International Comfort Products T8DNL050B12B1 Ignition Control Board
An ignition control board has control over the main gas intake valve, the ignition sequence 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 its own individual board.
Key clues of an inadequate main ignition board
- The electrical signal from the primary thermostat never turns up at the International Comfort Products control board
- Initial ignition sequence is unwilling to initiate when it is supposed to
- Any other device within the system is inspected and seems to be in fine condition
