The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM thermal safety control for the AMVC80804CNBD gas furnace and compatible Goodman/Amana models. This auxiliary (rollout/high-limit) switch is a normally-closed thermal cutout that opens and de-energizes the gas valve if the furnace exceeds a safe temperature — protecting the heat exchanger and blower compartment from overheating caused by a blocked filter, failed blower, or restricted airflow.
The color code (light blue) corresponds to a specific temperature trip point — installing a generic switch with the wrong rating can cause nuisance trips or, worse, fail to protect the furnace. This genuine OEM switch guarantees the correct set point, terminal spacing, and mounting hole pattern for a true drop-in fit.
Easy (1 of 5). Disconnect furnace power, note the wire positions, remove the two mounting screws, transfer the spade connectors, and secure the new switch. Under 15 minutes for most DIYers. Confirm the blue color match before ordering — furnaces use several limit switches at different set points.
