Heat Controller SMA 12 Control Board
The Heat Controller SMA 12 control board is constructed to command the gas valve, the igniter, most sensors and the blower all at once. Most systems will not operate lest the main control board is correctly installed. Be very careful upon picking a replacement board because of the diversity of HVAC systems. The control board you choose will need to pair with the part number from both the make and model of the unit in question.
