DA92-00486A: What Does This Samsung Refrigerator Board Number Mean?

Samsung prints the production number on the module's own label, not on a separate tag. Compare it character by character, since catalogs list this part under several different names.
Samsung has discontinued this part, so a replacement board can carry a different print date or minor label wording than the one you removed. Size, connector layout and mounting points should still match. If anything looks off before you install, 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 Use the DA92-00486A 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.
This board sits inside a sealed plastic housing in the machine compartment at the back of the refrigerator, near the compressor and condenser fan, behind a rear access panel. 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 DA92-00486A and check it character by character.
Samsung Refrigerator Not Cooling? Is It the DA92-00486A 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 has no error code of its own to read on the display. Diagnose it by which symptom matches above.
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 production number straight off the board's label before you open anything else. If it reads DA92-00486A and your model is on the fitment list, this is your part.
Find the separate inverter board
This module powers and switches components like the compressor and fans, while a separate inverter board controls compressor speed. Look near the compressor for that second board. A fault isolated to that part does not point back to this one.
Check the temperature sensors
A sensor that reads short or open feeds the board bad information, 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.
Spin both fans by hand
The condenser fan and the evaporator fan should turn freely with no drag or grinding. A fan that struggles pulls hard on the board driving it.
Confirm power at the board
With the unit plugged in, check that incoming voltage reaches the board's connector. Power present with no output from the board points to the module itself.
Once the sticker, the separate inverter board, the sensors and both fans check out, the board is what is left. You need a replacement inverter board, and you order it once. A fan that drags or a sensor that drifted can overwork the board driving it, so it may have failed for a reason beyond itself. Keep a spare on the shelf and a warm refrigerator becomes a fast swap instead of a long wait.
How Do You Replace the DA92-00486A Samsung Refrigerator 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.
Pull the plug at the wall before you touch anything. Give it a few minutes before you open the compartment.
Take out the screws holding the panel and set them aside. This gives you a clear view of the board in its housing.
Shoot a clear photo of every connector while it is still plugged in. This photo is your map for reconnecting the new board.
Touch the metal frame first to drain static. Unplug each connector by its own body, then unclip the board from its mounting points.
Seat the new board in the same mounting points. Reconnect each plug to the position it came from.
Refit the rear access panel and its screws. Plug the refrigerator back in and give it time to reach temperature.
- ✓I photographed my board's sticker and read every character
- ✓I confirmed the separate inverter board is not the actual fault
- ✓Both fans spin freely with no drag
- ✓The temperature sensors checked out against the tech sheet
- ✓I photographed the wiring before unplugging anything
On this board it goes in as a straight swap, with no programming step we have on record. Give the refrigerator several 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.
Why Is Your Samsung Refrigerator Still Not Cooling After the DA92-00486A Swap?
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.
Compare the new board to your photo
Size, connector layout and mounting points should match the board you removed. If they do not, send us a photo of each board before you go further.
Reseat every connector
A plug pushed in at an angle behaves like a dead board. Go through your photo one connector at a time.
Recheck the temperature sensors
A sensor stuck short or open feeds the new board the same bad reading it gave the old one.
Check the separate inverter board again
If that board is also tired, a good power module still will not bring the compressor up to speed.
Give it time before judging
Let the refrigerator run several hours at a normal setting. A board that was just installed needs that time to prove itself.
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 Your New DA92-00486A Board Last?
Protect against power surges
A surge from the utility or a generator changeover passes straight through this board. Repeated short outages wear on it more than one long one.
Keep the condenser coil clean
Dust on the coil makes the compressor and both fans run longer and hotter. The board runs hot right along with them.
Watch for moisture near the housing
A clogged drain or a weeping water line can put moisture into the board's sealed housing. Wipe the area dry and check for staining.
What Else Is Worth Checking Near the DA92-00486A?
Separate inverter board Near compressor
Mounted near the compressor, this board controls compressor speed and can fail on its own. If the compressor never ramps up, check it too.
Temperature sensors Do it now
Inexpensive and easy to reach once the panel is off. A bad sensor can make a good board look faulty.
Condenser and evaporator fans If noisy
A fan with a worn bearing runs hot and drags on the board driving it. Replace one that rumbles or drags.
Rear access panel seals If worn
Worn seals let warm air into the compartment and make every part inside work harder.

Opened or installed boards may carry a restocking and retesting fee, so compare the sticker before you open the anti-static bag. Minor cosmetic wear may be present due to prior installation - it does not affect performance.

What Else Do People Ask About the DA92-00486A?
Why does searching DA92-00486A bring up different part names?
Samsung and various parts catalogs list this part as a Module Assembly, a Power Control Board and a Control Board, not only as an inverter board. There is no separate service number on record, so the sticker's production number is what you search and order by.
What ships in the box with the DA92-00486A?
Appliance Pro USA ships the DA92-00486A in protective packaging with basic installation guidance. Check your packing slip if you believe something is missing.
My replacement board looks different from the one I took out. Is it wrong?
Stop and compare before installing. Size, connector layout and mounting points should match the board you removed. If they do not, send us a photo of the board you removed with all of its stickers and a photo of the one that arrived.
I ordered the wrong board. What now?
Leave the bag sealed and contact us first. An exchange is the fastest path, and opened or installed boards may carry a restocking fee.
Does the DA92-00486A need programming or setup after I install it?
On this board it goes in as a straight swap, with no setup step we have on record. Give the refrigerator several 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.
Is this the same as the inverter board that controls compressor speed?
No. This module powers and switches the compressor and fans, while a separate Samsung inverter board controls compressor speed and works alongside it. If the compressor runs but never changes speed, check that separate board.
My Samsung refrigerator has no error code. How do I know it is this board?
Many of the refrigerators this part fits give no code for this fault, so you diagnose it by symptom instead. If the sensors, fans and the separate inverter board all check out, this module is what is left.
