OEM Goodman Auxiliary Limit Switch for ACVC960603BNAA — 0130F00038

Goodman 0130F00038 Auxiliary Limit Switch (Light Blue)

The genuine Goodman 0130F00038 auxiliary limit switch is the factory OEM secondary overheat safety for the ACVC960603BNAA 96% modulating gas furnace and related Goodman/Amana high-efficiency models. Marked by its light blue housing, this auxiliary limit guards a secondary zone of the furnace—such as the blower compartment or secondary heat exchanger area—and opens the control circuit on over-temperature to prevent damage when primary airflow is compromised.

OEM vs. Generic

Because each limit position on a Goodman furnace uses a specific trip temperature, the OEM Goodman auxiliary switch ensures the correct setpoint and the right physical fit. The light-blue color code distinguishes it from the purple primary limit—installing the wrong one can cause nuisance no-heat calls. At this price, genuine OEM is the obvious choice over uncertain generics.

Install Difficulty

Easy (15–20 minutes). Disconnect power, remove the two mounting screws, transfer the spade terminals, and mount the new switch. Confirm you are matching the light-blue auxiliary position. Resolve any restricted-airflow root cause before returning the furnace to service.
