Lennox XC15 Ignition Control Board
The ignition control board is a safety device that governs the gas valve, the igniter and other important devices. It has been a very important safety device that is now usually a standard part of the main board instead of a separate board.
Warnings your main ignition board is dead
- HVAC ignition cycle declines to fire up when it is supposed to
- Every other device attached to the system is explored and ends up being okay
- The electrical signal from the home thermostat does not get to the control board
