The Goodman 10123533 Manual Reset Rollout Limit Switch is a genuine OEM safety control engineered for the Goodman GKS90453BXAF gas furnace and compatible GKS90 series models. This flame-rollout switch monitors the burner compartment and interrupts the ignition circuit if flame escapes the heat exchanger, protecting your equipment and home from unsafe operation. Because it requires a manual reset after tripping, it forces a technician-verified inspection before the furnace can restart — exactly as the manufacturer intended.
Our OEM Goodman switch is calibrated to the furnace's exact trip point and reset characteristics. Generic aftermarket switches may vary in trip temperature and reset force, risking nuisance trips or failure to protect. For a safety-critical component, we recommend the genuine OEM part.
Easy (1/5) — Disconnect power, unplug the two spade terminals, remove two screws, and swap. Typically a 10-minute job for a qualified technician. Always shut off gas and power before servicing.
