The Goodman 0130F00038 is a genuine OEM auxiliary (high-limit) safety switch designed for the AMEC960403ANAA gas furnace and compatible Goodman/Amana models. This light-blue temperature limit control monitors heat-exchanger and blower-compartment temperatures, cutting power to the burners if the unit overheats. It is a critical safety component — a failed or open limit switch will prevent the furnace from firing or cause short-cycling on limit.
Our OEM option is the factory-specified switch with the exact temperature trip point and terminal configuration your furnace's board expects — the safest, drop-in choice. A generic equivalent can lower cost but may vary in trip temperature or lead length; always confirm the rating before substituting on a safety circuit.
Easy (2/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and swap in the new switch. Basic hand tools and 10–15 minutes for most DIYers. If unsure, consult a licensed HVAC technician.
