Heat Controller B-VMH12FC-1 Control Board
Heating and cooling systems will not even operate lest this board is installed. The control board is created to operate everything including the gas valve, the ignition igniter, most sensors as well as the air circulator all at once. It is of utmost importance when you are choosing a replacement board because of the wide variety of certain brands. The correct control board will have to match part numbers the brand and the model of furnace or air handler you have.
How do you know if your main circuit board is not working properly?
- The unit declines to do anything well
- The power to the system has to be reset quite a lot for the heating or cooling to kick in
- When turned on, there is a strange code indicated on the front of the control board
