DA92-00111B Samsung Refrigerator Inverter Board, When Everything Runs Except the Cold
Part DA92-00111B is the inverter board that powers the compressor on Samsung's RF18HFENB and RF20HFENB French-door bottom-freezer refrigerators, along with a range of RF263 through RF268 French-door and RS263 through RS267 side-by-side models. The lights come on, the fans turn, the display looks normal, and yet neither compartment gets cold: that is the signature of an inverter that has stopped driving the compressor. One important note up front: despite sharing several model listings, this is not the same part as the DA92-00047A, and the two are not documented substitutes for each other. This guide shows you how to confirm which board your unit actually has, rule out the compressor and the free stuff first, and order the right part once.
Why Is My Samsung Refrigerator Running but Not Cooling? DA92-00111B Inverter Symptoms
Common symptoms associated with a failing DA92-00111B Samsung inverter board include warm fresh food and freezer compartments while lights, fans, and the display continue working, a compressor that stays silent or runs only in short bursts, sporadic cooling with random shutdowns, a status LED on the board that stays dark or flashes, clicking near the compressor area, and cooling loss that follows a power surge or outage.
The pattern to look for is a refrigerator that behaves normally in every visible way while quietly losing its cold. If several of the following match your unit, the inverter board deserves a close look, but read the full rule-out section before ordering, because the compressor itself can produce identical behavior.
- Fresh food and freezer compartments both warming while lights, display, and fans behave normally
- The compressor stays silent, or attempts to run and drops out within moments
- Cooling comes and goes sporadically, with shutdowns that follow no pattern
- The status LED on the inverter board stays dark, or flashes instead of holding steady
- Clicking from the machine compartment as the system tries to start the compressor
- The trouble started right after a power surge, outage, or electrical storm

How Do I Confirm Which Inverter Board My Samsung Refrigerator Has? Watch the Video
Samsung used more than one inverter board across the models this part serves, so the label on the board itself is the only reliable identifier. Unplug the refrigerator, open the rear machine compartment, find the board near the compressor, and read the service number on its label. If it reads DA92-00111B or a listed cross-reference, this is your part. If it reads DA92-00047A, you need that board instead, and we carry both.
This short video shows how to locate and read the part number sticker on an appliance control board and how to confirm you have the right part before opening the packaging. The same method applies to the DA92-00111B. Because Samsung fitted different inverter boards to the same refrigerator models across production runs, checking this label matters more for this part than for most. General installation guidance is included in the Quick Start Guide shipped with every order.
Samsung Inverter Board Symptoms, Reading What the DA92-00111B Is Telling You
The most commonly reported signs of DA92-00111B failure are a warm refrigerator with normal lights and fans, a compressor that receives no drive output, and a status LED that is dark or flashing. A compressor that runs warm while the cabinet stays at room temperature points away from the board toward the sealed system, and an OF OF display is demo mode rather than any fault.
Work through the table below to narrow things down before spending anything. Because the inverter and the compressor operate as a matched pair, a few of these rows can be caused by either component, and the checks in the rule-out section separate them.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Warm compartments, everything else normal | No drive output reaching the compressor | Put a hand near the compressor. If it is cool and silent while the fans run, the inverter board is a commonly reported cause. Look at the board's status LED next. | Common |
| Compressor tries to start, then quits | Start attempt failing on the board side or the compressor side | Reseat the compressor plug, then test the compressor windings as described below. Balanced windings with a persistent start failure are commonly associated with the board. | Board or compressor |
| Status LED on the board stays dark | Board not receiving supply power, or board failed | Verify the refrigerator has power and the connectors at the inverter are seated. Supply confirmed plus a dark LED is a commonly reported board failure. | Common |
| Status LED flashing | Board reporting a fault in the compressor circuit | A flashing LED tells you the board sees a problem, but not which side it is on. Test the windings and the outlet voltage before deciding between board and compressor. | Board or compressor |
| Compressor runs warm, cabinet never cools | Refrigerant or sealed system fault, not electronics | A running compressor means the inverter is delivering power. Persistent warmth despite hours of runtime points to the sealed system, which needs a licensed technician. | Usually not the board |
| Cooling died right after a surge or outage | Surge damage to the inverter is commonly reported | Unplug the unit for one full minute, restore power, and give it time to restart. If cooling does not return, the inverter board is a commonly reported casualty of surges. | Possible |
| Display reads OF OF or O FF | Demo mode, which disables cooling on purpose | This is a setting, not a failure. Exit demo mode using the button combination listed in your owner's manual before doing any further diagnosis. | Not the board |
Samsung Error Codes and the DA92-00111B, What the Display and the Board LED Can Tell You
Samsung refrigerators using the DA92-00111B report compressor-circuit trouble through display codes including 83E for abnormal compressor current, 84C for a locked compressor, 85E for under-voltage, and 86E for over-voltage, while 88 88 indicates power was interrupted during startup and OF OF indicates demo mode. The board also carries a status LED, but no published blink-count chart specific to the DA92-00111B was found in our research, so LED patterns should be treated as a general fault indicator rather than a decoded message.
A quick honesty note before the table: blink-count charts circulate online for older Samsung inverter boards, but we could not confirm any published chart that applies specifically to this board revision. Rather than guess, treat the LED as a simple health indicator and lean on the display codes and physical checks. Every code below should be preceded by a one-minute unplug reset, since a code that clears and stays gone needs no parts at all.
| Code / Signal | What It May Indicate | Is It This Board? |
|---|---|---|
| Board LED steady | The inverter is powered and delivering drive output. If cooling is still absent with a steady LED and a warm running compressor, look downstream at the sealed system. | Board likely OK |
| Board LED dark | Either no supply is reaching the board or the board has failed. Confirm the connectors and incoming power before condemning it. | Board-related |
| Board LED flashing | The board has detected a compressor-circuit fault. Without a confirmed blink chart for this revision, use it as a prompt to test the windings and voltage rather than a diagnosis by itself. | Board or compressor |
| 83E | Abnormal current detected in the compressor circuit, commonly following a surge. Can originate on either side of the pair, so test the compressor before ordering. | Board or compressor |
| 84C | Compressor reported as locked. A seized compressor is the commonly reported cause, so have the compressor evaluated before replacing electronics. | Check compressor first |
| 85E | Supply voltage sagging below normal. Rule out the outlet, extension cords, and shared circuits. Recurring low-voltage reports on a healthy outlet are commonly associated with the board. | Possible |
| 86E | Supply voltage running above normal, commonly logged during surges. Same outlet checks apply, and surge-related failures commonly land on the inverter. | Possible |
| 88 88 | Power was disrupted while the unit was booting. Unplug for one full minute and restore power. If the display returns to normal and stays there, nothing needs replacing. | Usually not the board |
| OF OF / O FF | Demo or cooling-off mode, a setting rather than a fault. Exit it per your owner's manual before troubleshooting further. | Not the board |
Will the DA92-00111B Fix My Samsung Refrigerator? What to Check Before Ordering
The DA92-00111B commonly resolves Samsung refrigerator faults where the compressor receives no drive output while lights, display, and fans work, where the board's status LED is dark with supply power confirmed, and where cooling failed after a surge with healthy compressor windings. Before ordering, rule out demo mode, the restart delay after a power interruption, supply voltage at the board, the compressor windings, and loose connectors, each of which can imitate an inverter failure for free.
Two free checks come first. A unit switched into demo mode shows OF OF and will never cool regardless of what parts go in. Separately, Samsung platforms commonly hold the compressor off for several minutes after power is restored, so a compressor that has not started two minutes after a reset has not failed anything yet.
The inverter can only be judged if it is actually being fed. Line voltage reaches this board through the main control board and harness, so a dark status LED is just as consistent with a missing supply as with a dead inverter, and replacing the board will not fix a harness fault.
An inverter-driven compressor with a damaged winding produces the same silence and the same fault indications as a failed board, and no replacement inverter can revive it. The winding check takes minutes and is the most valuable single test before spending money on this repair.
Vibration and service work loosen connectors over time, and a partially seated compressor plug or supply connector reproduces an inverter failure convincingly. Cases resolved by simply reseating connections are commonly reported on this platform.
Can I Replace the DA92-00111B Myself? Difficulty and Time Estimate
Replacing the DA92-00111B is a moderate DIY repair commonly completed in 30 to 45 minutes with a Phillips screwdriver. The board lives in the machine compartment at the rear of the refrigerator, near the compressor, so the unit must be pulled out from the wall. The most commonly reported installation error is a compressor plug that is not pressed fully home, which recreates the original no-cooling symptom on a brand-new board.
This is a manageable repair for a careful DIYer. Access comes from the rear: pull the refrigerator out, remove the machine compartment cover, and the board is mounted near the compressor. The connectors do the real work here, so photograph everything before touching it and press each plug home until it clicks on reassembly. Anyone uncomfortable working around line voltage and the compressor should hand this to a qualified appliance technician without hesitation.
Does the DA92-00111B Fit My Samsung Refrigerator? Compatibility Check
To confirm the DA92-00111B fits, read the label on the inverter board in your refrigerator's machine compartment and match it to DA92-00111B or a listed cross-reference such as AP5582584 or PS4167963. Model lookups alone are unreliable for this part because Samsung fitted different inverter boards, including the DA92-00047A, to the same base models across production runs, and the RF23 and RF28 platforms use different boards entirely.
Model Number Check
Enter your refrigerator's model number to check it against our DA92-00111B compatibility records. Not found? Use the buttons below to reach our team directly.
Samsung fitted more than one inverter board to several of these refrigerator models depending on production date, so two units with the same model number can carry different boards.

Which Samsung Refrigerator Models Use the DA92-00111B Inverter Board?
Part DA92-00111B is used in Samsung RF18HFENB and RF20HFENB French-door bottom-freezer refrigerators, RF263, RF266, RF267, and RF268 French-door models, and RS263, RS265, and RS267 side-by-side models, typically with a /XAA suffix in North America. Several of these base models were also built with the DA92-00047A in other production runs, so the board label, not the model number, is the final word. RF23, RF28, and RFG-series models use different boards.
RF18 / RF20 Series, French Door Bottom Freezer
RF263 / RF266 Series, French Door
RF267 / RF268 Series, French Door
RS263 / RS265 / RS267 Series, Side-by-Side
Models are listed in base form; North American units typically carry a /XAA suffix and a revision number. This list is compiled from cross-reference data and is provided as general guidance only. Several base models here were built with the DA92-00047A inverter in other production runs, and the RF23, RF28, and RFG 4-door platforms use entirely different board families, so always confirm by reading the label on the board in your machine compartment. If your model is not listed or the label is unclear, contact our team and we will verify before you buy.

Is It Worth Repairing My Samsung Refrigerator? What the DA92-00111B Costs vs Your Alternatives
Replacing the DA92-00111B inverter board costs a small fraction of a comparable new Samsung French-door refrigerator, which commonly runs $1,400 to $2,300, and substantially less than a technician-installed board replacement, which commonly runs $400 to $750. For a refrigerator that is healthy apart from its inverter, the board is the economical path by a wide margin. Figures are general estimates and vary by region and provider.
What your options typically cost
Samsung Refrigerator Still Warm After Replacing the Inverter Board? Start Here
The most commonly reported reasons a Samsung refrigerator stays warm right after a DA92-00111B replacement are judging the unit before the post-reset restart delay has passed, a compressor plug or supply connector that did not seat fully, a latched display code that clears with a one-minute unplug, insufficient pull-down time, and a compressor that had already failed, which no inverter board can compensate for.
Let the restart delay finish
Samsung platforms commonly keep the compressor off for several minutes after power returns, so silence right after the swap is expected behavior, not evidence of a bad board. Do a full one-minute unplug to clear any latched code, restore power, and only then start the clock.
Press every connector fully home
The compressor plug is the most commonly reported culprit on this repair. A plug resting in place without clicking produces the identical no-cooling symptom the old board was blamed for, and it happens to careful people regularly.
Check the status LED before anything else
The LED on the new board is your fastest feedback. Steady commonly means the board is powered and driving; dark means check supply and connections; flashing on a fresh board commonly points back at the compressor circuit rather than the new part.
Give the cabinet real time to pull down
A refrigerator that has been warm for days needs hours of continuous running before the compartments feel cold again, and the ice maker follows later still. Judging the repair inside the first hour leads to unnecessary returns of working boards.
Guard the board against static
Electronics can be damaged by static before they are ever powered up. Touch bare metal on the refrigerator chassis before handling the board, keep it in its bag until the moment of installation, wear the included install gloves, and grip by the edges.
Still not working after all of the above?
Contact our team before returning anything. A brief conversation resolves the majority of post-install situations. We stand behind every board we sell and are here to help you get the result you need.
Other Samsung Refrigerator Parts That May Need Attention
Components that commonly fail alongside or instead of the DA92-00111B include the inverter compressor it drives, the main control board that feeds it power and commands, the evaporator and condenser fan motors, and the compartment and defrost sensors. Ruling each out first prevents replacing a healthy board.

DA92-00111B Samsung Refrigerator Inverter Board, Frequently Asked Questions
Common questions about the DA92-00111B cover whether it can substitute for the DA92-00047A, why both boards appear in lookups for the same refrigerator model, whether it fits RF23 and RF28 units, whether it is discontinued, what the letter suffixes on Samsung model numbers mean, what a flashing board LED means on this revision, and how to tell a failed inverter from a failed compressor.
Can I use the DA92-00111B in place of a DA92-00047A, or the other way around?
Treat them as different parts. No Samsung documentation we could verify lists either board as a substitute or successor for the other, even though their model coverage overlaps. The correct board for your unit is whichever number is printed on the board already installed in your machine compartment. We stock both, and our guide for the DA92-00047A covers that board's models and diagnostics separately.
Why do parts lookups show both the DA92-00111B and the DA92-00047A for my exact model?
Samsung made running production changes, and the same base model built in different periods can carry different inverter boards. Parts databases list every board ever associated with the model, which is technically accurate and practically confusing. The fix is simple: ignore the competing lookup results and read the label on your actual board, since that is the part your specific unit was built with.
Does the DA92-00111B fit RF23 or RF28 refrigerators?
No. Those newer platforms use later inverter board families with their own part numbers, and this board is not among them. The RFG-series 4-door models are also outside this part's coverage. If your model starts with RF23 or RF28, send us the number from the board in your machine compartment and we will identify the correct part for it.
Is the DA92-00111B discontinued like the DA92-00047A?
Not in the same way. The DA92-00047A has been discontinued by Samsung outright, while the DA92-00111B still moves through parts supply channels as of 2026, though availability swings noticeably between suppliers. A FailSafe Certified board with a 1-year warranty removes the availability lottery from the equation either way.
What do the letters at the end of my model number mean, like SR versus WW or AC versus AB?
The trailing letters mostly encode the finish, for example SR for stainless and WW for white, and sometimes a production revision, as with RF268AB versus RF268AC. Compatibility can differ between those revision letters even within one series, which is why the list on this page includes specific suffixes rather than whole families. Match your full model number, then confirm with the board label.
My board's LED is flashing a pattern. What is the code?
For this specific board revision, we could not verify any published chart that maps blink counts to faults, and we will not invent one. What the flashing reliably tells you is that the board has detected a compressor-circuit problem. Turn that prompt into real information with two checks: the compressor winding test and an outlet voltage check. Balanced windings and clean power with a persistent flash shift the odds toward the board itself.
How do I know whether my compressor or my inverter board failed?
The winding test is the separator. Unplug the unit, pull the plug off the compressor's three terminals, and measure resistance across each pair. Three closely matched readings suggest the compressor's windings are intact, which moves suspicion to the board. An open pair, a shorted pair, or one reading wildly different from the others condemns the compressor, and in that case a new inverter board would be money spent on the wrong part.
