Lennox G40UH-36A-070X Ignition Control Board
The purpose of the ignition control board is that it checks the gas valve, the ignition timing and other important devices. It has been a very important electronic safety board that some manufacturers have decided to blend to be a piece of the main circuit board for safety reasons.
What are the clues to watch out for to know my major ignition board is about to go out?
- Initial ignition sequence declines to kick in when it receives a proper signal
- Every other potential issue within the heating and AC system is looked at and turns out to be swell
- Initial communication from the main thermostat never turns up at the main board
