The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM thermal safety control designed for the Amana/Goodman AMH80403ANBB gas furnace and compatible 80% AFUE models. This normally-closed high-limit switch monitors internal cabinet temperature and interrupts the burner circuit if the furnace overheats, protecting the heat exchanger and blower assembly from thermal damage.
OEM vs. Generic: The genuine OEM 0130F00038 is factory-calibrated to the exact trip temperature specified for your furnace — critical for a safety component. Aftermarket switches may carry a different trip rating that can cause nuisance shutdowns or, worse, fail to trip when needed. For limit and safety controls we recommend OEM.
Installation Difficulty: Easy (1/5). Two spade terminals and a single mounting screw. Always disconnect power at the breaker before servicing. If the switch is tripping repeatedly, inspect airflow and the heat exchanger — a bad limit switch is often a symptom of a restricted filter or blower fault.
