The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the Goodman/Amana AMH80603AXBA gas furnace. This normally-closed switch monitors for excessive heat or flame rollout at the burner box and opens the circuit to shut off the gas valve when a dangerous over-temperature condition occurs. Because it is a manual reset device, it will not automatically re-close — it must be pressed to reset, which alerts you that a fault occurred and needs attention.
Limit switches are calibrated to a specific trip temperature. The OEM 10123529 is set to the exact factory spec for this furnace, ensuring it trips at the correct threshold — not too early (nuisance shutdowns) or too late (safety risk). Generic switches with different trip points are not recommended for safety-critical rollout protection.
Difficulty: Easy (1/5). A 10–15 minute job: cut power, disconnect the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. If the switch has tripped, always diagnose the root cause (blocked flue, cracked heat exchanger, or overheating) before returning the furnace to service.
