The main control board is located in the rear lower section of the refrigerator behind an access panel. Photograph all wire harness connections before disconnecting. Remove the mounting screws, swap the board, reconnect all harnesses in the original positions, and restore power.

When it fails, the compressor won’t start and the refrigerator stops cooling — identical symptoms to a failed control board. Shake the relay: if it rattles, it’s failed. Replace it before ordering the board. If the relay tests good and the compressor still won’t run, then the board is the next logical suspect.\n\u003c\/div\u003e\n\n\u003c!-- MODEL-SPECIFIC REPAIR PAGES --\u003e\n\u003ch2\u003e✓ Model-Specific Repair Pages\u003c\/h2\u003e\n\u003cdiv class=\"model-link-grid\"\u003e\n  \u003ca href=\"\/pages\/lg-refrigerator-lfx21960st-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003eLFX21960ST\u003c\/a\u003e\n  \u003ca href=\"\/pages\/lg-refrigerator-lfx25960sb-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003eLFX25960SB\u003c\/a\u003e\n  \u003ca href=\"\/pages\/lg-refrigerator-lfx25960st-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003eLFX25960ST\u003c\/a\u003e\n  \u003ca href=\"\/pages\/lg-refrigerator-lfx25960tt-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003eLFX25960TT\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577562600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577562600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577563600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577563600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577564600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577564600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577569600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577569600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577572600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577572600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577573600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577573600\u003c\/a\u003e\n  \u003ca href=\"\/pages\/kenmore-refrigerator-79577579600-parts\" style=\"display:inline-block;border:1px solid #cc0000;border-radius:20px;padding:5px 14px;font-size:13px;color:#cc0000;text-decoration:none;margin:4px;\"\u003e79577579600\u003c\/a\u003e\n\u003c\/div\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":50331842150689,"sku":"A944391G","price":241.12,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/EBR34917104_R01_C01.jpg?v=1726744143","url":"https:\/\/xpartsupply.com\/products\/lg-ebr34917104-refrigerator-main-control-board-pcb-assembly","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
