DA92-00763B Samsung Inverter Board: Is There a Service Number to Match?
The white Samsung sticker carries the full production number. Match every character, including letters at the end, before you order.
DA92-00763B is reported as no longer made by Samsung, so stock can include a later printing of the label. Size, connector layout and mounting points should still match the board you removed. If they do not, 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 DA92-00763B 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 sits in the machine compartment at the rear-bottom of the refrigerator, near the compressor, usually behind a removable rear access cover close to where the compressor power leads enter. 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 DA92-00763B and check it character by character.
DA92-00763B Inverter Board: Do These Symptoms Point to It?
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.
If your display shows 44E, 81E or 82E, the panel is pointing at the inverter board or its wiring to the compressor. Confirm the code against your tech sheet before you order.
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 sticker on your old board in place, before anything is unplugged. If it reads DA92-00763B, you are looking at the right part.
Check for a display error code
A 44E or 82E points at the inverter board or its connection to the main control. An 81E points at the wire harness between the board and compressor.
Test the temperature sensors
When a sensor reads wrong, the board acts on bad information, and that is not the board's fault. Compare each sensor against the tech sheet (the wiring and test chart packed inside the appliance).
Check voltage at the 7-pin connector
With power on, check for 13VDC across pins 1 and 2, and 5VDC across pins 3 and 4. Missing voltage points to the board, voltage present with a dead compressor points to the compressor.
Look at the wiring and connectors
Loose or corroded connectors at the compressor or board can mimic a dead board. Reseat every plug before you condemn the board.
Once the sticker, the error code, the sensors and the connector voltages check out, the board is what is left. You need a replacement inverter board, and you order it once. A compressor or wiring fault left in place can stress a new board the same way it stressed the old one. Keep a spare on the shelf so a warm fridge becomes a short repair instead of a week of coolers.
How Do You Replace the DA92-00763B Samsung 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 and wait a few minutes for the compressor to settle.
Remove the rear access cover and photograph the board with all wiring still attached.
Discharge static on an unpainted metal surface, then release each connector by hand.
Take out the screws holding the board in place and lift it free.
Set the replacement board in place and reconnect each wire exactly as you photographed it.
Replace the mounting screws, then refit the rear access cover.
- ✓I confirmed the sticker reads DA92-00763B before ordering.
- ✓I photographed the wiring before disconnecting anything.
- ✓I checked the 7-pin connector voltages and the board was the problem.
- ✓I touched a metal surface to discharge static before handling the board.
- ✓I matched every connector position from my photo before powering on.
On this board it goes in as a straight swap, with no programming step reported. 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.
Samsung Refrigerator Still Not Cooling After the DA92-00763B 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.
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 reads the same as a dead board. Press each one fully home.
Recheck the temperature sensors
A sensor that was marginal before can still feed bad information to a new board.
Recheck the 7-pin voltages
Confirm 13VDC and 5VDC are present at the connector with power on. If not, look at the board's power input before anything else.
Review every result before you return it
If every check passes and cooling still fails, document the symptom and keep your photos ready. Give the refrigerator several hours at a normal setting first.
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 DA92-00763B Inverter Board Last Longer?
Surge protection
A power outage or utility spike can hit the inverter board directly through the compressor leads. A simple surge protector lowers that risk.
Clean the condenser coil
A dusty coil makes the compressor work harder and run hotter, and the board runs hot right along with it.
Keep the compartment dry
Moisture around the rear access area can corrode connectors over time. Wipe up any condensation you find when the cover is off.
What Else Is Worth Checking While the Back Panel Is Off?
Compressor start components Check once
If the start device or overload is original and tired, it can wear on a new board the same way it wore on the old one.
Wiring harness to the compressor Hands on
Heat near the compressor can dry out insulation over the years. Inspect it for cracking while you have access.
Rear access cover seal If loose
A gap here lets warm air and dust into the compartment. Reseat or replace it if it is loose.
Defrost components If frosted
Separate from the inverter board but behind nearby panels. Check them if you see frost buildup.

What Else Do People Ask About the DA92-00763B?
Why does searching DA92-00763B turn up so little?
Samsung does not assign a separate service number to this part, so the production number is the only one to search. Some sellers list it as discontinued by the manufacturer while others still carry stock, so check your sticker number directly.
What ships in the box with the DA92-00763B?
The board sealed in an anti-static bag, the Quick Start Guide, a pair of 5-mil nitrile install gloves, and the warranty registration card.
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 fee.
Does the DA92-00763B need programming or setup?
No. It installs as a straight swap, with no programming or setup step reported after installation. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
How do I know it is the board and not the compressor?
Check the 7-pin connector on the board for 13VDC and 5VDC as described in the diagnose section. If those voltages are present and the compressor still does not run, the compressor itself is likely at fault.
Does this board fit every Samsung refrigerator?
No. It fits a specific set of RF, RH and RS model families, with 52 confirmed and 82 reported models on record. Check the sticker on your own board before you order.
