International Comfort Products GNE050B12G1 Ignition Control Board
The purpose of the ignition control board is that it manages gas flow, the ignition timing and a few other devices. It is an important safety feature that, in most cases, has become a piece of the main circuit board instead of its own individual board.
Indications of an ineffective major ignition board
- Initial ignition sequence is unwilling to activate even when called upon
- Every other potential issue in the HVAC system checks out problem-free
- The electrical signal from the main thermostat never turns up at the control board
