The Goodman 10123539 Manual Reset Rollout Limit Switch is a genuine OEM safety component engineered for the AMEC960804CNAD gas furnace and other compatible Goodman/Amana equipment. This switch monitors the burner box for flame rollout — a dangerous condition where flames escape the heat exchanger — and instantly cuts the gas valve and ignition circuit to protect your equipment and home. Because it is a manual reset device, it will not automatically re-close after a trip, forcing an inspection before the furnace can restart. A furnace that repeatedly trips this switch signals a blocked heat exchanger, a failing inducer, or a venting problem that should be corrected before resetting.
OEM vs. Generic: The OEM 10123539 is calibrated to the exact trip temperature specified for this furnace platform, ensuring it protects without nuisance shutdowns. Aftermarket switches may use looser tolerances that trip early or, worse, trip late. Choose OEM when safety-critical calibration matters.
Install difficulty: Easy (1/5). Shut off power and gas, unclip the two spade terminals, remove the mounting screws, swap the switch, and reconnect. Typically a 10–15 minute repair with a nut driver. Always diagnose the root cause of a rollout trip before returning the furnace to service.
