Mounted on the heat-exchanger bulkhead, this automatic-reset switch monitors supply-air temperature and interrupts the gas valve if the plenum overheats — typically from a dirty filter, blocked ductwork, or failed blower. It restores automatically once temperatures return to a safe range.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH951155DXAG and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The 20162903 is calibrated to the precise 150°F trip point and disc diameter the furnace control sequence relies on.
