The Goodman 10123534 is a genuine OEM manual reset limit switch for the AMES920804CNAA gas furnace. This thermally activated safety control monitors furnace temperature and opens the circuit to shut down the burner if an overheat or flame-rollout condition is detected, protecting the heat exchanger and the home.

Because it is a manual reset device, the switch stays tripped until it is physically reset — a deliberate design that forces a technician to inspect for the underlying cause (blocked airflow, failed blower, or cracked heat exchanger) before the furnace can restart. Replace it only with the correct trip-temperature part.

OEM vs. Generic

Safety switches must match the factory trip temperature and mounting exactly. The OEM 10123534 is calibrated to your furnace's specification; a generic switch with the wrong set point can nuisance-trip or, worse, fail to protect the unit. For a life-safety component, always use the genuine OEM part.

Install Difficulty

Moderate (3/5). Two-wire swap with a mounting screw, but correct placement is critical — recommended for HVAC technicians. Always disconnect power and gas before servicing, and diagnose the cause of any trip.
