The Goodman 0130F00038 is a genuine OEM auxiliary limit switch, color-coded light blue to indicate its specific trip temperature. Designed for the ADSH800804BXAA furnace and compatible Goodman/Amana models, this secondary safety switch provides an additional layer of overheat protection beyond the primary high-limit. Auxiliary limits are typically mounted near the blower compartment or secondary heat-exchanger area to guard against localized overheating, opening the control circuit to shut the furnace down before damage occurs.
The OEM Goodman 0130F00038 ensures the correct light-blue trip temperature and mounting fit for dependable secondary protection. Our generic equivalent matches the same specifications at a lower cost — a smart option for out-of-warranty furnace repairs where safety specs are preserved.
Easy (1 of 3). Shut off power at the breaker, remove the mounting screws, swap the wire leads to the new switch, and remount. Verify the light-blue color code matches your original part before installation.
