The Goodman 10123517 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the Goodman GCH950453BXAA gas furnace. Unlike auto-reset limits, this switch latches open when it trips and must be manually reset with its push button — a deliberate safety design that forces a technician or homeowner to investigate the overheat cause (blocked airflow, dirty filter, failed blower) before the furnace can run again.
This genuine Goodman OEM switch is calibrated to the exact trip and mounting spec of your furnace. Because it's a life-safety component, a generic substitute with a different trip temperature or bracket footprint is a false economy — the OEM part ensures correct protection and a proper fit.
Easy (2/5) — Cut power, remove the mounting screws, transfer the two wires, and reinstall. If the old switch keeps tripping, address the root airflow cause first. Around 20 minutes.
