International Comfort Products GDJ125M20A1 Control Board
The International Comfort Products GDJ125M20A1 control board is designed to control everything including the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. It is impossible for your furnace or air handler to even be able to function without the board in its proper place and configured for your unit. A control board that you have chosen must be compatible with the brand and the model of air handler system you have. Be very careful when you are choosing a replacement board because of the diversity of models within certain brands.
Signals of an ineffective control board
- The system board has to be reset habitually for the heating or cooling to kick in
- The whole unit declines to function well
- There may be a strange code indicated on the control board
