International Comfort Products T8MPL125J20B1 Ignition Control Board
An ignition control board controls gas flow, the igniter and some other sensors. It has been a very important safety feature that has now become a part of the main control board instead of its own individual board.
How can I tell if my chief ignition control board is almost dead?
- The ignition cycle declines to activate even when the thermostat kicks it on
- Any other device within the furnace checked out to be fine
- Communication from the main thermostat never makes it to the main control board
