Lennox G40UH-24A-045X Ignition Control Board
An ignition control board has control over the gas valve, the ignition timing and all the flame sensing devices. It has been a very important circuit board that is now usually a standard part of the main board for enhanced safety.
What are some hints that my Lennox ignition control board has a need to be replaced?
- The ignition cycle is unwilling to launch even though it is supposed to
- Everything else attached to the system is inspected and turns out to be problem-free
- The electrical signal from the thermostat never reaches the control board
