Lennox CB30U-46 Ignition Control Board
The main ignition control board checks the main gas intake valve, the ignition timing and other important devices. It has always been a vital safety feature that, in most cases, has become a part of the main control board in order to have better control over the system.
How do you know when your Lennox ignition control board is on its last leg?
- Any other potential problem in the heating and cooling system is inspected and seems to be all right
- The main ignition cycle declines to start then the thermostat send a signal
- The initial signal from the home thermostat never does reach the control board
