Lennox CB28UH-048 Control Board
The control board is created to operate the gas valve, the ignition igniter, the flame sensor as well as the blower all at once. It is impossible for your furnace or air handler to even function lest this board is hooked up and is correctly configured. Be absolutely sure when choosing a control board due to variances between HVAC systems. The chosen circuit board will have to match part numbers both the brand and model of your Lennox CB28UH-048 unit.
