International Comfort Products T9MPD075F12C1 Control Board
The control board is constructed to operate the gas valve, the ignition igniter, all the sensors and the blower all in one unit. Your system definitely will not run at all unless the control board is configured and seated properly. The chosen circuit board is supposed to have a part number that matches both the brand and specific model of your particular system. Be very careful when you are choosing a replacement board because of the many variances of HVAC systems.
Red flags your main board will die soon
- There may be some sort of code revealed on the front of the control board
- The AC or furnace does not initialize at all
- Power to the circuit board needs to be reset habitually for the system to continue working
