Goodman GCH90453BX Ignition Control Board
The main reason to have an ignition control board is that it keeps an eye on the natural gas, the ignition timing and all the flame sensing devices. It is an important electronic safety board that some manufacturers have decided to blend to be a standard part of the main board for the sake of being more efficient.
What happens when my main ignition board is not working properly?
- Communication from the main thermostat does not turn up at the main board
- Every other thing attached to the system is looked at and turns out to be OK
- Ignition cycle is unable to fire up when called upon
