The Goodman 10123529 is a genuine OEM manual reset limit switch for the WGGE4542A115MAA gas furnace and compatible Goodman/Amana models. This is a safety-critical high-limit/overtemperature switch: it opens the control circuit and shuts down the furnace if it senses an abnormal temperature or flame rollout condition, protecting the heat exchanger and cabinet from overheating. Because it is a manual reset device, it must be physically reset with the red button after a fault — and a switch that will not reset or that trips repeatedly signals an underlying airflow or venting problem that should be diagnosed.

Part number: 10123529
Type: Manual reset high-limit / rollout safety switch
Function: Opens control circuit on overtemperature to shut down burners
Reset: Manual (push-button)
Fits: Goodman WGGE4542A115MAA and cross-referenced models

OEM vs. Generic: This switch is factory-set to the trip temperature specified for your furnace. Substituting a generic limit with a different set point defeats the engineered safety margin and can allow dangerous overheating or cause nuisance shutdowns. On a life-safety component, always use the OEM part with the correct trip rating.

Install difficulty: Easy (2/5). About 15 minutes with a nut driver. Turn off power and gas, note wire lead positions, remove the two mounting screws, transfer the leads to the new switch, and remount. Restore power and cycle the furnace to confirm normal operation. If the new switch trips, do not bypass it — investigate blocked airflow, a dirty filter, or a venting fault.

Safety note: Never jumper or defeat a limit switch. Contact info@nationalhvacparts.com if you need help confirming the correct part.
