The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM high-limit safety control for GCH91155DXAB gas furnaces. This normally-closed switch interrupts the gas/ignition circuit when it senses an overheat or flame-rollout event, safeguarding the heat exchanger and cabinet. As a manual reset component, it must be reset by hand after tripping, ensuring the technician or homeowner addresses the cause rather than allowing repeated automatic cycling.

OEM vs. Generic

This genuine OEM switch is factory-calibrated to the correct trip temperature and bracket footprint for your model. The 10123519 and its sibling 10123517 differ in trip setpoint/location, so matching the exact OEM number is critical — generic substitutes can trip early or fail to protect. Choose OEM for correct, code-compliant safety behavior.

Install Difficulty: Easy

Rated Easy (1/5) — two mounting screws and two spade connectors. Shut off power and gas before service. If the switch keeps tripping, inspect airflow, the flue, and the blower before returning the furnace to service.
