The Goodman 10123535 is a genuine OEM red-button manual reset high-limit / rollout safety switch for the GMH950704CXAB gas furnace. The red cap identifies its specific trip temperature and mounting location, distinct from the companion 10123533 switch. This normally-closed thermal switch interrupts the ignition circuit on flame rollout or overheat, safeguarding the heat exchanger and burner assembly.
Color coding on Goodman limit switches indicates the calibrated cut-out temperature. Installing the wrong switch — or a generic without a matched trip point — causes false lockouts or defeats the safety. The OEM 10123535 guarantees the exact factory calibration and terminal layout for a plug-and-play fit.
Budget 20–30 minutes. Turn off gas and electrical power, photograph the wiring, remove the two spade connectors and mounting screws, and fit the new red switch in the identical position and orientation. Confirm the red-button part number against your furnace before ordering, since this model uses more than one limit switch. Persistent tripping warrants professional diagnosis of airflow or combustion issues.
