The Goodman 10123539 Manual Reset Limit Switch is a genuine OEM safety control for the Goodman/Amana AMVC960603BNAA gas furnace. This normally-closed thermal switch acts as a flame-rollout or high-limit safety cutout: if temperature at its mounting point exceeds the trip threshold, it opens the circuit and shuts down the burner to prevent unsafe operation.
Because it is a manual reset device, it will not automatically re-close after tripping — it must be reset by hand once the fault (blocked flue, failed inducer, dirty burners) is corrected. A switch that repeatedly trips or fails to reset should be replaced with this exact OEM part.
OEM vs. Generic: Because this is a life-safety component, the OEM 10123539 is strongly recommended — it is calibrated to the furnace's exact trip temperature. Generic switches with a different set point can nuisance-trip or, worse, fail to trip when needed.
Install difficulty: Easy (2/5). Disconnect power and gas, unplug the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. Verify furnace cycles normally afterward.
