The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light blue housing) is a genuine OEM secondary high-limit control for the AMSS921005CNAA gas furnace. Mounted near the blower deck or heat exchanger, it provides a backup overheat cutoff that de-energizes the furnace if temperatures rise beyond safe limits — for example during a blower failure or severely restricted airflow. It works alongside the primary limit switch to keep the heating cycle within a safe operating window.

OEM vs. Generic

The color-coded housing corresponds to a specific trip temperature, so matching the genuine OEM part guarantees the correct calibration. Substituting a different-rated switch can cause premature shutdowns or leave the furnace under-protected. For a safety control, always match the OEM specification.

Installation Difficulty

Easy (2/5). Usually mounts with one or two screws and disconnects with spade terminals. Cut power and gas first. If this switch has been tripping, correct the root airflow or blower issue before restoring the furnace to service.
