International Comfort Products H8DNL075B12A1 Control Board
HVAC systems will not run unless this board is configured and seated properly. The International Comfort Products H8DNL075B12A1 control board is constructed to oversee everything including the gas valve, the igniter, the flame sensor as well as the air circulator all together. It is of utmost importance when you choose a replacement because of the many variances of models within certain brands. The proper control board will have to match part numbers both the make and model of the system you have installed.
What are some hints that my HVAC circuit board is almost going bad?
- System has lit up error code displayed on the control board
- Power to the circuit board has to be powered down and back up more often than not for it to run correctly
- Your HVAC unit is unwilling to operate whatsoever
