International Comfort Products NDN5050BFA1 Ignition Control Board
The purpose of the ignition control board is that it governs the gas valve, the ignition ignitor and other important devices. It is an important electronic circuit board that is usually a major component of the main board instead of having two separate boards.
Key clues of an inadequate chief ignition control board
