The Goodman 0130F00038 Auxiliary Limit Switch (Light Blue) is a genuine OEM thermal safety control for the ACVC801005CXAB furnace. This auxiliary limit provides secondary over-temperature protection — opening the control circuit if heat builds up beyond safe levels in its monitored zone. The light-blue color code identifies its specific trip temperature, so matching the OEM part is essential to maintain the furnace's designed safety margins.
The OEM Goodman switch is factory-set to the exact temperature represented by its light-blue code. Installing a generic limit with a different setpoint — or guessing the color match — can cause nuisance trips or, worse, fail to protect the furnace. For safety controls, always match the OEM part and color.
A two-wire, snap-in or single-fastener replacement that takes about 10–15 minutes. Disconnect power before servicing. Confirm the replacement's color code matches the original. If the switch continues to trip after replacement, have a licensed HVAC technician check airflow and the heat exchanger.
