Mitsubishi MSZ-A24NA Ignition Control Board
The main reason to have an ignition control board is that it regulates gas flow, the ignition timing and all the flame sensing devices. It has been a very important electronic circuit board that, over the years, has merged to become a piece of the main circuit board for safety reasons.
Easy warnings of a declining ignition control board
- Every other thing throughout the system checks out problem-free
