The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the ADSH800403AXAA gas furnace and compatible Goodman/Amana 80% AFUE models. This rollout/limit switch monitors heat exchanger and burner temperatures and trips to shut off the gas valve if it detects an unsafe high-temperature or flame-rollout condition. Because it is a manual-reset design, it must be physically reset after a fault — a deliberate safety feature that forces a technician to inspect the cause before the furnace runs again.

OEM vs. Generic

This is a factory OEM part built to the exact trip temperature and mounting spec of your furnace, ensuring correct safety response. Generic substitutes may use a different trip point or terminal layout, which can cause nuisance lockouts or unsafe operation. For a safety-critical limit switch, OEM is strongly recommended.

Installation Difficulty

Easy (2/5). Two wire connectors and one or two mounting screws. Always shut off power and gas before servicing. If the switch has tripped, diagnose the root cause (blocked flue, dirty filter, failed blower) before resetting.
