EBR76723401 Genuine Inverter PCB Assembly for LG Appliances, Inverter Control Board

In an LG inverter appliance, the inverter PCB assembly is the board that powers and controls the compressor or motor, and EBR76723401 is a genuine LG board of that type. LG uses inverter boards in several appliance types, and our stock record doesn't say which one this board belongs to. The number printed on the label of your existing board is the most reliable way to confirm you have the right match.

What an LG inverter board does and how it fails

Rather than switching a compressor or motor fully on and off, an inverter board converts the incoming supply into a variable frequency output so the load runs at just the speed needed. When the board fails, the compressor or motor may not start at all, the appliance can display an inverter or communication error, or it may run briefly then stop. Burnt components, swollen capacitors or a scorched smell are visible clues. Supply problems, wiring faults and a seized compressor can all look like a board failure, so test properly before replacing it.

Handling and fitting the inverter PCB

Isolate power and allow time for the board's large capacitors to discharge, as inverter boards can hold a dangerous voltage after switch off. Photograph every connector and earth lead before you remove anything. Handle the new board by its edges to avoid static damage. Hard-wired units must be serviced by a licensed electrician or qualified technician.
