International Comfort Products C8DNL075B12B1 Control Board
HVAC systems will not run without the board hooked up and is correctly configured. The International Comfort Products C8DNL075B12B1 control board is constructed to operate the gas valve, the igniter, all the sensors and the blower all together. Be very careful while searching to pick up a replacement control board because of the wide variety of systems. A control board that you have chosen is supposed to have a part number that matches both the make and model of the unit in question.
Signals to watch for in a bad control board
- AC or heating system will not function well
- There may be a strange type of error code indicated on the control board
- The whole system has to be powered down and back up quite frequently for it to run correctly
