EBR86093712 LG OEM Refrigerator Main Control Board Replacement

What Is the EBR86093712 LG Refrigerator Main Control Board Replacement? The EBR86093712 is the genuine OEM main control board for LG refrigerators, mounted behind an access panel on the back of the cabinet near the compressor compartment. This replacement control board manages compressor operation, fan control, temperature regulation, and the defrost cycle that keep your food cold. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA. What Does the EBR86093712 Fix on a LG Refrigerator? If your refrigerator is showing any of these problems, a failing main control board is a likely cause: Refrigerator not cooling or running too warm or too cold Control panel unresponsive or acting erratic Evaporator or condenser fan not running No power to the refrigerator at all Compressor starting and stopping on its own Error codes showing up on the display These symptoms point to the refrigerator control board as the most likely cause - but appliances are complex systems, and the same symptoms can occasionally stem from a sensor, switch, wiring harness, or motor issue. If a technician has identified the control board, or you've ruled out those components yourself, this board is your fix. When in doubt, contact us before you order - we're happy to walk you through some troubleshooting, and a photo of your board is usually all we need. A diagnosis from a local appliance technician works too. How Do I Know If This Is the Right Board for My Refrigerator? Before you order, match the number on your original board rather than just the refrigerator's model number. Unplug the fridge, pull it out, and remove the rear access panel to find the board's sticker. If that sticker reads EBR86093712, this is your board. Your LG refrigerator part number is on the sticker on the original board - look for the EBR or CSP prefix. Not sure? Send us a photo of your board and its sticker before you order and we'll verify it for free - same business day. Compatible Refrigerator Models This board is ordered by part number, not by appliance model. Send us your full model number and a photo of your board's sticker and we will confirm fitment before you buy - same business day. This model list is for reference only. LG may change boards between production runs, so two appliances with the same model number can use different boards. Always order by the part number printed on your original board - it is the only identifier that decides.

Key Features Genuine OEM LG main control board - not an aftermarket copy Direct replacement for the board behind your rear access panel Controls compressor, fan, temperature, and defrost operation Minor cosmetic wear may be present due to prior installation - it does not affect performance Board Type and Function This board is the main power and control center for the refrigerator. It reads signals from the temperature sensors and decides when to run the compressor, cycle the evaporator and condenser fans, and trigger the defrost heater. It also drives the control panel display and processes any error codes the system reports. When this board fails, the refrigerator can lose cooling entirely or start behaving erratically even though individual parts like the fans and compressor are still good. Common LG Refrigerator Error Codes If your LG refrigerator is displaying an error code, the table below describes what it typically indicates. Codes marked ★ are most directly associated with main control board failure. These are general LG codes and can vary by your exact model. Always confirm the exact meaning in your model's owner's manual or service guide before ordering any part. Code What It Means ★ CO Communication failure between main control board and display board ★ Er CF / CF Condenser fan feedback signal error - board not receiving fan confirmation signal ★ 22 Compressor relay problem - board-managed compressor circuit fault ★ dH Defrost cycle timed out - evaporator did not reach target temperature within 1 hour Er FF Freezer evaporator fan failure - fan not circulating cold air in freezer Er rF Refrigerator evaporator fan failure - fan not circulating air on fresh food side Er FS Freezer temperature sensor failure Er rS / r2 Refrigerator temperature sensor failure - upper (rS) or lower (r2) section dS Defrost temperature sensor short or disconnection Er IF / IS / It Ice maker fan (IF), temperature sensor (IS), or motor (It) failure CH E / CL E Refrigerant leak detected - high-side (CH E) or low-side (CL E). Requires professional service OF F Demo mode active - cooling disabled. Not an error. Deactivate via control panel hold sequence Error code definitions vary by LG model series. Always confirm the exact meaning in your refrigerator's owner's manual or service guide before purchasing any part. ★ = Most directly associated with main control board failure How to Install a LG Refrigerator Main Control Board Start by unplugging the refrigerator and pulling it away from the wall so you can reach the rear access panel, usually held on with Phillips screws. Before disconnecting anything, take a photo of the wiring harness positions so you know exactly how to reconnect them. Use basic ESD precautions and handle the new board by its edges, pressing the locking tabs to release each harness connector rather than pulling on the wires. Seat the new board into its mounting tabs, plug the harnesses back in using your photo as a guide, and reinstall the cover panel. Most people finish this job in under 30 minutes with basic hand tools. Once it's buttoned up, give the refrigerator a few hours to reach temperature before judging whether the repair worked.
