The Surelight control board is the brain of the system, managing all the important functions, so getting the correct one is crucial. Here’s what I learned during my search and what helped me make an informed decision.
Understanding the Lennox Surelight Control Board
First, I made sure I understood exactly what the Surelight control board does. It controls the ignition, safety checks, and overall operation of the furnace or HVAC unit. If your system is acting erratically, not igniting properly, or showing error codes, the control board might be the culprit.
Compatibility and Model Numbers
One of the most important steps I took was verifying the exact model number of my Lennox system and the control board.

Installation Considerations
Installing the control board requires some technical skills. Since it involves electrical components and safety sensors, I recommend either hiring a professional technician or following the Lennox installation manual carefully. I didn’t want to risk damaging the board or my system, so I had a licensed HVAC technician do the installation.
Price and Warranty
The price can vary depending on the model and retailer, but I found it helpful to compare prices while considering warranty coverage. Lennox typically offers a warranty on their control boards, which gave me confidence that the investment was protected.
Final Tips from My Experience
