International Comfort Products H9MPX100L20A2 Control Board
The control board is designed to direct everything including the gas valve, the ignition igniter, all the various sensors and the blower all at once. The entire heating and cooling system will not activate unless this important circuit board is in place and connected. You must be sure while searching to pick up a replacement control board because of the many variances of models within certain brands. The control board you choose should match the brand and the model of your heating and cooling system.
Important clues of an inadequate primary control board
- System has a strange code instantly appearing somewhere on the circuit board
- Your HVAC unit will not initialize at all
- Everything has to be reset frequently in order to operate
