An Lg circuit board is another term for Lg control board. These are the nerve centers of virtually all Lg appliances, from dishwashers to ovens. You might also see it referred to as an Lg pcb board. “PCB” stands for printed circuit board. Back in the day, electricians had to arrange and connect a vast network of wires and the finished product somewhat resembled a bird’s nest. Construction of an Lg pc board, however, is a far more elegant process, resulting in a more durable product. Instead of wires, the metallic circuit pathways are actually printed onto a plastic or fiberglass board, similar to the way a laser printer renders designs on paper. It’s actually pretty cool.
