The Goodman 0130F00038 Auxiliary Limit Switch is a genuine OEM safety control engineered for ACVM970804CNBA gas furnaces and compatible Goodman/Amana models. This light-blue auxiliary limit monitors heat-exchanger and blower-compartment temperatures, opening the circuit to the gas valve if the unit overheats due to restricted airflow, a dirty filter, or blower failure. Replacing a failed or out-of-spec limit restores safe, reliable furnace operation and prevents nuisance lockouts.
OEM vs. Generic: The OEM 0130F00038 is calibrated to the exact open/close temperature specified for your furnace, ensuring proper safety response and warranty compliance. Generic universal limits may have different trip points that cause premature shutdowns or fail to protect the heat exchanger. For a safety-critical control, OEM is strongly recommended.
Install Difficulty: Easy (1/5). Disconnect power, remove the two mounting screws, transfer the spade connectors to the new switch, and remount. Typical replacement takes under 15 minutes with basic hand tools. Always verify proper furnace cycling after installation.
