The LG EBR85130504 Dryer Main PCB Assembly is designed to restore proper electronic control and operation in compatible LG dryers. This replacement main control board regulates key drying functions by processing input from sensors and user controls, then managing components such as the motor, heater, and cycle settings. Installed inside the dryer's control compartment, it connects to the existing wiring harnesses and integrates with the appliance's electrical system for proper communication between components. By coordinating essential operating functions and supporting accurate cycle management, this assembly assists in maintaining consistent drying performance, reliable system operation, and proper response to selected program settings.
