The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for WGGE4524A070MAA gas furnaces. This normally-closed switch opens and cuts the gas/ignition circuit if it senses an over-temperature or flame-rollout condition, and it must be manually reset after tripping. Because it requires a manual reset, a tripped switch signals an underlying problem — restricted airflow, a dirty filter, or a heat-exchanger issue — that should be diagnosed before resetting.
This OEM Goodman switch is factory-calibrated to the furnace's exact trip temperature. Generic limit switches with the wrong set point can nuisance-trip or, worse, fail to open when needed. As a life-safety component, the OEM part is strongly recommended.
Easy (1 of 5). A quick 10-15 minute replacement: shut off power and gas, remove the two mounting screws, transfer the wire terminals, and mount the new switch. Always identify and correct the root cause of any trip before returning the furnace to service.
