International Comfort Products H9MPD100J14B1 Control Board
It is impossible for your furnace or air handler to even operate unless the control board is hooked up and is correctly configured. The control board is made to control the gas valve, the ignition igniter, all the sensors and the blower all together. The selected board should match the model number with both the make and model of your heating and cooling system. Be absolutely sure when you decide to replace your control board because of the diversity of HVAC systems.
Simple warnings that your main board needs replacing?
- Power to the control board has to be turned off and back on many times a week for the thermostat to kick in
- The furnace or AC is unable to function whatsoever
- When turned on, there is some sort of code directly on the front of the control board
