Lennox XP19-042 Ignition Control Board
The main reason to have an ignition control board is that it controls the main gas intake valve, the igniter and other safety devices built into the system. It has been a very important electronic circuit board that is usually a piece of the main circuit board instead of having two separate boards.
Indications your ignition control board will not last the year
- The on-signal from the main thermostat never does reach the control board
- Initial ignition sequence can not initiate at all
- Any other potential problem within the system is inspected and turns out to be all right
