The main PCB is the brain of the appliance, holding the program software and switching the motors, pumps, valves or heaters that do the work. Which LG product it suits isn't on file. If your old board carries the EBR78401710 label, this is the same part.\u003c\/p\u003e\n\u003ch2\u003eMain PCB trouble on LG appliances\u003c\/h2\u003e\n\u003cp\u003eA main PCB problem usually announces itself in one of a few ways. The appliance may show no signs of life at all, or it may light up but refuse to start a cycle. Some boards fail with a stuck relay, so a motor or heater keeps running when it shouldn't. Others throw a fault code that won't clear even after the related part has tested good. Inspect the board under good light for burnt resistors, bulging capacitors or a darkened area, all of which confirm the diagnosis.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine LG part EBR78401710\u003c\/li\u003e\n\u003cli\u003eMain PCB\u003c\/li\u003e\n\u003cli\u003eLG appliance and models not on file\u003c\/li\u003e\n\u003cli\u003eSimilar LG main board numbers exist, check every digit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSwapping in the new main PCB\u003c\/h2\u003e\n\u003cp\u003eTurn the appliance off at the wall and unplug it before opening it up, or have a licensed electrician isolate a hard-wired unit.
