The Goodman 0130F00038 auxiliary limit switch is a genuine OEM safety control designed for the AMVC81005CNBA gas furnace and compatible Goodman/Amana models. This light-blue rollout/limit switch monitors temperature in the blower or burner compartment and opens the control circuit if the furnace overheats — protecting the heat exchanger, wiring, and cabinet from thermal damage. A tripped or failed limit switch is a common cause of no-heat calls and intermittent shutdowns, and OEM replacement restores reliable overheat protection.
The OEM switch is calibrated to the exact factory trip temperature and mounting footprint, ensuring the furnace's safety logic behaves as engineered. A Generic substitute can lower cost but must be matched carefully to trip point and reset type. For a safety component, we recommend the OEM part to guarantee the correct temperature rating.
Easy (1 of 5). Disconnect power, remove the two mounting screws and the spade terminals, then install the replacement in the same orientation. Verify the switch's temperature stamp matches before powering up. Typically a 10–15 minute repair.
