This DIY repair guide explains how to replace the electronic control board in a window air conditioner. The control board is the "brains" of the window air conditioner. It monitors the temperature and turns on components such as the compressor and fan to cool the room to the temperature you set. If the electronic control board doesn't work, replace it with the manufacturer-approved window air conditioner part.
