W10790783 Whirlpool Refrigerator LED Driver Board, Interior Lights Out, Dim or Flickering on Built-In and French Door Models
Your refrigerator is still cold, but you are reaching into a dark cabinet. Part W10790783 is the low-voltage LED driver board that feeds the interior light modules on a large family of Whirlpool, KitchenAid, Maytag, Jenn-Air and Kenmore refrigerators, from the KBSD and KBSN built-in columns and JS42 and JS48 Jenn-Air built-ins to the WRX986, WRX988, MFT2776 and MFX2876 French door models. It is not the main control board and it has nothing to do with cooling. This guide covers what the board does, how to separate a driver fault from a failed light module or a door switch, which number is supplied today, and how to confirm fit before you order.
Why Are the Interior Lights Out on My Whirlpool Refrigerator? LED Driver Board Symptoms
Symptoms commonly associated with a failing W10790783 LED driver board include interior lighting that stays dark in every compartment while cooling continues normally, a faint pink or partial glow instead of full brightness, rapid blinking or flicker across the cabinet, and lights that return for a short time after the refrigerator is unplugged and plugged back in. Because this board only supplies the lighting circuit, temperature and ice production are typically unaffected.
The signature of a driver board fault is lighting trouble with everything else working. Your food stays cold, the display responds, the ice maker runs, and only the lights misbehave. If your refrigerator matches one or more of the descriptions below, this board is worth investigating, but work through the rule-out section first, because a door switch or a single failed light module produces very similar results.
- Cabinet stays dark when a door opens while cooling and the display work normally
- Lights come up faint, pink, or partially lit instead of reaching full brightness
- Rapid blinking or flicker across several lighting positions at the same time
- Lighting works again for a few minutes or a few days after a power cycle, then quits
- Replacement light modules keep failing within weeks or months of being fitted
- Lighting drops out when the cabinet warms up and returns when it is cool

How Do I Read the Part Number on a Whirlpool LED Driver Board? Watch the Video
The number on a Whirlpool LED driver board is printed on a label applied to the board itself, not on the appliance model plate. To verify the W10790783, disconnect power, reach the board through the upper interior access panel on your model, and compare the printed label to W10790783 or to one of its interchange numbers such as W10830288 before ordering.
This short video shows how to find and read the part number label on an appliance control board, and how to check it against what you have ordered before the packaging is opened. The same approach applies here. One caution specific to this repair: a refrigerator can hold both a lighting driver board and a separate main control board, and their labels look alike, so read the number carefully rather than going by board size or position. Installation guidance is included in the Quick Start Guide shipped with every order.
Whirlpool Refrigerator Lighting Faults, What Each Pattern Points To
The W10790783 LED driver board reports nothing to the display, so it is diagnosed by pattern rather than by code. Lighting that fails across multiple positions at once, comes up dim or pink everywhere, or blinks rapidly commonly points at the driver. Lighting that fails behind one door only, or one position at a time, commonly points at a door switch or an individual light module instead.
Read the table below as a first sort, not a verdict. Two things make this repair easy to get wrong. The light modules on these cabinets are connected in runs rather than individually, so one bad module can pull down everything downstream of it. And a driver board that is failing under load can destroy the modules you just fitted, which is why some owners replace the same light two or three times.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Nothing lights up anywhere, cooling normal | No low-voltage output reaching the light runs | Confirm the door switches respond, then have the board's low-voltage output checked with a door held open. Supply present with no output is the pattern most commonly attributed to the driver. | Common |
| Everything glows faint or pink | Weak driver output, or one degraded module loading the run | Partial illumination across the whole cabinet is commonly reported with this board. Modules in the affected run should still be checked before the board is condemned. | Board or module |
| Rapid blinking across several positions | Unstable low-voltage supply | Reseat the plugs at the board and at the light runs first. Blinking that survives a reseat and affects more than one position is commonly linked to the driver. | Common |
| Lights return after unplugging, then quit again | Intermittent driver output under thermal load | A fault that clears on a power cycle and returns later is commonly reported on this board. Note how long it takes to come back, since that helps a technician confirm the pattern. | Board-related |
| One position dark, the rest normal | Open light module in that run | A single dark position with the rest of the run lit is usually the module, not the driver. Modules pry out of the liner and unplug behind, so they can be swapped for a known good one to confirm. | Usually a module |
| Dark behind one door only | Door switch for that door | Operate each door's switch by hand and compare. If the cabinet lights from one door and not another, the driver is doing its job and the switch is the suspect. | Not the board |
| New light modules keep burning out | Upstream supply fault damaging the modules | Repeat module failures in the same positions are a recognised sign of a supply problem rather than bad modules. Have the driver output checked before fitting another module. | Board-related |
Is There an Error Code for Refrigerator Lighting? What the Display Will and Will Not Tell You
There is no dedicated display code for the interior lighting circuit or for the W10790783 LED driver board on these refrigerators. Lighting faults are diagnosed by pattern and by measuring the board's low-voltage output, not by reading the panel. A blank display during a lighting failure is normal and neither confirms nor rules out the driver board.
This is the single most useful thing to understand before you spend money here. Codes shown on these refrigerators cover temperature, sensors, communication and defrost, and a lighting circuit is simply not part of what gets monitored. Diagnostic and service modes exist on most of these models, but the entry sequence differs between the built-in columns and the French door cabinets and between production revisions, so follow the instructions for your model rather than a sequence borrowed from another. The table below covers what people commonly see and what it actually indicates.
| What You Observe | What It May Indicate | Is It This Board? |
|---|---|---|
| No code at all, lights dead | Expected behaviour. The lighting circuit is not monitored by the display, so nothing will appear. Diagnose by pattern and by low-voltage output instead. | Diagnose by pattern |
| Power interruption indicator | Records that incoming power was lost. Clear it per your model's instructions. It refers to the supply, not to the lighting driver. | Not the board |
| Showroom or demonstration setting active | Some of these refrigerators ship with a display or demonstration setting that suppresses normal operation. Confirm it is off before troubleshooting the lights. | Not the board |
| Sabbath setting active | Interior lighting is held off on purpose while this setting is enabled. Exit it per your model's instructions and retest. | Not the board |
| Temperature or sensor codes present | These belong to the cooling and control system. The lighting driver does not generate them and replacing it will not clear them. | Not the board |
| Display dead as well as the lights | Losing the panel and the lighting together points upstream to the supply or to the main control system rather than to a dedicated lighting driver. | Usually elsewhere |
| Low-voltage output check, for technicians | With a door held open, line voltage should be present at the board's input and a low-voltage direct current output should be present at the connector feeding the light runs. Readings in the range of roughly ten to fourteen volts direct current are commonly reported. Input present with no output is the reading most commonly associated with driver failure. | Board if no output |
Will the W10790783 Bring My Lights Back? What to Rule Out Before Ordering
The W10790783 commonly resolves lighting faults where the whole cabinet stays dark, glows faint or pink, or blinks across several positions while cooling is unaffected, and where the board has input voltage but no low-voltage output. Before ordering, rule out the door switches, the individual light modules in each run, the lighting harness and plugs, and any special display setting, because all four can imitate a driver board failure.
Across these platforms the door switch is the most frequently reported cause of a refrigerator that will not light, well ahead of any board. Each door has its own switch, so a failure leaves one section dark while everything else behaves. It costs nothing to check and is far cheaper than a board.
The light modules in these cabinets are chained rather than fed individually, so one open module leaves everything after it dark and one shorted module can drag the entire run down. This is the most common reason a new driver board appears not to have fixed anything, and it is why a whole cabinet can go dark from a single failed part.
Every light run reaches the driver through plug connectors, and on the French door cabinets part of that path travels through the door hinge area. A plug that has backed out, a pin that has lost tension, or a pinched conductor produces flicker and dead sections that look exactly like a driver fault.
Several of these refrigerators include settings that deliberately suppress interior lighting. A unit bought as a floor model, or one where a setting was entered by accident, can present as a total lighting failure with nothing actually broken. This is the cheapest possible outcome and it is worth thirty seconds of checking.
Can I Replace the W10790783 LED Driver Board Myself? Difficulty, Time and Access
Replacing the W10790783 is a moderate repair that most confident do-it-yourself owners complete in 30 to 45 minutes with a nut driver, a Phillips screwdriver and a plastic pry tool. The board is mounted in the upper section of the cabinet behind an interior access panel, so trim has to come off before the board is reachable. Access differs between the built-in columns and the French door cabinets.
The work itself is straightforward once the board is exposed. Getting there is the part that takes the time, because the driver sits in the upper section of the cabinet behind an interior access panel and the trim around it is held by clips as well as screws. Access varies by platform, so check the parts diagram for your exact model before you start rather than assuming the built-in and French door layouts match. Photograph every plug before removing anything, and work with the refrigerator unplugged. If you are not comfortable prying interior trim or handling electronics, a qualified appliance technician is the right call.
Does the W10790783 Fit My Refrigerator? Compatibility Check
To confirm the W10790783 fits, match the label on your existing LED driver board to W10790783 or to one of its interchange numbers, which include W10635302, W10814803, W10830288, W11113852 and W11185975. The board is used across KitchenAid KBSD and KBSN built-ins, Jenn-Air JS42 and JS48 built-ins, Whirlpool WRX and WRF French door models, Maytag MFT and MFX models and several Kenmore 596 numbers. Model lookups help, but the label on the board is the reliable check.

Is a Dark Refrigerator Worth Fixing? What the W10790783 Costs Against the Alternatives
Replacing the W10790783 LED driver board is typically a small fraction of the cost of a comparable new built-in or French door refrigerator, which commonly runs $2,500 or more for the platforms this board serves, or of a technician visit for a lighting fault, which commonly runs $250 to $500 including parts. Figures are general estimates and vary widely by region and provider.
What your options typically cost
Lights Still Out After Fitting the New LED Driver Board? Start Here
The most commonly reported reasons interior lighting stays dark after a W10790783 LED driver board replacement are a failed light module still sitting in the run, a plug that is not fully seated at the board or at a light position, a door switch that had failed at the same time, and a showroom or Sabbath setting that was never switched off.
Power cycle before judging anything
Leave the refrigerator unplugged for a couple of minutes after the board is in, then restore power and open a door. A clean restart clears a share of post-install situations on its own and costs nothing to try.
Reseat every plug you touched
A connector that looks home but has not clicked fully will reproduce the original fault exactly. Work back through each plug at the board and at every light position you disturbed, pressing until each seats positively.
Check the light modules in the affected run
This is the leading reason a new board looks like a dud. Because the modules are chained, one that failed alongside the board will keep its whole run dark no matter how good the new driver is. If some positions came back and others did not, the modules are where to look next.
Confirm the door switches independently
A switch can fail in the same period as a board, and the two faults hide each other. Operate every door switch by hand and compare the response from each door before concluding anything about the new board.
Rule out a showroom or Sabbath setting
If a special display setting was enabled at any point, the lighting stays off by design and no board will change that. Check the control panel and exit the setting using the instructions for your model.
Handle the board by its edges with the install gloves
Static discharge is a common way replacement electronics are damaged during fitting. Touch the metal cabinet frame before you pick the board up, wear the included install gloves, and hold the board by its edges only.
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 Refrigerator Lighting Parts Worth Checking
Components that commonly fail alongside or instead of the W10790783 include the interior LED light modules and service kits, the door switches, the lighting harness and its hinge routing, and the main control board that supplies the lighting driver. Each produces symptoms close enough to a driver fault that ruling them out first reduces the chance of buying the wrong part.

W10790783 Whirlpool Refrigerator LED Driver Board, Frequently Asked Questions
Common questions about the W10790783 cover which of its several interchange numbers to order, why a whole cabinet can go dark from one failed light, why the display shows no code, whether this board has anything to do with cooling, why replacement light modules keep failing, and how the built-in and French door versions of this repair differ.
My board says W10790783 but the part I am offered says W10830288. Is that the same thing?
Yes. W10790783 is one of several numbers used for the same LED driver board over its production life, and W10830288 is the number the manufacturer supplies it under today. The wider interchange family includes W10635302, W10814803, W11113852 and W11185975, along with the retailer references AP6004427 and PS11737860. Parts databases uniformly treat all of these as one interchangeable board, although they do not agree on the order in which the numbers replaced one another. What matters for ordering is that the number on the board you are removing appears somewhere in that family.
Every light in the refrigerator is dead. Does that automatically mean the driver board?
Not automatically, and this is where money gets wasted. The interior modules on these cabinets are chained rather than wired individually, so a single failed module can leave everything downstream of it dark and produce exactly the same total blackout as a dead driver. Before ordering, operate every door switch by hand, then have the board's low-voltage output checked with a door held open. Input voltage present with no output is the reading that points at the driver. Output present with the cabinet still dark points back at the modules or the harness.
My display shows no error code at all. Does that rule the board out?
No, and it does not rule it in either. These refrigerators do not monitor the lighting circuit, so a lighting failure produces no code by design and a blank display tells you nothing about this board. Any codes you do see relate to temperature, sensing, communication or defrost and belong to other systems. Diagnostic and service modes exist on most of these models, but the entry steps vary between the built-in and French door platforms and across revisions, so use the instructions for your model rather than a sequence found for a different one.
Can a failed LED driver board stop my refrigerator from cooling?
No. This board serves the lighting circuit only. Cooling, defrost, compressor operation, temperature sensing, the user interface and the ice maker are handled by other boards in the cabinet. If your refrigerator is warm as well as dark, the lighting driver is not the explanation and you should be looking at the main control system instead. The reverse is also worth knowing: a refrigerator that cools perfectly and only fails to light is a strong fit for this repair.
I have already replaced the light itself twice and it keeps dying. What is going on?
Repeat module failures in the same position are a recognised sign that the problem is upstream rather than in the module. A driver board that is delivering unstable or out-of-range output will keep destroying whatever module is fitted to it, so the fault looks like bad replacement parts when it is actually the supply. If you have fitted more than one module to the same position and it has failed again, have the driver output measured before buying a third.
The built-in and the French door versions of this repair look different. Is it the same job?
It is the same board doing the same work, but the access is not comparable. On the built-in columns the driver sits behind an upper interior panel that has to be released before you can reach it, and on the French door cabinets the layout and the trim differ again. Neither platform documents this board in the owner literature, so check the parts diagram for your exact model before starting, photograph every plug, and expect the access to take longer than the swap itself.
