The genuine Goodman 10123529 Manual Reset Limit Switch is a factory high-limit safety control for the Amana/Goodman AMH80805CNAA 80% AFUE, 80,000 BTU gas furnace. This normally-closed switch opens the ignition circuit if it senses an overheat or flame-rollout condition, shutting down the burners to protect the heat exchanger. The manual reset button requires a technician to confirm and clear the fault before the furnace can restart — a critical safety feature.

OEM vs. Generic

The OEM Goodman limit switch is calibrated to the exact trip temperature specified for this furnace. A generic switch with the wrong setpoint can either nuisance-trip or, worse, fail to shut down during a real overheat. For a life-safety control, only genuine OEM is acceptable.

Installation Difficulty

Moderate — Recommended for a qualified technician. A repeatedly tripping limit indicates an underlying airflow or venting fault that must be diagnosed. Cut power, transfer the two spade terminals, and mount the switch in its original bracket location.
