Lennox XP14-042 Ignition Control Board
Another safety feature is the ignition control board, which controls the gas valve, the ignition ignitor as well as other safety devices. The ignition control board was always an important device that, over the years, has merged to become a part of the main control board in order to have better control over the system.
Some clues of a worsening ignition board
- The electrical signal from the primary thermostat never moves to the main board
- Every other device within the furnace checked out to be in good health
- The ignition system will not commence when it receives a proper signal
