International Comfort Products H9MPV075F12B1 Control Board
The control board is constructed to direct the gas valve, the ignition igniter, the flame sensor as well as the blower all at once. Most systems will not operate without this vital piece of hardware is hooked up and is correctly configured. A matching board will have to be compatible with both the make and model of the unit in question. You must do some research upon choosing a board as a replacement because of the diversity of particular brands and their models.
Indications of an unhealthy primary control board
- There is some sort of code shown on the circuit board
- The whole system has to be reset all the time for it to run
- The entire system is unable to start period
