International Comfort Products C9MPD100J20A1 Control Board
The control board is constructed to command the gas valve, the ignition igniter, all the various sensors as well as the blower all at once. The system will cease to operate without the board in its proper place and configured for your unit. The brand of board you choose should match both the make and model of furnace or air handler you have. It is imperative that you select wisely when choosing a control board due to so many small differences in systems.
What are some hints that my primary control board is dying?
- There may be a flashing error code appearing on the control board
- Power to the control board needs to be reset often for it to work
