The Goodman 10123535 Manual Reset Limit Switch is a genuine OEM safety control designed for the Goodman GMS950904CXA gas furnace and compatible models. This red manual-reset rollout switch monitors burner-area temperature and interrupts the ignition circuit if a flame rollout or blocked-flue condition is detected, protecting the heat exchanger and your home. Because it is a manual-reset device, it must be reset by hand after a trip — a deliberate safeguard that flags an underlying issue requiring inspection.

OEM vs. Generic

The OEM Goodman 10123535 is factory-calibrated to the exact trip temperature specified for your furnace, ensuring correct safety response and preserving warranty compliance. Generic universal limit switches may vary in trip point and bracket fit. For a safety-critical rollout control, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). Two spade terminals and one or two mounting screws. Always shut off power and gas before servicing. If the switch has tripped repeatedly, have a technician diagnose the root cause before reset.
