DA94-06788A: Is the Sticker Number the Only One You Need?
Match every character on the white label on your Samsung board, including any trailing letter. The numbers stamped into the green board are component references, and they are not what you order by.
A later production run can carry a slightly different label or print layout. Size, connector layout and mounting points should still match the board you removed. If they do not match, pause the install and send us both photos: the board that came out with all of its stickers, and the one that arrived.
This is not a universal main 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.
Which Samsung RF29 Refrigerators Use the DA94-06788A?
Not listed? A missing model is not the same as incompatible. Go by the sticker on your old board, or use the check above and send us a photo.
The board sits inside a control board cover, either at the back of the unit or behind an interior access panel, depending on the model. This model list is for reference only. Samsung may change boards between production runs, so two refrigerators 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.
Opened or installed boards may carry a restocking and retesting fee, so compare the sticker before you open the anti-static bag. Hold yours next to DA94-06788A and check it character by character.
Samsung Fridge Not Cooling: Is It the DA94-06788A or Something Else?
These checks help you rule out the common causes before you order. Only a qualified technician on site can confirm the fault in your refrigerator. Unplug the refrigerator before you take any panel off, and stop at any step you are not comfortable with.
This board does not show a code of its own, so work through the symptoms below instead.
Let's verify it is the board by checking the common parts that contribute to these failures. They are inexpensive, easy to check, and ruling them out means you order once, with confidence.
Confirm the sticker number
Read the sticker before anything comes apart. If it reads DA94-06788A, you have the right part in hand.
Check the outlet and the breaker
Plug a lamp into the same outlet to confirm power is reaching the unit. A tripped breaker or dead outlet looks just like a dead board.
Test the temperature sensors
A shorted or open sensor hands the board a bad reading, and that is not the board's fault. Compare each sensor against the wiring and test chart packed inside the appliance before you order a board.
Check the defrost heater and thermal fuse
Both should pass a continuity check. Heavy frost on the back wall with a good board usually means one of these opened, not the control board.
Listen to the compressor and both fans
A struggling compressor or a stalled fan drags on the board driving it. Spin each fan by hand and listen for a compressor that hums without starting.
Once the power, the sticker, the sensors, the defrost parts and the compressor all check out, the board is what is left. You need a replacement main control board, and this time you order it once. A fan or sensor that failed first often drags on the board for weeks before it gives out too. Keep a spare on the shelf and a warm refrigerator becomes a short repair instead of a week of spoiled food.
How Do You Replace the DA94-06788A Samsung Refrigerator Control Board?
Repair times and difficulty levels are general estimates and may vary by model, tool availability, and experience. This is provided as general guidance only and is not a substitute for professional service. Food is normally fine during a typical install, but we highly recommend moving it to a cooler with ice as a precaution - Appliance Pro USA is not responsible for lost or spoiled food.
Unplug the refrigerator at the wall. Find the control board cover at the back of the unit or behind the interior access panel.
Before you unplug anything, photograph the board with all its wiring in place. This is your map for reassembly.
Take off the control board housing cover, then disconnect the wiring harness connectors one at a time. Never pull on the wire itself.
Handle it by the edges. Keep it until the new board is confirmed working.
Set the new DA94-06788A in place and reconnect every plug using your photo as a guide. Each connector fits only one way.
Refit the control board cover and secure it. Plug the refrigerator back in before you judge the result.
- ✓I read my sticker and it matches DA94-06788A character for character
- ✓I checked the outlet and the breaker before blaming the board
- ✓My temperature sensors read within range on the tech sheet
- ✓The defrost heater and thermal fuse both passed a continuity check
- ✓I photographed every connector before I unplugged anything
On this board, fitting it is a straight swap. We have not come across a programming step on a standard replacement. Give the refrigerator a few hours at a normal setting before you judge the result. The 5-mil nitrile gloves in the box give grip and some protection, but they are not cut-proof. Hold the board by its edges and mind the sheet-metal edges of the cover.
Fridge Still Warm After You Install the DA94-06788A?
Clicks and relay sounds are normal. The compressor may stay off for several minutes as a protection delay.
Fans run, compressor hums, and cold air shows up in the freezer first.
Both sections reach near set temperature. Do not load warm groceries before this.
Temperatures stabilize and the ice maker resumes. Now decide whether anything is wrong.
Once power is back on, the board compartment is live. Do not reach into it or reseat a plug with the refrigerator plugged in. Unplug first, every time.
Check the new board against your old one
Size, connector layout and mounting points should match the board you removed. If they do not, pause and send us both photos.
Reseat every connector
A plug pushed in at an angle reads as a dead board. Go through your photo and confirm each one is fully seated.
Go back to the temperature sensors
A sensor stuck open or shorted hands the new board the same bad reading it gave the old one. Check the tech sheet again.
Confirm the sticker matches what you ordered
Compare DA94-06788A against the sticker on the board now installed. A mismatch points to a packing error, not a bad board.
Still stuck? Talk to us before you return anything
Give the refrigerator a few hours at a normal setting, then reach out with the symptom and your photos.
The troubleshooting steps above are general guidance only and may not apply to every model or situation. If you are unable to resolve the issue after following these steps, we recommend contacting our team or consulting a qualified appliance technician before taking further action.
How Do You Help the DA94-06788A Last?
Surge protection
A power spike from a storm or a generator changeover can travel straight to the board. Several short outages back to back stress it more than one longer outage.
Clean the condenser coil
A dusty coil makes the compressor and fans run longer and hotter, and the board runs hot along with them.
Check door seals and the drain
A blocked defrost drain or a weeping water line puts moisture into the board housing. Wipe the area dry and look for staining.
What Else Is Worth Checking While the DA94-06788A Is Exposed?
Temperature sensors Do it now
Inexpensive and already exposed. A worn sensor can make a good board look faulty, so replace it if it is original.
Defrost heater and thermal fuse On frost
Already accessible with the same panel off. Getting back here later means emptying the freezer again.
Evaporator and condenser fan motors If it rumbles
A fan with a worn bearing runs hot and works the board harder. Replace it if it rumbles or drags.
Door gaskets If torn
A loose or torn gasket lets warm air in, and the board runs the compressor longer trying to compensate.

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. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.

Minor cosmetic wear may be present due to prior installation - it does not affect performance.
What Else Do People Ask About the DA94-06788A?
Why does searching DA94-06788A bring up so few results?
Samsung does not list a separate service number for this part, so the production number on the sticker, DA94-06788A, is the only number to search. Some boards also show DA41-00867C stamped nearby, a production number also seen on related Samsung boards, but DA94-06788A on your sticker is what confirms the fit.
What ships in the box with the DA94-06788A?
The box includes the DA94-06788A control board ready to install. Check your packing slip for any additional included materials.
My replacement board looks different from the one I took out. Is it wrong?
Stop and compare before you install it. Size, connector layout and mounting points should match the board you removed. Send us a photo of the board you removed with all of its stickers and a photo of the one that arrived, and we will confirm before you go further.
I ordered the wrong board. What now?
Leave the bag sealed and contact us first. An exchange is the fastest path. Opened or installed boards may carry a restocking fee.
Does the DA94-06788A need programming or setup after I install it?
On this board, fitting it is a straight swap with no programming step we have come across. Give the refrigerator a few hours at a normal setting before you judge the result. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
My Samsung refrigerator shows no error code. How do I know it is the board?
Many of the refrigerators this board fits do not display a code at all. Work through the symptoms and checks above instead of waiting on a code that will not appear.
My refrigerator is completely dead. Is it the board?
Check the outlet, the cord and the breaker first. If power is confirmed and nothing inside responds, the DA94-06788A is a strong candidate.
