Lennox Elite 14 Ignition Control Board
The main reason to have an ignition control board is that it has control over the main gas intake valve, the igniter and some more sensing equipment. It is an important electronic safety board that, in most cases, has become a major component of the main board for the sake of being more efficient.
Some clues the ignition board needs replacing
- Any other potential problem in the HVAC system is inspected and seems to be OK
- The main ignition cycle will not start no matter what
- The initial signal from the home thermostat does not get to the control board
