safety component that protects the heat exchanger from cracking and prevents overheating conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting once temperature normalizes)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman \u0026amp; Amana AMS950703BXA and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162903\u003c\/strong\u003e guarantees the correct 150°F calibration, bracket span, and terminal layout for this furnace.
