The Goodman 10123529 is a genuine OEM manual reset limit switch built for Amana/Goodman gas furnaces such as the AMEC800805CXAA. This safety control opens the circuit if the furnace overheats or a flame rollout occurs, shutting down the burners to protect the heat exchanger and your home. Because it is a manual reset device, it must be physically reset after tripping — a deliberate safeguard that flags a recurring problem instead of silently cycling.

OEM vs. Generic

Limit switches are calibrated to a specific trip temperature. This genuine OEM switch is set to the factory spec for your furnace, so it protects at the correct threshold. A mismatched generic switch can trip prematurely (no heat) or, worse, fail to trip when needed. For a safety component, always use the exact OEM part.

Install Difficulty

Easy. Disconnect power, remove the two mounting screws and the wire connectors, and install the replacement in the same orientation. Typically a 15-minute job. If your switch keeps tripping after replacement, have a technician inspect airflow and the heat exchanger.

Turn off electrical power before servicing. Verify the part number against your unit before ordering.
