Samsung UD18B1C2 Ignition Control Board
The purpose of the ignition control board is that it has control over the main gas intake valve, the ignition sequence and all the flame sensing devices. It has been a very important device that, over the years, has merged to become a vital part of the main control board instead of having two separate boards.
What to see if the ignition control board is dying?
- Heating and cooling system fails to kick in when called upon
- Any other device throughout the system is inspected and seems to be a-OK
- The initial signal from the remote thermostat gets lost before it makes it to the Samsung control board
