The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control for the Amana/Goodman AMH80403ANBA gas furnace. This normally-closed thermal cutout opens when it senses abnormal heat — such as a blocked vent, failed blower, or restricted airflow — cutting power to the gas valve to prevent overheating and heat-exchanger damage.
Limit switches are color-coded to a specific trip temperature. The OEM light-blue 0130F00038 guarantees the exact cutout rating your furnace was engineered for. Generic switches may trip early (nuisance shutdowns) or late (unsafe). For a safety device, always match OEM.
Difficulty: Easy (1/5) — about 10 minutes. Disconnect power, remove two mounting screws, transfer the wire leads, and reinstall in the same orientation.
Confirmed fit for the AMH80403ANBA. Verify your part number before purchase.
