International Comfort Products T8DNL100L20B1 Ignition Control Board
The ignition control board is a safety device that checks out the natural gas, the ignition timing and all the flame sensing devices. It has been a very important safety feature that some manufacturers have decided to blend to be a major component of the main board instead of a separate board.
Some warnings of a worsening International Comfort Products ignition control board
- Heating and cooling system refuses to commence even though it is supposed to
- Any other device in the HVAC system is inspected and seems to be acceptable
- The electrical signal from the home thermostat does not get to the main control board
