Panasonic CS-E9NKUAW Ignition Control Board
The main reason to have an ignition control board is that it oversees the main gas intake valve, the igniter and other safety devices built into the system. It is an important safety feature that some manufacturers have decided to blend to be a standard part of the main board instead of its own individual board.
Indications your ignition control board should be replaced
- The main ignition cycle declines to fire up when it is supposed to
- Every other device in the heating and cooling system is inspected and seems to be problem-free
- Initial communication from the remote thermostat never does reach the main board
