The 0130F00038 Auxiliary Limit Switch is a genuine OEM temperature-sensing safety control for the Goodman/Amana AMS80403AXAB gas furnace and compatible models. Identified by its light-blue body, this auxiliary limit opens the control circuit and shuts the furnace down if temperatures exceed its rated trip point — protecting the heat exchanger and cabinet from damage caused by restricted airflow, a dirty filter, or blower failure.
Limit switches are color- and value-coded to a specific trip temperature. Installing a generic switch with the wrong rating can either nuisance-trip a healthy furnace or, worse, fail to protect it. The genuine Goodman 0130F00038 guarantees the exact factory trip point — never substitute by appearance alone.
Rating: Easy. With power off, remove the two mounting screws, transfer the wire terminals, and reinstall in the same location and orientation. About 10–15 minutes. Confirm airflow and filter condition, since repeat trips usually signal an underlying airflow problem.
Genuine OEM Goodman replacement, fitment guaranteed.
