The Goodman 10123535 Manual Reset Rollout Limit Switch is a genuine OEM safety component engineered for the GKS90905DXAE gas furnace and other compatible Goodman/Amana models. This red manual-reset switch monitors for flame rollout at the burner box and cuts power to the gas valve if temperatures exceed a safe threshold, protecting your heat exchanger and home from overheating. Because it requires a manual reset, it also alerts homeowners that a fault such as a blocked flue or dirty burners needs attention before the furnace will restart.
OEM vs. Generic: This is the factory-specified Goodman part, calibrated to the exact trip temperature your furnace's control board expects. Generic switches may fit physically but often trip early, trip late, or fail to reset reliably — a risk you should never take with a safety cutoff. Choosing OEM guarantees correct calibration, terminal spacing, and long-term durability.
Install difficulty: Easy (1/5). Turn off power and gas at the furnace, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Most homeowners complete this in under 15 minutes. If the switch trips again after replacement, have a licensed HVAC technician inspect the flue, heat exchanger, and burners for the underlying cause.
