The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM safety component engineered for the AMS951155DXAB gas furnace and interchangeable Goodman/Amana 95% single-stage models. This high-limit/rollout switch monitors heat-exchanger and burner-area temperatures, opening the circuit to shut down the furnace if it detects an overheat or flame-rollout condition. Because it is a manual reset switch, it must be physically reset after a trip — a deliberate design that forces a technician to inspect the cause before the unit restarts.
This is a factory-genuine Goodman OEM switch with the exact trip temperature and terminal configuration your furnace's control board expects. Generic aftermarket switches often use approximate trip points that can cause nuisance lockouts or, worse, fail to trip at the correct threshold. For a safety-critical limit switch, OEM is strongly recommended.
Easy (2/5) — Typically two spade terminals and one or two mounting screws. Always disconnect power before servicing. If the switch has tripped, diagnose the root cause (blocked flue, dirty filter, cracked heat exchanger) before returning the unit to service.
