Samsung AVMKC040CA0 Ignition Control Board
The purpose of the ignition control board is that it checks gas flow, the igniter and a few other devices. It is an important board that, over the years, has merged to become a vital part of the main control board instead of its own individual board.
Red flags of a bad major ignition board
- HVAC ignition cycle does not commence when it is supposed to
- Any other device in the HVAC system is looked at and turns out to be all right
- Signal from main thermostat gets lost before it makes it to the main board
