International Comfort Products H9MPD075F12C2 Control Board
The control board is designed to direct everything including the gas valve, the ignition igniter, all the sensors as well as the blower all at once. HVAC systems will not run unless this important circuit board is installed as it should be according to the manufacturer. A control board that you have chosen must have a matching part number consistent with both the make and model of the system you have installed. Be very careful when you are choosing a replacement board because of the many variances of certain brands.
What red flags are there that my main circuit board is dying?
- Your system ceases to run well
- There may be a type of code indicated directly somewhere on the circuit board
- Power to the control board has to be turned off and back on many times a day for the system to continue working
