Lennox CB29M-51 Ignition Control Board
An ignition control board checks out gas flow, the ignition ignitor and all the flame sensing devices. It has always been a vital electronic circuit board that some manufacturers have decided to blend to be a major component of the main board instead of a separate board.
Some clues of a laboring major ignition board
- Every other device in the HVAC system is inspected and seems to be acceptable
- Signal from home thermostat does not reach the main control board
- HVAC ignition system does not begin no matter what
