Payne PY2PNB048130AA Ignition Control Board
The main reason to have an ignition control board is that it manages gas flow, the ignition ignitor and a few other devices. It is an important circuit board that, over the years, has merged to become a standard part of the main board instead of having two separate boards.
Indications to watch for in a bad ignition control board
- Every other thing in the heating and cooling system is explored and ends up being OK
- The initial signal from the home thermostat gets lost before it makes it to the main board
- HVAC ignition system will not activate even when the thermostat kicks it on
