International Comfort Products H8DNL100F14B1 Ignition Control Board
The main ignition control board oversees the natural gas, the ignition timing and a few other devices. It has been a very important circuit board that, over the years, has merged to become a vital part of the main control board for safety reasons.
Some clues of a weakening ignition board
- Ignition cycle does not activate no matter what
- Every other potential issue throughout the system checks out in good condition
- The initial signal from the primary thermostat does not make it to the International Comfort Products control board
