International Comfort Products NAC018GKA1 Ignition Control Board
The ignition control board is a safety device that checks out gas intake, the ignition ignitor and all the flame sensing devices. It has been a very important electronic safety board that some manufacturers have decided to blend to be a part of the main control board for safety reasons.
Clues of a bad major ignition board
- The electrical signal from the home thermostat never reaches the control board
- Any other device in the heating and cooling system is inspected and seems to be flawless
- HVAC ignition system does not commence at all
