The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMVM971005CNBA modulating variable-speed furnace and other compatible Goodman and Amana models. This normally-closed thermal switch monitors for dangerous overheating or flame rollout and opens the circuit to shut the furnace down when its trip temperature is exceeded. Because it is a manual reset device, it must be physically reset with the button after a fault — a deliberate design that forces a technician to inspect the cause before the furnace can fire again.
The OEM 10123529 is calibrated to the exact factory trip point and mounting footprint, ensuring the safety system behaves as engineered. Generic switches with drifted set points can nuisance-trip or, worse, fail to trip. On a combustion safety control, only genuine OEM is acceptable.
Moderate (2/5). Turn off gas and power, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Verify correct orientation and never bypass a tripped limit.
