Lennox 10ACE-024 Ignition Control Board
The main reason to have an ignition control board is that it has control over the main gas intake valve, the ignition ignitor and a few other devices. It has been a very important circuit board that some companies have moved to be a part of the main control board for the sake of being more efficient.
What to see if the main ignition board is in need of replacing?
- The main ignition cycle is unwilling to commence when called upon
- Every other thing within the furnace is inspected and turns out to be OK
- The on-signal from the home thermostat never reaches the main board
