Lennox CB29M-26 Ignition Control Board
The purpose of the ignition control board is that it oversees the natural gas, the igniter and the flame sensing circuits. It has been a very important device that has now become a part of the main control board instead of a separate board.
Key clues of a faulty Lennox ignition control board
- Ignition sequence fails to initiate even when the thermostat kicks it on
- Everything else in the heating and cooling system is inspected and seems to be good
- The on-signal from the remote thermostat never makes it to the main control board
