EBR63372205 Genuine Main PCB Assembly with EPROM for LG Appliances, LG Main Control Board Replacement

Part EBR63372205 is a genuine LG main PCB assembly supplied with its EPROM, the memory chip that holds operating data for the board. LG often makes several versions of a main board that look alike, so the full part number is what counts. We don't have a model list or appliance type on file for this board, so please match the number on the sticker of your old board, or send us the model and serial numbers before ordering.

Signs the main control board has failed

The main PCB is the brain of the appliance. It reads sensors and user inputs, then switches the motors, valves, heaters or compressor that do the work. A failed board can leave the appliance completely dead, stuck on an error code, unresponsive to the remote or buttons, or running parts at the wrong time. Burn marks, a swollen capacitor, a blown fuse on the board or a burnt smell are strong signs. Power surges, insects and moisture are common causes, so check what damaged the old board before fitting the new one.

Fitting a main PCB

Isolate the appliance at the switchboard or unplug it, then wait several minutes for stored charge to drain before touching the board. Hard-wired units must be worked on by a licensed electrician. Photograph every connector and its position, transfer any jumpers or settings from the old board if your model needs it, and handle the new board by its edges. Test all functions once it's back together.

Questions about this part

Why does it matter that this board comes with an EPROM?

The EPROM stores data the board needs to run the appliance correctly. A board supplied with its EPROM saves sourcing the chip separately. Fitting a board with the wrong data can cause errors or poor running, so always match the part number.
