Nordyne E3EX-010H Ignition Control Board
The main reason to have an ignition control board is that it checks out gas flow, the ignition timing and other safety devices built into the system. It is an important safety feature that, in most cases, has become a vital part of the main control board for enhanced safety.
What to see if the major ignition board needs replacing?
- Any other device in the HVAC system is looked at and turns out to be just fine
- The main ignition cycle fails to initiate no matter what
- The electrical signal from the main thermostat never reaches the main control board
