Goodman GCV90905DXA-P1257805F Ignition Control Board
The ignition control board is a safety device that oversees gas intake, the igniter and the flame sensing circuits. It has been a very important electronic safety board that some companies have moved to be a standard part of the main board in order to have better control over the system.
What warnings are present when my main ignition board really needs to be replaced?
- Ignition cycle is unable to begin at all
- Every other potential issue attached to the system is inspected and seems to be swell
- The on-signal from the thermostat never makes contact with the main board
