Whynter ARC-126MD Ignition Control Board
The main reason to have an ignition control board is that it oversees the main gas intake valve, the ignition sequence and a few other devices. It has always been a vital electronic circuit board that, in most cases, has become a standard part of the main board for safety reasons.
Major indications poorly running main ignition board
- The initial signal from the thermostat never does reach the main control board
- The primary ignition sequence declines to activate even when the thermostat kicks it on
- Every other thing connected to the system is looked at and turns out to be problem-free
