Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset high-limit switch built for the Amana AMEC800603BNAB gas furnace and compatible Goodman/Amana models. This safety switch monitors furnace temperature and opens the control circuit to shut off the burners if it detects an overheat or flame-rollout condition, protecting the heat exchanger and household. Because it is a manual reset design, it must be pressed to reset after a trip — a repeated trip indicates an airflow or combustion fault that should be diagnosed. A failed limit switch can cause no-heat or unsafe operation, so a genuine replacement is critical.

OEM vs. Generic

Generic switches may differ in set-point or mounting, which can compromise protection. For a life-safety component, always use OEM.

Installation Difficulty

Easy (2/5). Typically a two-wire, two-screw replacement. Shut off power and gas first, and never bypass or defeat a limit switch. If the switch keeps tripping, have a licensed HVAC technician diagnose the underlying cause.
