International Comfort Products GDJ075M12B1 Control Board
The control board is designed to command the gas valve, the igniter, the flame sensor as well as the blower all together. The system will cease to run at all without the main control board in connected and operational. The board you select will need to be a match with your existing board and be compatible with both the brand and model of the system you have installed. Be absolutely sure upon choosing a board as a replacement due to differences in brands, models and types of systems.
Clues of an ineffective main circuit board
- System has a strange type of error code indicated directly on the control board
- The entire system has to be reset quite a lot for the thermostat to kick in
- Your HVAC unit is unwilling to run correctly
