The LG EBR80198607 Dryer PCB Main-Control Board is used to manage and coordinate the dryer’s primary electronic functions for proper cycle operation. This printed circuit board assembly receives signals from the dryer’s controls and sensors and processes them to operate functions such as drum rotation, heating, cycle timing, and selected drying settings. As the main electronic control, it communicates with different components to maintain the programmed sequence of operation. A faulty control board may cause unresponsive controls, heating issues, incorrect cycle performance, or interrupted drying. Replacing the board can restore normal electronic operation and proper cycle control.
