Carrier 38YKC030 Ignition Control Board
The main reason to have an ignition control board is that it governs gas flow, the ignition sequence and other safety devices built into the system. It has been a very important device that is usually a major component of the main board instead of a separate board.
Subtle cues of a deteriorating chief ignition control board
- The main ignition cycle refuses to begin even though it is supposed to
- Every other problem throughout the system checks out all right
- The electrical signal from the remote thermostat never makes it to the main board
