The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM safety control for the WGGE4530A090MAA gas furnace. This secondary (auxiliary) limit provides backup overheat and flame-rollout protection, opening the control circuit when temperatures exceed safe limits and automatically resetting once the furnace cools. Because it self-resets, it protects against transient overheating without requiring a manual reset — but repeated trips signal an airflow or combustion problem that should be investigated.
This genuine Goodman OEM auxiliary limit is set to the factory trip temperature and reset differential for the WGGE4530A090MAA. Substituting a generic switch with different ratings can defeat the safety function or cause nuisance lockouts. OEM guarantees correct calibration and terminal fit.
Rating: Easy (1.5/5). With power disconnected, remove the mounting screws, transfer the wiring, and secure the new switch. If the auxiliary limit trips repeatedly, have a technician check airflow, the heat exchanger, and combustion before returning the furnace to service.
Compatible with Goodman/Amana furnaces using this auxiliary limit switch. Confirm your model before ordering.
