It controls the speed of an inverter motor or compressor by adjusting the frequency of the power it supplies. LG has other inverter boards with numbers very close to this one, so check all the digits on your old board's label. The specific LG product and models aren't on file, and the number is the key to a correct match.\u003c\/p\u003e\n\u003ch2\u003eHow an LG inverter board shows it has failed\u003c\/h2\u003e\n\u003cp\u003eInverter faults often appear when the appliance tries to start the motor or compressor. You may hear relays click with nothing turning, see a fault code linked to the inverter or compressor, or find the safety switch or breaker trips as soon as it starts. Sometimes the unit runs at a single speed or stops under load. Look at the board for heat damage around the large power devices and electrolytic capacitors. If the supply voltage was the trigger, for example after a storm, check whether other parts were damaged as well.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine LG part EBR74138306\u003c\/li\u003e\n\u003cli\u003eInverter PCB assembly\u003c\/li\u003e\n\u003cli\u003eClose numbers in the series are different boards, match every digit\u003c\/li\u003e\n\u003cli\u003eLG product and models not on file\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitting the inverter PCB\u003c\/h2\u003e\n\u003cp\u003eSwitch off and isolate the supply, then wait for the capacitors to discharge before touching the board. If the unit is hard wired, have a licensed electrician do the work. Record the wiring, fit the board with all screws and insulating parts, and run the appliance through a full start and stop before closing it up.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eIs EBR74138306 interchangeable with EBR74138303 or EBR74138309?\u003c\/h3\u003e\u003cp\u003eDon't assume so. Boards in the same number series can differ in software, ratings or connectors. Order the number shown on your old board, or the one LG lists for your model.
