International Comfort Products H8DNL125L20A1 Control Board
Your system definitely will not operate whatsoever lest the circuit board is in its proper place and configured for your unit. The control board is created to operate the gas valve, the igniter, most sensors as well as the blower all at once. Be absolutely sure while picking a new replacement board due to the vast differences in brands, models and types of systems. The brand of board you choose is supposed to have a part number that matches both the brand and model of your International Comfort Products H8DNL125L20A1 unit.
Red flags your main board should need replacing
- The power to the system has to be powered down and back up quite a lot for the furnace or AC to kick on
- The heating and cooling system is unable to do anything correctly
- There is lit up error code shown somewhere on the board
