Haier CPN12XC9-E Ignition Control Board
The main reason to have an ignition control board is that it governs gas intake, the igniter and some other sensors. It is an important safety device that has now become a part of the main control board for safety reasons.
Some warnings of a dying ignition board
- The on-signal from the thermostat never makes it to the Haier control board
- Any other device in the system is researched and comes to be in good health
- Ignition sequence fails to activate even when called upon
