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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20269903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary Limit \/ Auto-Reset Safety Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (self-resetting on cooldown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Backup overheat \/ rollout protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman WGGE4530A090MAA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM auxiliary limit\u003c\/strong\u003e is set to the factory trip temperature and reset differential for the WGGE4530A090MAA.
