Product details
This genuine LG part, EBR78401707, is a main PCB assembly. LG describes it as PCB Assembly, Main, the board that carries the appliance's control program and drives most of its other parts. A similar board, EBR78401710, is listed separately, so check the last three digits carefully. We don't have the appliance type or models on file, so please confirm using the label on your old board or your model's parts list.
Clues that point to the main PCB
When the main PCB fails, the appliance often looks completely dead, or it powers up but won't start a cycle, ignores some buttons or shows an error that keeps coming back. Faults can be intermittent at first, appearing only when the board warms up or after the appliance has been off for a while. Before replacing the board, check incoming power, fuses, door or lid switches and the plugs on the board itself. Signs of burning, corrosion or liquid on the board make the diagnosis much clearer.

Fitting the main PCB
Disconnect the power and allow a few minutes for stored energy to drain. Products on fixed wiring need a licensed electrician. Work on a dry, clean surface, keep the new board in its anti-static bag until you're ready, and transfer any jumper, switch setting or plug-in module from the old board if your model uses one. Reassemble fully before testing.
Questions about this part
Why is my old board a slightly different number?
LG updates boards over time, and a newer number may replace an older one for some models only. Don't assume a close number fits. Send us your model and the number on your old board through the parts enquiry form and we'll check what LG lists for your product.
