Lennox OF25-120R Ignition Control Board
Another safety feature is the ignition control board, which has control over gas intake, the ignition timing and a few other devices. It has been a very important electronic circuit board that is now usually a major component of the main board instead of a separate board.
What are the indications that my major ignition board is almost dead?
- The ignition cycle will not kick in at all
- The electrical signal from the home thermostat never moves to the Lennox control board
- Any other device connected to the system checks out okay

If you decide on picking up or ordering, do your due diligence and cross-check the correct model as well as make a visual inspection so that you are positive that the right ignition control board is the one being purchased. You do not need to install the part by yourself. Hire a pro in your community to replace the part.
Feel free to download your manual for help.
