The LG EBR31002613 Dryer Main PCB Assembly regulates key electrical functions to support proper operation in compatible dryers. This printed circuit board acts as the central control component that processes signals from sensors and user input, then manages cycles, temperature levels, and timing during operation. It operates by distributing electrical commands to heating elements, motors, and other connected components according to the selected settings. Installed within the dryer’s control housing and connected through wiring harnesses, the board integrates with the appliance’s internal system. By coordinating these functions, the component assists in stable cycle control, supports accurate operation of other elements, and helps maintain consistent drying performance during typical use.
