Lennox 16V29 Ignition Blower Control Board

The Lennox 16V29 Ignition Blower Control is the component of the operation in a Lennox gas furnace startup sequence. This small printed circuit board controls the first part of the heating process and provides a safe ignition. This is similar to the conductor which sequentially distributes electrical power. First, it switches on the blower motor to clear out any remaining gas for safety reasons. Then, it initiates the ignition system to burners and starts the heating process for further production.
