Lennox HPXB15-024 Ignition Control Board
An ignition control board has control over the natural gas, the ignition ignitor as well as other safety devices. The ignition control board was always an important electronic safety board that is now usually a vital part of the main control board instead of a separate board.
Simple warnings that your chief ignition control board is about to go out?
- The electrical signal from the thermostat never does reach the control board
- Every other thing throughout the system checks out good
- The primary ignition sequence fails to start at all
