The 0130F00038 is a genuine Goodman/Amana auxiliary (secondary) high-limit switch designed for the AMH80804BNAA 80,000 BTU gas furnace and compatible multi-position models. Identified by its light-blue housing, this normally-closed thermal switch monitors heat-exchanger and cabinet temperature, opening the burner circuit if the unit overheats due to restricted airflow, a failed blower, or a dirty filter. It is a critical safety component — a furnace should never be operated with a bypassed or missing limit control.
This is a factory OEM Goodman part, calibrated to the exact trip temperature specified for your furnace. Generic universal limits may carry a different set point, which can cause nuisance trips or, worse, fail to protect the heat exchanger. For a safety control, matching the OEM calibration is strongly recommended.
Rated Easy — a two-wire, single-fastener swap for anyone comfortable working inside a furnace. Always shut off gas and electric power before servicing. If you are unsure why the original limit failed, have a licensed HVAC technician diagnose the airflow issue before replacing.
