Furnace Control Boards
Furnace control boards are circuit boards designed to control heating units in HVAC systems. There are 2 types of gas furnace control boards. The first type is a simple ignition control that controls the gas valve, the ignitor and a flame sensing circuit. This type of control is typically found in older units that are not particularly energy efficient. The other type of furnace circuit board is an integrated furnace control. These controls perform additional duties because they also control the furnace blower in both the air conditioning and heating modes.
