International Comfort Products H9MPD100J14C1 Control Board
The control board is made to direct everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. Most systems will not run at all without the board in connected and operational. The board that you will choose will need to be a match with your existing board and be compatible with both the brand and model of air handler system you have. Be absolutely sure upon choosing a board as a replacement due to differences in systems.
What happens when my HVAC circuit board really needs to be replaced?
- System is unable to operate well
- When turned on, there is a certain error code appearing somewhere on the board
- The system board needs to be reset many times a day in order to operate
