Amcor UCHW-H09AF2 Ignition Control Board
The ignition control board is a safety device that checks gas intake, the ignition ignitor and all the flame sensing devices. It has been a very important safety device that has now become a major component of the main board instead of having two separate boards.
General warnings of an unhealthy main ignition board
