The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM rollout/high-limit safety control designed for the Amana AMVC80804CXCA two-stage variable-speed 80% AFUE gas furnace and compatible Goodman/Amana models. This normally-closed switch monitors for flame rollout or blocked-flue overheating and shuts down the burners if a fault occurs — its manual reset button ensures the furnace stays offline until a technician inspects the cause.
Genuine OEM 10123529 switches are calibrated to the exact trip temperature specified by Goodman, so they protect your heat exchanger without nuisance tripping. Generic aftermarket switches may vary in trip point and mounting geometry, risking either false shutdowns or delayed protection. For a critical safety component, we recommend the OEM part.
Easy (1/5). Two-wire connection and a single mounting screw or clip. Always cut power at the disconnect before servicing. Because this is a safety limit, verify the underlying cause of any trip before resetting.
