EBR37319509 Genuine Main PCB Assy for LG Appliances, LG Main Control PCB Replacement Board

Matching the number is the most important step when buying an LG board, and this one is EBR37319509, a genuine LG main PCB assy. LG often makes several boards for one range, each set up for different models or features. Since we don't have an appliance or model list for this number on file, check the sticker on your old board, or ask us, before you order.

Main board failure and how to spot it

The main board is where the appliance's program lives. It reads inputs from switches and sensors and drives everything else through relays and electronic switches. Signs of failure include no response at all, controls that freeze, functions that run when they shouldn't, loads that won't switch on, or error codes that don't clear when the suspect part is replaced. Heat and moisture are the usual enemies, so look for brown or blackened areas, corroded tracks and bulging capacitors. A board that smells burnt has almost certainly failed.

Before you swap the board

Isolate the power and let the appliance sit for a few minutes before opening it. Mains voltage boards should be fitted by a qualified technician, and hard-wired appliances by a licensed electrician. Take photos of the board and every connection from a couple of angles. Fix whatever caused the old board to fail, such as a leak, before fitting the new one.
