What Is the EBR86824107 LG Refrigerator Main Control Board Replacement?
The EBR86824107 is the genuine LG main control board for LG refrigerators, mounted behind an access panel on the cabinet - sometimes lower back or front, sometimes inside on a side wall or ceiling panel depending on the model. This replacement control board reads sensor data and coordinates the compressor, fans, and defrost cycle to keep temperatures steady in both compartments. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the EBR86824107 Fix on a LG Refrigerator?
This board is typically the fix when you see any of the following:
- Refrigerator not cooling or cooling unevenly
- Freezer or fridge temperature swings from one day to the next
- Control panel display frozen or slow to respond to button presses
- No power to the unit, or it starts and stops on its own
- Ice maker or water dispenser doesn't work when you select it
- Compressor cycling on and off more than it should
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?
Find the small sticker on the original board - it will carry the part number printed there. Pull the access panel, locate the board, and compare that number directly against EBR86824107. If it matches, this is your board. Your LG refrigerator part number is on the sticker on the original board - look for the EBR or CSP prefix.

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
- Directly controls compressor, fan, and defrost operation
- Processes sensor input to regulate fridge and freezer temperature
- Minor cosmetic wear may be present due to prior installation - it does not affect performance
Board Type and Function
This main control board is the central PCB assembly running the refrigerator's cooling system. It takes readings from temperature sensors and uses them to manage compressor cycling, fan speed, and the defrost schedule. When the board fails or misreads sensor input, you get the cooling and temperature problems this part is meant to correct. It's the single component responsible for keeping the compressor, fans, and defrost heater working in sync.
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.

How to Install a LG Refrigerator Main Control Board
Start by cutting power to the refrigerator at the wall. Remove the Phillips screws holding the access panel in place and set the cover aside to expose the board. Before touching any wires, take a photo of the harness connections so you know exactly where each one goes back. Press the locking tabs to release each connector from the old board, then pull it free from the mounting tabs - handle it by the edges and ground yourself first to avoid static damage. Seat the new board into the mounting tabs, reconnect each harness connector in its original spot until it clicks, then reinstall the access panel and restore power. Most people finish this in under 30 minutes, but give the unit a few hours to settle into its temperature cycle before judging whether the repair worked.
Shipping
Every board is physically in stock - no backorders, no drop shipping. Orders placed before 4:00 PM EST ship the same business day. Tracking provided on every order.
Warranty
Backed by a 1-year warranty from Appliance Pro USA (registration required - the card is in the box). If the board fails due to a defect within the warranty period, we'll repair or replace it at no charge (shipping fees may apply). Warranty coverage is determined at Appliance Pro USA's discretion. Boards that have been tampered with, or with the verification seal (hologram or tamper-evident sticker) removed or damaged, are not eligible for warranty coverage. Damage caused by improper installation, electrical surges, or physical damage is not covered.
Returns
Returns are accepted within 30 days of delivery. Boards that are unopened and uninstalled, in original condition with the verification seal (hologram or tamper-evident sticker) intact, qualify for a full refund. If the board has been opened or installed, contact us before sending it back with a photo of the board you received, the reason for the return, and a photo of your original board's part-number label so we can verify fitment and approve the return. Boards returned used, altered, damaged, or with the verification seal missing may receive a partial refund in line with our return policy. Exchanges for the correct part are always available.
Not sure it's the board? Before you order, and before you return, contact us. We offer free troubleshooting help and can usually tell from a photo of your board and its symptoms whether this is the right part. Only a technician can fully diagnose your appliance.
