International Comfort Products MB20N2600A2 Ignition Control Board
The main ignition control board checks gas flow, the ignition ignitor and the flame sensing circuits. It is an important board that some companies have moved to be a major component of the main board in order to have better control over the system.
Major warnings of a bad ignition control board
- The ignition system does not fire up at all
- Every other thing connected to the system checks out flawless
