It is specifically designed for Aaon rooftop units and air handling systems, providing seamless integration and maintaining the original equipment manufacturer's performance standards. By restoring proper flame rectification, this sensor eliminates nuisance lockouts and ensures your commercial heating equipment operates at peak efficiency. Trust the Aaon R86790 for accurate gas furnace flame sensing and robust system protection.

• Precision Detection: The 1.75" deep probe provides accurate flame rectification to prevent system failures.
• OEM Reliability: Genuine Aaon replacement part ensures perfect fitment and original factory performance.
• Enhanced Safety: Immediately detects flame loss to prevent unburned gas from entering the heat exchanger.
• Durability: Engineered with specialized alloys to resist carbon buildup and thermal degradation.

How do I know if my Aaon flame sensor needs cleaning or replacement?
If your HVAC unit starts and then shuts down after a few seconds (short-cycling), the Aaon R86790 may be dirty or failing to send the proper microamp signal to the controller.

Is the Aaon R86790 compatible with all Aaon rooftop units?
While this 1.75-inch flame probe fits many models, you should verify compatibility using your specific unit's serial number and the Aaon parts catalog.

Can I install this flame sensor myself?
Due to the technical nature of gas furnace flame sensing and safety requirements, installation by a licensed HVAC technician is highly recommended.
