DA41-00404D Samsung Refrigerator Compressor Inverter Board: Changed to DA41-00614F, Same Chain as DA92-00047A
Samsung refrigerator compressor won't start, or the unit runs and still barely cools? This AW2-PJ inverter board is a common cause once the cheaper parts check out. DA41-00404D was later changed to DA41-00614F, and DA92-00047A sits on that same chain, so whichever number turned up in your search, the label on your own board is what decides which one you order.
The DA41-00404D is a compressor inverter board on Samsung refrigerators, internally labeled ASSY PCB INVERTER on the AW2-PJ platform. It regulates power to the compressor and controls its speed, which is what sets how much the unit cools. It is not a main control board; our record does not tie it to the display, defrost cycle, dampers or dispenser. If your Samsung refrigerator's panel is alive but the compressor never tries to start, or the unit runs and still will not cool down, this board is a common cause once the cheaper parts check out. Samsung later changed this number to DA41-00614F, and the related number DA92-00047A shares that lineage. DA41-00404D is the number on your board's own white sticker; if it reads DA41-00614F or DA92-00047A instead, order that number. 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.
DA41-00404D, DA41-00614F, DA92-00047A: Which Number Do You Order By?
DA41-00404D is the number printed on this board's own white sticker; order it against a board labeled DA41-00404D. Samsung's parts system later revised this number to DA41-00614F, and DA92-00047A is a documented chain neighbor, so search results or diagrams naming either of those are looking at this board's lineage, not a substitute for it. If your label reads DA41-00614F or DA92-00047A, order that number instead.
Samsung prints one number on this board, the white sticker, and no separate service number is documented for this part in the record we checked. What matters here is the chain behind that number. Samsung's parts system later revised DA41-00404D into DA41-00614F, and DA92-00047A rides the same chain, so a sticker, a parts diagram or a search result naming any of the three is looking at this board's lineage, not necessarily this exact part. This listing sells the board labeled DA41-00404D. If that is what your sticker reads, this is your board. If it reads DA41-00614F or DA92-00047A instead, that is the part to order.
This is not a universal board. It replaces the exact number on your original board and nothing else. A board that looks similar on the outside can still be wired for a different platform, so the sticker is what settles it, not the shape of the board.

Which Samsung Refrigerators Use the DA41-00404D, and Why Isn't There a Model List?
No published fitment list is attached to DA41-00404D anywhere we could check. With no list to point to, the number on your board's own label decides fitment, not a model number. If your label reads DA41-00404D, this is your board; if it reads DA41-00614F or DA92-00047A, order that number instead.
The white sticker carries the production number in full. Photograph it before the board comes out and order against what it says.
This inverter sits in the same place, the back of the refrigerator, on whichever model originally carried a matching label.
No catalog we checked publishes a model list tied to this exact number. Listing series or model numbers here would present someone else's fitment as this part's own, so we do not. The number on your original board's label is the only thing that decides fitment. If it reads DA41-00404D, this is your board. If it reads DA41-00614F or DA92-00047A, those are documented chain neighbors and order under that number instead. If you are not sure which you are holding, a photo of the label is enough for our team to check before you order.
Samsung Refrigerator Compressor Won't Start or Won't Cool: Is the DA41-00404D the Cause?
The DA41-00404D inverter regulates power to the compressor, so a Samsung refrigerator with a live panel, a compressor that never starts, and little or no cooling points at this board once the cheaper parts check out. Confirm house power reaches the board at CN75 and rule out visible board damage before you order.
Unplug the refrigerator before you take any panel off. These are the complaints that bring people to the DA41-00404D chain.
- Samsung refrigerator not cooling, or barely keeping up
- Compressor never tries to start, even though the panel lights up and responds normally
- Fans turn and the unit runs, but the compressor stays silent, sometimes with a single click before it goes quiet
- The refrigerator side stays warm while everything on the panel looks normal
- Visible burn marks or scorching on the board itself
A panel that is alive, lit and responding, paired with a compressor that never tries to start, is the pattern this board causes. A dead panel points elsewhere and is outside what this board explains.
No blink-code meaning is documented for this board, so diagnose it by symptom rather than by counting flashes on the board.
We rule out what mimics a dead inverter first. None of them cost much to rule out, and clearing them first means you only have to order once.
DA41-00404D, DA41-00614F and DA92-00047A sit on the same service chain, and the white sticker on your board is what tells them apart. Read it in place, before any packaging is opened.
A scorched spot or a burn mark on the board itself is a fast, free way to confirm a failed inverter before you test anything else.
This board causes a specific pattern, a working panel paired with a compressor that will not start. A dead panel is a different problem and points elsewhere.
Connector CN75, the red and grey wires, is where 120VAC line power enters this board. It is the feed the board needs before it can drive anything downstream, not the compressor output.
A loose or corroded connector clip can mimic a dead inverter, so check the connections first, then listen at the compressor. Repeated attempts that fade out are worth reporting to a technician along with what you found here.
A refrigerator that has stopped cooling is not, by itself, a reason to replace the whole appliance. The compressor, cabinet and sealed system typically have plenty of service life left, and this board is a self-contained repair behind a single panel, not a failure that touches the whole appliance.
How Do You Replace a Samsung Refrigerator Inverter Board (DA41-00404D)?
The DA41-00404D sits at the back of the refrigerator, near the compressor it drives. No install procedure is published for this board anywhere we could check. No programming, pairing or setup step is documented either, so plan on an unplug, swap and reconnect.
Unplug the refrigerator and pull it out far enough to reach the back panel covering the board. Take the panel off, photograph the board with every connector attached, then touch the metal frame to discharge static. Release each connector by its clip rather than pulling the wires, free the board from its mounts and lift it clear. Fit the new board the same way round, reconnect every connector from your photo, and refit the panel. No programming step is documented for this board.
Still Won't Start After You Swap the DA41-00404D?
A new DA41-00404D that changes nothing usually means a connector was not fully reseated or the real fault sits elsewhere. A board that does not match what came out is worth stopping over before you install it.
Check the new board against your photo
A replacement that does not line up with what you pulled, a different label, a different connector arrangement, a different mounting point, is not something to shrug off.
Reseat every connector
A connector clip that looks attached but is not fully seated behaves exactly like a dead inverter.
Recheck CN75 and the wiring
If the panel is alive and the compressor still will not start, have a qualified technician recheck house power at CN75, then check the connectors near the board before you rule the new board out.
Give it time
A compressor that has sat idle can take a few hours at a normal setting to catch back up, even with a good inverter driving it.
Still stuck?
If you have worked through the checks above and the compressor still will not run, this is past what more waiting will fix. Treat it as a stalled repair rather than a timing issue.
How Do You Make a New DA41-00404D Inverter Last?
Heat, moisture and power surges account for most of what shortens a Samsung refrigerator inverter board's life. Three quick checks while the back panel is off protect your new DA41-00404D.
While you already have the panel open, three quick checks help your new inverter hold up over time.
- Put the refrigerator on surge protection. This is the generation Samsung later revised, and a superseded number is a harder one to source twice. Surge protection is cheap insurance.
- Clean the condenser coil. A coil packed with dust makes the compressor and fans run longer and hotter, and heat is hard on any inverter. Pull the lower grille, vacuum the coil and shroud, and check the condenser fan spins freely.
- Check for moisture near the compartment. A blocked drain or a weeping water line puts moisture into the space where this board sits. Dry it off and look for staining before you button the panel back up.
What Else Is Worth Checking While the Panel Is Already Off?
A few Samsung refrigerator parts sit near the DA41-00404D at the back of the unit. Checking a worn one now means you are not back in this panel a second time.

What Other Questions Come Up About the DA41-00404D?
Most questions about the DA41-00404D center on whether to order it, DA41-00614F or DA92-00047A, whether DA41-00404E is the same board, and what a live panel paired with a dead compressor means.
What does the DA41-00404D inverter board actually do?
It is a compressor inverter board, internally labeled ASSY PCB INVERTER on the AW2-PJ platform. It regulates power to the compressor and controls its speed, which is what sets how much the unit cools. It is not a main control board, and our record does not tie it to the display, defrost cycle or dampers.
My board says DA41-00404D but the part I keep finding is DA41-00614F. Which do I order?
They sit on the same service chain. Samsung's parts system later revised DA41-00404D into DA41-00614F. This listing sells the board labeled DA41-00404D, so match what your own sticker reads: if it says DA41-00404D, this is your board. If it reads DA41-00614F or DA92-00047A, order that number instead.
Is DA41-00404E the same board as DA41-00404D?
It is a neighboring number in the same inverter family, but the published record does not state how the two divide. No catalog we checked spells out what separates a D from an E on this board, so we are not going to guess. Go by exactly what your board's own sticker reads rather than assuming a nearby letter is close enough.
What is DA92-00047A? Is that the same board too?
It is on the same lineage, not the same part. DA92-00047A is listed as an earlier number on the same chain that Samsung consolidated into DA41-00614F, alongside DA41-00404D. If your sticker reads DA92-00047A, order under that number; this listing sells the board labeled DA41-00404D.
Which Samsung refrigerator models use the DA41-00404D?
No catalog we checked publishes a model list tied to this exact number. Without a published list we are not going to present someone else's fitment as this part's own. Match the number on your board's own label instead.
My compressor won't start but the panel still lights up. Is this the board?
That pattern, a live panel with a compressor that never tries to start, is what this board causes once the cheaper checks are clear. Have a qualified technician confirm house power reaches the board at CN75, and check that the connectors nearby are solid, before you order.
Does the DA41-00404D need programming after I install it?
No source we checked documents any programming, pairing or setup step for this board. Treat it as an unplug, swap and reconnect job. Give the refrigerator a few hours at its normal setting before you judge the repair.
