What Is the EBR81182758 LG Refrigerator Main Control Board Replacement?
The EBR81182758 is a genuine OEM replacement control board for LG side-by-side and French door refrigerators, also sold under the Kenmore Elite brand on LG-built units. It's mounted inside a control box assembly, usually at the rear of the cabinet or in a housing near the compressor compartment, separate from the door-mounted display panel. This board manages compressor cycling, temperature regulation, and coordinates the evaporator and condenser fans to keep both sections at the right temperature. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the EBR81182758 Fix on a LG Refrigerator?
If your refrigerator is showing any of these problems, a failing control board is a likely cause:
- Freezer stays cold but the fridge section runs too warm
- Refrigerator won't cool or run at all
- Control panel doesn't respond when you press buttons
- Compressor won't start or kicks on and off at odd intervals
- Evaporator or condenser fan won't run, leading to weak airflow
- Display locks up or shows a control-related error code
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?
Open the rear access panel or control box housing and look for the board's printed number - EBR81182758 is the one you want to match, whether your unit is badged LG or Kenmore Elite. Since these are the same board sold under two names, don't worry if your model tag doesn't say LG - the number on the board sticker is what confirms the fit. Your LG refrigerator part number is on the sticker on the original board - look for the EBR or CSP prefix.

Reported fit is general reference material - confirm by the part number on your board's sticker before ordering.
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
- Manages compressor cycling, fan operation, and temperature regulation for both fridge and freezer sections
- Same board sold under LG and Kenmore Elite branding, so cross-brand fit is built in
- Minor cosmetic wear may be present due to prior installation - it does not affect performance
Board Type and Function
This is the main control board that runs the cooling system on these refrigerators. It tells the compressor when to cycle, keeps the fridge and freezer at their set temperatures, and manages the evaporator and condenser fans so cold air moves where it needs to go. When this board fails, the symptoms usually show up as uneven cooling, a fan that won't run, or a compressor that won't start at all, since every one of those functions runs through this one board.
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.

How to Install a LG Refrigerator Main Control Board
Unplug the refrigerator before you touch anything inside the control housing. Remove the rear access panel or control box cover to reach the board, and take a photo of the wiring harness before you disconnect anything - it makes reconnection straightforward. Handle the new board by its edges and avoid touching the components directly, since static discharge can damage it. Reuse the existing mounting hardware and connectors unless your install instructions say otherwise, then reverse the steps to put the panel back on. Most people finish this swap in under 30 minutes with basic hand tools, though units with a front dispenser panel can take a bit more disassembly to get at the board. Once it's back together, give the refrigerator a few hours to reach temperature before you decide 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.
