This normally-closed thermal switch opens the ignition circuit if it senses an over-temperature or flame-rollout condition, shutting down the burners to protect the heat exchanger and cabinet. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it requires a technician to press the reset button after clearing the underlying fault — a deliberate safeguard that flags a real problem rather than silently cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual Reset High-Limit \/ Rollout Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration:\u003c\/strong\u003e Normally closed, opens on temperature rise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMS80403AXAC (80% AFUE gas furnace)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman limit switches are calibrated to the exact trip temperature the AMS80403AXAC was engineered around. A generic switch with the wrong set point can trip prematurely (nuisance lockouts) or — far worse — fail to trip during a real overheat. On a life-safety component, OEM calibration is not optional.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5)\u003c\/strong\u003e — Two spade terminals and typically two mounting screws. Cut power and gas first, note wire positions, and never bypass a limit switch.
