What Is the DA94-06788A Samsung Refrigerator Main Control Board Replacement?
The DA94-06788A is the main control board for Samsung French-door and bottom-mount refrigerators. It's housed inside the control board cover at the back of the unit or behind an interior access panel, and it governs the systems that keep the cabinet cold - temperature regulation, cooling cycles, and defrost timing. If your original board has failed, this replacement control board restores normal operation. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the DA94-06788A Fix on a Samsung Refrigerator?
If your refrigerator is showing any of the following, this board is a common cause:
- Refrigerator not cooling
- Control panel or display unresponsive or frozen
- Error codes showing on the display
- Compressor or fans not kicking on
- Temperature readings jumping around or inconsistent
- No power at all - refrigerator completely dead
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 you order, pull the control board cover and check the sticker on the board itself, not just the model tag on the fridge. If you see DA94-06788A printed on that sticker, you've got the right board for your unit. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- prefix. On the board's sticker this number is printed without the dash, as DA9406788A, sometimes with a two-character lot code in front of it - it is the same part number.

Board Type and Function
This is the main control board for the refrigerator, meaning it's the brain behind day-to-day operation. It monitors internal temperature and cycles the compressor and fans to keep the fresh food and freezer sections at the right temperature. It also manages defrost timing so frost doesn't build up on the evaporator coil. When this board fails, you lose coordinated control over cooling, and that shows up as inconsistent temperatures, a dead unit, or a frozen control panel.

How to Install a Samsung Refrigerator Main Control Board
Most people finish this install in under 30 minutes with basic hand tools. Unplug the refrigerator first, then locate and remove the control board housing cover, either at the back of the unit or behind an interior panel. Take a photo of the wiring harness connections before you start pulling anything apart - it makes reconnection straightforward. Disconnect each connector from the old board, swap in the new DA94-06788A, and reconnect everything securely before closing the cover back up. Handle the bare board by the edges and avoid touching the components, standard static precautions apply. Once it's buttoned up and plugged back in, give the refrigerator a few hours to stabilize before you judge whether the repair worked.
