The Goodman 10123532 is a genuine OEM manual-reset high-limit switch built for WGGE4360A090MAB gas furnaces. This safety control monitors heat-exchanger and plenum temperature and opens the circuit if the furnace overheats — most often from restricted airflow, a dirty filter, or blower failure. Because it is a manual reset device, it stays open until a technician presses the button, forcing the underlying cause to be found before the furnace can fire again. That is exactly what protects the heat exchanger from cracking.
The OEM 10123532 is calibrated to the exact trip temperature the WGGE furnace was engineered for. Generic limit switches with the wrong set point either nuisance-trip (short cycling) or fail to trip when they should — a genuine safety risk. Matching mounting bracket and terminal orientation also means no wiring modifications. For a life-safety component, OEM is strongly recommended.
Rating: Easy to Moderate. Power off at the disconnect, remove two mounting screws, transfer the spade terminals, and reinstall. Typically 15–20 minutes with a nut driver. Never bypass or jump a limit switch — if it keeps tripping, diagnose the airflow or blower problem first.
