The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the ADVC80603BNBA gas furnace. This normally-closed switch opens the burner circuit if it senses excessive heat — from a blocked flue, failed blower, or dirty filter — protecting the heat exchanger and cabinet from overheating. Because it is a manual reset device, a tripped switch will not auto-restart, alerting the homeowner that a fault condition occurred and needs attention.
The genuine OEM Goodman switch is calibrated to the exact trip temperature the ADVC80603BNBA requires. Generic limit switches with a different set-point can nuisance-trip or, worse, fail to trip when needed. This is a life-safety component — always match the OEM temperature rating.
Easy (2/5). Power down the furnace, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. About 10–15 minutes. If the old switch tripped, diagnose the root cause (airflow, flue, blower) before returning the unit to service.
