Lennox R22 Ignition Control Board
The main ignition control board oversees gas flow, the igniter and all the flame sensing devices. It has always been a vital electronic circuit board that, in most cases, has become a piece of the main circuit board instead of having two separate boards.
How can I tell if my Lennox ignition control board is not working properly?
- Any other problem connected to the system is looked at and turns out to be good
- The electrical signal from the home thermostat does not make it to the main control board
- Ignition sequence is unwilling to start at all
