The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light blue housing) is a genuine OEM secondary high-temperature safety control for the Goodman/Amana WFM18070S4BXCB gas furnace. This thermal cutout guards a specific zone — such as the blower deck or burner box — and opens the control circuit if that area exceeds its rated temperature, protecting against flame rollout or blower-compartment overheating. The color-coded housing denotes its factory trip point, so matching the exact part is essential.

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the light-blue trip temperature specified for this furnace and matches the mounting footprint. Because the color code maps directly to a set point, generic substitutes risk nuisance trips or unsafe operation. OEM is the correct, safe choice.
