What Is the DA94-05316A Samsung Refrigerator Main Control Board Replacement?
The DA94-05316A is Samsung's main electronic control board for French-door and 4-door refrigerators, mounted in the rear machine compartment near the compressor and wired into the main harness. This replacement control board carries the onboard EEPROM and handles compressor cycling, defrost timing, and communication with the ice maker, dispenser, and control panel. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the DA94-05316A Fix on a Samsung Refrigerator?
This board is commonly the cause when you see any of the following:
- Refrigerator not cooling
- Freezer not freezing
- Refrigerator not defrosting
- Ice maker not working
- Water dispenser not working
- Control panel not working
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 sticker on your existing board against DA94-05316A - it's usually printed on a white or silver label attached to the board itself. Matching this number, not just your refrigerator's model number, is what confirms you have the correct part. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- 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 confirmed to fit the following Samsung refrigerator models:
RF29A9771SG, RF29A9771SR and additional Samsung models.
Also reported to fit: RF29A9771SR/AA, RF29A9771SG/AA. This is general reference material - confirm by the part number on your board's sticker before ordering.
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.

Key Features
- Genuine OEM Samsung main control board - not an aftermarket copy
- Includes the onboard EEPROM required for proper compressor cycling and defrost timing
- Manages communication with the ice maker, dispenser, and control panel
- Minor cosmetic wear may be present due to prior installation - it does not affect performance
Board Type and Function
A refrigerator's main control board is the unit that decides when the compressor runs, when the defrost heater fires, and how the fridge and freezer sections talk to each other electronically. On these Samsung models, the board also routes signals to the ice maker, water dispenser, and front control panel, so a failure here can knock out cooling and those accessory functions at the same time. Because the board stores calibration data on its EEPROM, a bad board often mimics a sensor or compressor fault even when those parts are fine.
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.
| Code |
What It Means |
| ★ 41E / 41C / PC ER |
Communication failure between main control board and display panel |
| ★ 88 88 |
Control board communication loss - not demo mode. Reset first; if it returns, board diagnosis needed |
| ★ 83E |
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 |
Freezer temperature sensor failure |
| 2E |
Fresh food compartment temperature sensor failure |
| 4E |
Freezer defrost sensor failure |
| 5E |
Defrost function error / defrost sensor failure |
| 8E |
Ice maker sensor failure |
| 21E |
Freezer evaporator fan not running |
| 22E |
Fresh food evaporator fan not running |
| 23E |
Condenser fan failure |
| OF OF |
Demo mode active - cooling fully disabled. Not an error code |

How to Install a Samsung Refrigerator Main Control Board
Unplug the refrigerator before doing anything else, then remove the rear or lower access panel to expose the board. Take a photo of the wiring harness before you disconnect anything, then label each connector as you remove it so reassembly is straightforward. Ground yourself with a wrist strap or by touching bare metal before handling the new board, since these boards are static-sensitive. Back out the mounting screws, lift out the old board, set the new one in place, and reconnect every connector fully before restoring power. Most techs finish this swap in under 30 minutes with basic hand tools. Give the refrigerator a few hours to complete a cooling and defrost cycle before deciding 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.
