The genuine Goodman 10123529 Manual Reset Limit Switch is the OEM high-temperature safety control for the ADVC80603BNBB gas furnace. This normally-closed switch opens the ignition circuit if it senses an over-temperature or flame-rollout condition, shutting the furnace down and requiring a manual reset to prevent unsafe operation. It is a critical safety component — never bypass or jumper it.
OEM vs. Generic: The Goodman switch is calibrated to the exact trip temperature this furnace's safety circuit was engineered around. Generic limit switches with the wrong trip point either nuisance-trip during normal heating or, worse, fail to open soon enough during a real fault. On a safety device, matching OEM calibration is non-negotiable.
Install difficulty: Easy. Two spade terminals and one or two mounting screws. Shut off gas and power, transfer the wires, and mount the new switch in the original location and orientation. If the switch keeps tripping after replacement, diagnose the underlying airflow or combustion fault before running the furnace.
