The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light-blue body) is a genuine OEM safety control for the AMEH801005CXAB gas furnace and compatible Goodman/Amana models. This auxiliary limit provides secondary over-temperature protection, opening the control circuit if heat builds up in the blower or burner area — a backstop to the primary limit that guards against overheating from restricted airflow or blower failure.
The color code on Goodman/Amana limits indicates the exact trip temperature — light blue must be matched precisely. Installing the wrong-rated limit causes nuisance trips or, worse, fails to protect the furnace. The genuine OEM 0130F00038 guarantees the correct set point and preserves warranty coverage.
Difficulty: Easy. Disconnect power, remove the access panel, unplug the two spade terminals, and replace the switch with its mounting screws. Confirm the color code matches before installing, and address any underlying airflow restriction that may have caused the original to trip.
