DA92-00483B Samsung Refrigerator Compressor Inverter Board: The Quiet, Code-Free Failure and Install Guide
Samsung French-door fridge running warm with a silent compressor and a display that looks completely normal? This inverter board is usually why, and it will not show a code to prove it. Which letter to match, the checks that confirm it, and the swap.
The DA92-00483B is the compressor inverter board on Samsung's AW2-14 inverter platform, the small board that cycles the compressor on and regulates its speed on H-generation French-door and 4-door refrigerators. When it fails, the classic sign is a warm cabinet with a completely silent compressor and a display panel that still looks normal, no error code points you at it. DA92-00483B is the number on your board's sticker, match the final letter exactly; a neighboring number ending in C is a different board from the same production generation, not this one. Send us a photo of your board sticker if you want it confirmed first.
Even if you end up calling a tech, these checks mean you can tell them exactly what you found, which usually shortens the visit and the bill.
DA92-00483B or DA92-00483C: Which Number Is on Your Sticker?
DA92-00483B is the number stamped on your inverter board's white sticker. DA92-00483C is a separate board from the same production generation, not a revision of this one. Match every character on the sticker before you order.
DA92-00483B is simply the number on the sticker, and it is also what shows up in parts catalogs under aliases like AP5914908 and PS9604079. The number that matters is whichever one is printed on your board, right down to the final letter. A board ending in C is a different part from the same family and production generation as this one. A board ending in N is a different part from the same family too, but it carries a later parts-block number and is a later-introduced variant of the same base, with no supersession tying any of the three together.
This is not a universal board. It is a direct match for the number on your original board's sticker. A board that looks the same from across the room can carry a different letter, so read the sticker rather than judge by eye.
| Number on the board | DA92-00483B, printed in full on the white sticker on the board itself |
| Cross references | AP5914908 and PS9604079 point to the same board in other catalogs |
| Board type | Compressor inverter board on Samsung's AW2-14 inverter platform, roughly 163 by 98 millimeters. It cycles the compressor on and off and regulates its speed. It is not a main control board and not a display or power board |
| Related number | DA92-00483C is a separate board from the same production generation as this one, not a revision. DA92-00483N is a separate board too, carrying a later parts-block number and a later-introduced variant of the same base. No published supersession ties any of the three together anywhere we could check |
| Family fit | H-generation Samsung French-door and 4-door refrigerators across the RF22, RF23, RF25, RF26J, RF28 and RF30 families |
| One limit worth knowing | We have not found a published error-code table tied to this board. As far as we have seen, its failures commonly show no code at all, so diagnosis here runs on listening and observation, not a code lookup |

Not listed? Run your model through the check above and use its buttons; a missing model is not the same as incompatible.
Our confirmed list below is a floor, not a ceiling. Catalogs differ on how they count revision suffixes, and coverage keeps growing as more units get checked against the sticker.
This model list is for reference only. Samsung can pair the same inverter board with different letters across a production run, so two refrigerators sharing a model number can still need a different suffix on this part. Always order by the number on your original board's sticker, it is the only identifier that decides. This board turns up across the RF22, RF23, RF25, RF26J, RF28 and RF30 prefixes, so any model starting with those is worth checking with the tool above.
Samsung Refrigerator Not Cooling With No Error Code: Is It the DA92-00483B Inverter Board?
A failing DA92-00483B commonly takes the compressor down without posting any error code, the display and lights keep working normally. A warm cabinet with a silent compressor and a normal panel is this board's signature. Five checks below help you confirm it before you order.
Unplug the refrigerator before you take any panel off. These are the complaints that bring people to this board.
- Samsung French-door or 4-door refrigerator running warm with the display and lights working normally
- Compressor completely silent, no hum, no click, no attempt to start
- No error code or fault light anywhere on the control panel
- Refrigerator was fine, then quietly stopped cooling with nothing on the display to explain it
Some Samsung refrigerators in this family do show fault codes for other systems, but we have not found a published code tied specifically to this inverter board failing. As far as we have seen, it fails quietly, so treat a warm cabinet with a silent compressor and a normal-looking panel as the signature, not a code you are missing.
Work through these before you order. They cost a few minutes and mean you order once, with confidence.
Read the white sticker on the board in place, before anything is opened. The final letter is what decides fitment here.
This is the check that matters most for this board. A failing inverter commonly takes cooling down without ever posting a code, the panel and lights stay completely normal.
A loose or partly melted connector can look exactly like a dead board from the front of the fridge.
A compressor fighting a packed condenser coil or blocked airflow runs hot and can trip its own protection, which looks like a dead inverter board from where you are standing.
If the sticker matches, the connectors look clean and airflow is clear, the last step is confirming power actually reaches the compressor.
Once the sticker, the wiring, the airflow and the compressor circuit all check out, replacing this small board is what keeps the compressor, the cabinet and the rest of the refrigerator in service, instead of a whole appliance going out over one board that cycles a compressor.
How Do You Replace a Samsung Refrigerator Compressor Inverter Board (DA92-00483B)?
The DA92-00483B swaps in once you have matched the sticker letter and ruled out wiring and airflow. Panel access varies across this model family, so most installs run under an hour with basic hand tools.
Unplug the refrigerator first. Find this board using your model's tech sheet or service manual, since panel access varies by model in this family. Photograph the board with every plug connected before you touch anything, touch the metal frame to discharge static, then unplug each connector by hand, pulling on the plug body rather than the wire. Remove whatever mounting hardware holds it in place and lift the board free. Set the new board in the same orientation, then put every plug back exactly where your photo shows it, refit the mounting hardware and panel, then restore power.
Why Is Your Samsung Fridge Still Not Cooling After the Inverter Board Swap?
A new DA92-00483B that does not fix a warm, silent fridge usually means a connector, the airflow, or the compressor circuit itself is still the problem. Recheck the wiring and the signature before you judge the board.
A different-looking board is a stop sign, not a shrug
A board that does not match what came out is not normal for this part. If yours arrived looking different, or a sticker element does not line up, stop before you install it.
Reseat every plug exactly where it was
A plug on the wrong header behaves exactly like a dead board, so check each plug against your photo.
Listen again for the signature
If the cabinet is still silent and warm with a normal-looking display, the new board has not actually fixed the symptom you started with.
Go back to wiring and airflow
A loose connector or a blocked coil missed the first time will make even a good board look like it failed.
Still stuck?
Give the refrigerator several hours at a normal setting before judging the swap. If the compressor is still silent after that, have a qualified technician check the compressor circuit next.
How Do You Help a New Inverter Board Last?
Voltage spikes, heat and moisture are the main threats to a Samsung refrigerator inverter board. Three quick checks while you have access protect your new DA92-00483B.
While you have things open, three quick checks help the new board live a long life.
- Put the refrigerator on surge protection. A power spike from a storm, a utility fault or a generator changeover runs straight through a small board like this one, and short repeated outages add up faster than one long one. A surge protector rated for a large appliance is cheap insurance.
- Keep airflow clear around the compressor. A compressor working against blocked airflow runs hotter and longer, and the board driving it runs hot right along with it. Clear any dust or lint you find around it and give it room to breathe.
- Check for moisture near the board. A weeping water line or a blocked drain can put moisture into places electronics do not belong. Wipe the area dry and look for staining before you close everything up.
Which Parts Are Worth Checking While the Fridge Is Open?
Worth a look while the inverter board is exposed: the EEPROM board catalogs show buyers pairing with it, the compressor wiring harness, and the condenser fan. The compressor mounting hardware is worth a glance too.

What Else Do People Ask About the DA92-00483B?
DA92-00483B commonly fails silently, with no error code, and it is easy to confuse with the separate DA92-00483C board from the same production generation. No programming step is documented for this board, and a replacement that does not match what came out is a stop sign, not a shrug.
Why does my Samsung refrigerator show no error code when this inverter board fails?
A failing DA92-00483B commonly takes the compressor down without lighting up any fault code, the display and panel keep working normally. We have not found a published error-code table tied to this specific failure, so the reliable signal is a warm cabinet paired with a silent compressor and an otherwise normal-looking panel.
Is DA92-00483B the same board as DA92-00483C?
No. They are separate boards from the same production generation, sharing a number block but not interchangeable as far as any record shows. No supersession ties one to the other anywhere we could check, so match the final letter on your sticker exactly.
Does the DA92-00483B control my refrigerator's fan speeds?
Its confirmed job is cycling the compressor on and off and regulating its speed on the AW2-14 inverter platform. No source we checked attributes fan control to it.
My replacement board looks different from the one I removed. Is that normal?
Not automatically, and it is worth checking before you install it. Compare the sticker and connector layout against a photo of the board you took out. If it does not line up, stop before you install it and get photos of both boards ready to compare.
Which Samsung refrigerators use the DA92-00483B?
It fits H-generation French-door and 4-door refrigerators across the RF22, RF23, RF25, RF26J, RF28 and RF30 families. Use the model checker above and match the sticker on your old board to be sure.
Does the DA92-00483B need programming after I install it?
We have not found any record of programming, pairing or a setup step for this board. As far as we have seen, it goes in as a straight swap. Give the refrigerator several hours at a normal setting before you judge the install.
My Samsung fridge is completely silent and warm, but the display looks fine. Is that enough to say it's the inverter board?
It is the classic sign for this board, but it is worth ruling out the cheaper causes first. Check the wiring plugs, clear any blocked airflow around the compressor, and confirm the sticker before you order. If those all check out and the compressor still will not run, this board is the usual answer.
