The Goodman 10123534 Manual Reset Limit Switch is the genuine OEM high-limit safety control for the ACES960804CNAA gas furnace. This normally-closed thermal cutout opens and shuts off the burners if it senses an overheat or flame-rollout condition — protecting the heat exchanger, wiring, and your home from unsafe temperatures.
Unlike an auto-reset limit, this is a manual reset device: once tripped it stays open until a technician presses the reset button, ensuring the underlying fault (blocked airflow, dirty filter, failed blower, or rollout) is investigated before the furnace fires again. A switch that trips repeatedly or will not reset should be replaced with this exact OEM part.
Limit switches are calibrated to a specific trip temperature. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to trip when needed. The OEM 10123534 carries the correct Goodman temperature rating and bracket geometry, so it mounts and protects exactly as the factory intended.
Moderate (2/5) — Two mounting screws and two spade terminals; roughly 15 minutes. Shut off power and gas, and confirm the airflow fault is corrected before resetting.
