DA92-00483N Samsung Inverter Board: Is There a Service Number to Match?
Samsung prints the production number across the board's white label. Copy every character, including the letter at the end, before you order.
A later production run can ship with a slightly different sticker layout or a small design change. Size, connector layout and mounting points should still match the board you removed. If anything looks off, stop 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 inverter 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 Refrigerators Take the DA92-00483N Inverter Board?
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 inverter board mounts at the rear of the refrigerator, inside a protective cover on the compressor compartment near the bottom rear of the unit, next to the compressor and the main control board. 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 DA92-00483N and check it character by character.
Samsung Refrigerator Not Cooling or Clicking: Is the DA92-00483N Inverter Board at Fault?
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.
Some Samsung models flash an error code for this circuit: 81E, 82E, 83E, 84E and 44E all point at the compressor or its communication with this board. A 23E code points at the condenser fan circuit instead, not this board.
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 number on your sticker
Read the full production number on your old board before anything else. If it matches DA92-00483N character for character, this is your board.
Read the error code, if there is one
An 81E, 82E, 83E or 84E code points at the compressor circuit this board drives. A 44E code points at communication between the main control board and this inverter board. A 23E code points at the condenser fan instead.
Check the temperature sensor
A shorted or open temperature sensor feeds the board bad information, and that is not the board's fault. Compare its reading against the wiring and test chart packed inside the appliance before you replace anything.
Listen to the compressor itself
A compressor that hums, clicks and shuts off on its own can still have a healthy board behind it. If the compressor is seized or badly worn, a new board will not fix it.
Check the condenser fan
A 23E code or a warm unit with the compressor running can point at a stuck condenser fan instead of this board. Spin the blade by hand and confirm it is not dragging.
Once the sticker, the error code, the temperature sensor and the compressor and fan check out, the board is what is left. You need a replacement inverter board, and you order it once. A failing compressor or a shorted sensor can stress the board driving them, so a board that just failed may not be the only reason the fridge went warm. Keep a spare on the shelf and a dead compressor circuit becomes a short repair instead of days of spoiled food.
How Do You Replace the DA92-00483N Samsung Refrigerator Inverter 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.
Disconnect power at the wall. Move or discard perishable food before you start, since the fridge will warm up during the swap.
Take out the screws holding the cover over the compressor compartment and set them aside.
Shoot the board with all wiring still attached. This photo is your map for reconnecting everything later.
Touch bare metal on the frame first. Unplug the wiring harness connectors and the compressor leads, noting any locking tabs.
Lift the old board free by its edges. Set the new board in place and reconnect each plug from your photo.
Seat the cover and replace its screws. Confirm every connector is seated before you close the fridge back up.
- ✓I read the full sticker on my old board and matched DA92-00483N
- ✓I photographed the wiring before I disconnected anything
- ✓I checked the temperature sensor against the tech sheet
- ✓I confirmed the compressor and condenser fan both check out
- ✓I have the new board's bag sealed until I am ready to install
This board goes in as a straight swap on the models it fits. We have no setup or programming step on record for a standard replacement. Give the refrigerator several hours at a normal setting before you judge the cooling. 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.
Why Is the Refrigerator Still Warm After You Replace the DA92-00483N?
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 photo
Size, connector layout and mounting points should match the board you removed. Send us both photos if anything looks different.
Reseat every connector
A plug pushed on at an angle looks seated but is not. Press straight in until it clicks.
Recheck the temperature sensor
A sensor that was marginal before the swap gives the new board the same bad reading it gave the old one.
Listen for the compressor
If the compressor still hums and shuts off with a new board installed, the compressor itself may be the fault, not the board.
Give it time, then check the code
Allow several hours before judging the result. If an error code returns, write it down and compare it to the codes above.
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 a New DA92-00483N Inverter Board Last?
Add surge protection
A spike from the utility or a storm travels straight into the board driving the compressor. Protecting the outlet is cheap insurance.
Clean the condenser coil and fan
A dusty coil and a struggling fan make the compressor and the board behind it run hotter and longer than they should.
Watch the compressor you just connected
A compressor that was already weak before the swap can wear down a healthy board the same way it wore down the old one.
What Else Is Worth Checking While the DA92-00483N Is Out?
Temperature sensor Do it now
Sits near the evaporator and feeds the board its reading. Cheap, and worth changing if its reading was out of range on the tech sheet.
Condenser fan On noise
Already exposed with the rear cover off. A dragging blade works the compressor and the board harder.
Main control board On 44E
Shares wiring with this inverter board, and a 44E code points at communication between the two.
Compressor If locked
If it is seized or locked (84E), a new inverter board alone will not restore cooling.

What Else Do People Ask About the DA92-00483N?
Why does searching DA92-00483N turn up so little?
Samsung has not issued a separate service number for this part on record, so distributors list it under cross-reference numbers like AP6031087 or PS11766595 instead. Search those if DA92-00483N alone comes up short. The production number on your sticker is still the one to match.
What ships in the box with the DA92-00483N?
The DA92-00483N inverter board ships ready to install. Keep it in its packaging until you are ready to swap it in.
My replacement board looks different from the one I took out. Is it wrong?
Stop before you install it. Compare size, connector layout and mounting points against 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 and retesting fee.
Does the DA92-00483N need programming or setup after I install it?
No setup step is on record for a standard replacement. It goes in as a straight swap. Give the refrigerator several hours 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.
Does this board work with a conventional, non-inverter compressor?
No. The DA92-00483N is built to drive a variable-speed inverter compressor, not a conventional single-speed one. Check your model against the fitment list before you order.
What do the 81E, 82E, 83E, 84E and 44E codes mean?
81E means the compressor failed to start, 83E means it drew abnormal current, and 84E means it is locked. 82E points at the inverter board itself, and 44E points at communication between the inverter board and the main control board.
