What Is the DA94-06788H Samsung Refrigerator Main Control Board Replacement?
The DA94-06788H is the main control board for this line of Samsung refrigerators, mounted behind the rear or top access panel of the cabinet. As the replacement control board, it manages compressor cycling, defrost timing, fan operation, temperature sensor readings, and communication with the ice maker and display. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
This board is also stamped or listed as DA9406788H (the same number without the dash), DA41-00867C, and ASM32184 - all of these refer to the same control board, so don't rule this part out if your old board shows one of those instead of DA94-06788H.
What Does the DA94-06788H Fix on a Samsung Refrigerator?
This board is the likely fix if your refrigerator is showing any of the following:
- Fridge or freezer section not cooling properly
- No power to the unit at all
- Display or control panel not responding to input
- Ice maker won't make ice
- Compressor or fans won't kick on
- Refrigerator is throwing error codes 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?
Match the number on your original board, not just the refrigerator's model number. Unplug the fridge, pull it away from the wall, and open the rear or top access panel to find the board and its printed sticker. DA94-06788H, DA9406788H, and DA41-00867C on that sticker all confirm this is your board. This board is also catalogued under ASM32184, DA41-00867C, DA9406788H, SJ-DA94-06788H - any of those numbers on your sticker means this is your board. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- 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. 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
The main control board is the brain of the refrigerator. It reads input from the temperature sensors and decides when to run the compressor and fans to keep both compartments at the right temperature. It also manages the defrost cycle timing, controls the ice maker, and handles communication between the refrigerator and the display or user interface panel. When this board fails, the whole system can lose the ability to cool, defrost, or respond to the control panel.
Common Samsung Refrigerator Error Codes
If your Samsung refrigerator is displaying an error code, the table below describes what it typically indicates.

How to Install a Samsung Refrigerator Main Control Board
Start by unplugging the refrigerator and giving yourself room to work at the back of the unit. Remove the rear or top access panel to expose the control board, and take a photo of the wiring harness connections before you pull anything apart. Use basic anti-static precautions when handling the new board - touch a grounded metal surface first. Disconnect the old board, swap in the new one, and reconnect the harnesses using your photo as a guide. Most people finish this swap in under 30 minutes with basic hand tools. Once it's back together, give the refrigerator a few hours to stabilize temperature 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 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.
