The 0130F00038 auxiliary limit switch is a genuine OEM Goodman safety control for the AMH80403ANAA furnace and compatible Goodman/Amana models. This light-blue-coded secondary limit provides backup overheat protection at the blower or burner-box area, cutting the burners if the primary limit or airflow system fails to keep temperatures in a safe range. If your furnace locks out on a secondary limit or the blower housing runs hot, this inexpensive switch is a common, essential replacement.
Like the primary limit, the light-blue color code identifies a specific trip temperature. Genuine OEM ensures the correct calibration and terminal layout. At this low price point, there is little reason to risk a generic on a safety device.
Very Easy (1/5) — Single mount with spade terminals. Power off first and verify the color/trip rating matches. Do not bypass. If it trips repeatedly, investigate airflow before assuming the switch is faulty.
