Nordyne E3EX-017H Ignition Control Board
An ignition control board governs gas intake, the ignition ignitor and the flame sensing circuits. It is an important circuit board that, in most cases, has become a part of the main control board instead of having two separate boards.
What are some indications that my ignition control board is about to stop working?
- Any other potential problem in the heating and cooling system is researched and comes to be a-OK
- Initial communication from the thermostat does not reach the main board
- Ignition sequence is unable to begin when called upon
