EBR37094713 Genuine Inverter PCB Assembly for LG Appliances, LG Inverter Control Board Replacement

EBR37094713 is a genuine LG inverter PCB assembly. An inverter board drives a motor or compressor at variable speed instead of simply switching it on and off, which is how LG inverter appliances save energy and run more quietly. We don't have the appliance or models on file for this board, so please match EBR37094713 to the sticker on your old inverter board before ordering.

Inverter board faults and what they look like

The inverter board takes a DC supply and turns it into a variable frequency output to run the compressor or motor at the speed the main control asks for. It works hard and runs hot, so heat, power surges and ageing components are common causes of failure. Typical symptoms include a compressor or motor that won't start, starts then stops, runs at one speed only, or a unit that trips the power or shows an inverter or compressor error. A seized compressor or shorted motor can damage a new board, so have it tested before fitting.

Fitting the inverter board

Inverter boards hold large capacitors that can stay charged for some time after the power is off. Isolate the appliance, wait for the board to discharge and check it with a suitable tester before touching it. This is technician work, and hard-wired units need a licensed electrician. Refit thermal paste or pads under the heat sink as the old board had them, and tighten heat sink screws evenly.
