This switch monitors furnace temperature and opens the burner circuit if a high-temperature or flame-rollout condition is detected, protecting the heat exchanger and surrounding cabinet from overheating. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it stays open after tripping until an operator physically presses the reset button — a deliberate design that forces a service inspection before the furnace is allowed to fire again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner circuit on overheat, requires manual reset\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana GMPE100-4A and compatible furnace platforms\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003efactory OEM component\u003c\/strong\u003e — calibrated to the exact trip temperature specified for the GMPE100-4A. Generic replacements often use approximate trip points and looser tolerances, which can cause nuisance lockouts or, worse, fail to trip at the correct temperature.
