International Comfort Products H8DNL075B12B1 Ignition Control Board
The purpose of the ignition control board is that it may control the natural gas, the ignition timing and the flame sensing circuits. It has always been a vital circuit board that is now usually a vital part of the main control board instead of a separate board.
What are some indications that my ignition control board is in need of a replacement?
- Signal from primary thermostat never reaches the control board
- HVAC ignition system declines to fire up when it receives a proper signal
- Everything else in the HVAC system is researched and comes to be in good health
