The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM thermal safety control for the ACVC80805CXCA gas furnace. This normally-closed limit switch opens when it senses excessive temperature — typically from restricted airflow, a dirty filter, or blower failure — and shuts down the burners to protect the heat exchanger and surrounding components from overheating.
Limit switches are calibrated to a specific trip temperature indicated by the light-blue color code. Installing the wrong rating — common with generic substitutes — can allow dangerous overheating or cause nuisance shutdowns. Always match the OEM part to ensure correct protection.
Easy. Two mounting screws and two push-on terminals. Cut power, replace, and confirm the switch resets after cooldown. A quick repair for most homeowners.
