The 0130F00038 is a genuine OEM auxiliary (rollout/over-temperature) limit switch, identified by its light-blue housing, for the Amana AMH80805CNBA gas furnace. This normally-closed thermal switch opens if the furnace exceeds its safe operating temperature — for example during blower failure or restricted airflow — cutting the gas valve to protect the heat exchanger. A tripped or failed limit is a frequent cause of no-heat and lockout conditions.
Limit switches are color-coded to a specific trip temperature. Installing the correct light-blue OEM part guarantees the furnace shuts down at the temperature the manufacturer specified — a generic or wrong-rating switch can nuisance-trip or, worse, fail to protect the heat exchanger. Always match the color.
Power off, note wire positions, remove two mounting screws, transfer the spade connectors, and reinstall. Typical time: 10–15 minutes.
