The ignition control board is a safety device that keeps an eye on gas flow, the ignition ignitor and other important devices. It has been a very important circuit board that some manufacturers have decided to blend to be a standard part of the main board instead of having two separate boards.
Easy warnings the major ignition board needs replacing
- Ignition cycle refuses to start even though it is supposed to
- The electrical signal from the remote thermostat never makes it to the main control board
- Every other potential issue in the system is inspected and seems to be in good health
