The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control designed for the ACVC801005CXAB gas furnace and other compatible Goodman/Amana models. This switch monitors heat-exchanger temperature and opens the control circuit if the furnace overheats — protecting the equipment and your home from unsafe conditions. Because it is a manual reset device, it requires a deliberate button press to restore operation after a trip, prompting a service inspection rather than silent re-cycling.
This is the genuine OEM Goodman switch, factory-calibrated to the exact trip temperature your furnace expects. Aftermarket generics may carry a different setpoint or terminal layout, which can cause nuisance trips or improper protection. For a critical safety control, OEM is strongly recommended.
A two-wire, single-fastener replacement that most DIYers can complete in 10–15 minutes. Always shut off electrical power and gas supply before servicing. If the switch trips repeatedly after replacement, have a licensed HVAC technician inspect for airflow restriction or a cracked heat exchanger.
