The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM flame-rollout safety control for the AMS80403AXAA gas furnace and related Goodman/Amana models. It permanently opens the ignition circuit if flames roll out of the burner box — a critical indicator of a cracked heat exchanger or blocked flue — and requires a deliberate manual reset to restore operation.
The OEM 10123529 carries Goodman's factory-set trip temperature for guaranteed rollout protection and warranty compliance. Our Generic equivalent replicates the trip rating and mounting pattern at a lower cost for out-of-warranty service.
Easy (1/5). A 5–10 minute repair. Shut off gas and power, remove the two mounting screws, swap the spade connectors, and remount. Important: if this switch tripped, diagnose the root cause (blocked vent or cracked heat exchanger) before returning the furnace to service.
