What Is the DA94-05311L Samsung Refrigerator Main Control Board Replacement?
The DA94-05311L is the main control board for Samsung refrigerators, a PCB assembly with EEPROM that mounts on the rear of the cabinet near the compressor compartment. As a replacement control board it manages compressor cycling, defrost timing, temperature sensor readings, and communication with the display and dispenser. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the DA94-05311L Fix on a Samsung Refrigerator?
This board is the likely fix when you're seeing any of the following:
- Refrigerator not cooling or freezer not freezing
- Display panel unresponsive, blank, or flashing
- Fridge runs constantly or won't shut off
- Ice maker or dispenser not working
- Temperature fluctuations between fridge and freezer compartments
- Refrigerator has no power or won't start
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 ordering, check the label on your existing board rather than relying on the refrigerator's model number alone. Unplug the unit, pull it away from the wall, and remove the rear access panel to find the board. If the sticker reads DA94-05311L, that's a match for this part. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- 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. Samsung 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.

Board Type and Function
This board acts as the refrigerator's central processor, reading input from temperature sensors and translating that data into commands for the compressor and defrost heater. It also handles communication between the control system and the front display or dispenser panel, so a fault here can show up as anything from erratic cooling to a dead display. Because nearly every cooling and user-facing function routes through this board, problems that seem unrelated - like a stuck display and a warm freezer - often trace back to the same part.
Common Samsung Refrigerator Error Codes
If your Samsung refrigerator is displaying an error code, the table below describes what it typically indicates. These are general Samsung codes and can vary by your exact model, so use this as a general guide. Codes marked ★ are most directly associated with main control board failure. Always confirm the exact meaning in your model's owner's manual or service guide before ordering any part.

Compressor abnormal current - board-managed compressor circuit fault |
| ★ 85E / 85C |
Low voltage error detected by main control board |
| 84C / 84E |
Compressor rotor locked - most severe Samsung error. Requires immediate professional service |
| 1E / SE |

How to Install a Samsung Refrigerator Main Control Board
Unplug the refrigerator before starting, and take basic static precautions when handling the board. Remove the rear access panel to expose the control board, then photograph the wiring harness connections before disconnecting anything so you know exactly how they go back. Disconnect each connector, noting orientation, then remove the old board and install the new one in its place. Reconnect the wiring using your photo as a guide, replace the access panel, and restore power. Most people finish this install in under 30 minutes with basic hand tools. Give the refrigerator a few hours to cycle and stabilize before judging whether the repair solved the problem.
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 our verification stickers or holograms removed or damaged, are not eligible for warranty coverage. Damage caused by improper installation, electrical surges, or physical damage is not covered.
Returns
Returns accepted within 30 days of purchase. Items must be returned in original condition. All returns may be subject to deductions for original and return shipping fees. Restocking and retesting fees may apply to opened or installed boards - these fees are waived for exchanges, though reshipping costs and any price difference between products will apply. Boards returned with physical damage, missing components, missing or damaged hologram stickers, or signs of improper installation may not be eligible for a full refund.
Important Installation Notes
This is not a universal control board - it is a direct replacement for the part number printed on your original board. Boards that look identical can be programmed differently, so always match the number on the sticker.
Some models may require a firmware update after installation; firmware updates and configuration changes should be performed by a qualified technician. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
Installation is performed at your own risk. By installing this part yourself you assume all risk of the repair, and Appliance Pro USA is not responsible for damage to your appliance or property, lost or spoiled food, or injury occurring during or after installation. If you are not comfortable working around electrical components, have a qualified technician install this part. If there is ever an issue with the part itself, your remedy is repair, replacement, or refund under our warranty and return policies.
Even if you end up calling a pro, knowing your part number and symptoms before the tech arrives usually shortens the visit and the bill.
