Heat Controller VMH12SC-1 Control Board
The Heat Controller VMH12SC-1 control board is constructed to command the gas valve, the igniter, the flame sensor as well as the air circulator all in one unit. The entire heating and cooling system will not activate lest the main control board is installed. It is imperative that you select wisely while choosing a new control board because of the many variances of HVAC systems. The chosen circuit board will have to match part numbers both the make and model of the unit you have installed.
Some clues your primary control board needs to be replaced
- Your system is unable to do anything at all
- There seems to be a type of code being displayed on the front of the control board
- Power to the control board needs to be reset frequently for it to run
