The main PCB is typically located in the rear of the refrigerator or behind the control panel.

Shake it: if it rattles, it’s failed. Replacing the relay takes 5 minutes and no tools. If the relay is good and the compressor still won’t run, then the main board is the correct next step. Skipping this check is the most common reason customers replace a $380 board when a $20 relay was the actual problem.\u003c\/div\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":50332126675233,"sku":"EBR81182790","price":380.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/LG_Refrigerator_Main_Control_Board_EBR81182790_Restore_Full_Refrigerator_Operation.png?v=1782760604","url":"https:\/\/xpartsupply.com\/products\/lg-ebr81182790-main-pcb-assembly","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
