Lennox XP19-030 Ignition Control Board
The main reason to have an ignition control board is that it regulates the natural gas, the ignition timing as well as other safety devices. The ignition control board was always an important device that, over the years, has merged to become a piece of the main circuit board instead of having two separate boards.
How do you know if your chief ignition control board is not working right?
- The primary ignition sequence can not fire up even though it is supposed to
- Every other potential issue in the system is inspected and turns out to be swell
- The electrical signal from the primary thermostat does not show up at the control board
