Mounted on the burner assembly, it senses abnormal heat from flame rollout and immediately opens the gas-valve circuit to shut the furnace down. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it stays tripped until an operator presses the reset button — a deliberate design that flags a real combustion problem rather than silently cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual reset rollout \/ flame limit switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eCircuit: Interrupts gas valve \/ control circuit on trip\u003c\/li\u003e\n\u003cli\u003eFitment: Amana \u0026amp; Goodman furnaces (AMSS920803BNAA and related)\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123539\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10123539 is calibrated to the exact trip temperature specified for this burner box and uses factory terminal spacing and bracket geometry for a bolt-in fit.
