W10788814 Whirlpool Refrigerator LED Power Board, The Fix for Interior Lights That Are Out, Dim, or Flickering
The food is cold but you are reaching into a dark refrigerator. Part W10788814 (now supplied under its superseding number W10804160) is the LED power board that supplies and regulates the interior lighting on Whirlpool and KitchenAid 5-door French-door refrigerators, including the WRV976, WRV986, WRV996, KRMF606, and KRMF706 series. When this board fails, lights can go out across the whole cabinet, flicker, or dim. This guide will help you confirm whether this is your board, separate it from a failed LED module or door switch, and order with complete confidence.
Why Are My Whirlpool Refrigerator Lights Out, Dim, or Flickering? LED Power Board Symptoms
Common symptoms associated with a failing W10788814 Whirlpool LED power board include all interior lights going out at once in the refrigerator, drawers, and freezer, lights flickering in both compartments, lights that are noticeably dim, and lighting that fails to come on when a door opens. Because the board powers every lighting zone, a fault that affects several zones together is the signature, while a single dark zone more commonly points to an LED module.
If your Whirlpool or KitchenAid refrigerator is showing one or more of the following, the LED power board is a common area to investigate. Cooling is normally unaffected, since this board has nothing to do with the compressor or temperature control. Read through the full diagnosis section below before ordering, because failed LED modules and door switches produce very similar results.
- All interior lights out at once, in the fresh food section, the drawers, and the freezer
- Lights flickering in both the refrigerator and freezer compartments
- Lights noticeably dim, sometimes getting dimmer over weeks or months
- Lights fail to come on when a door is opened, then may work on a later opening
- Lights briefly return after unplugging the refrigerator, then fail again
- A faint buzzing or electrical noise from the lower rear of the unit

How Do I Find the Part Number on My Whirlpool LED Power Board? Watch the Video
The part number on a Whirlpool LED power board is printed on a label on the board, which is located in the circuit board housing at the lower rear of the refrigerator, behind the rear access panel. To verify the W10788814, unplug the refrigerator, pull it out, remove the rear access panel, and compare the label to W10788814, W10676677, or W10804160 before ordering.
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 W10788814, which sits in the lower rear circuit board housing alongside other boards, so compare the label carefully to make sure you are reading the LED power board and not a neighboring board. General installation guidance is included in the Quick Start Guide shipped with every order.
Whirlpool Refrigerator Lighting Symptoms, What Each One Points To
The W10788814 Whirlpool LED power board does not display an error code. It is diagnosed by which lighting zones are affected and how. Several zones failing, flickering, or dimming together commonly points to the board, while a single zone that is dark, or zones dropping out one at a time over months, commonly points to an individual LED module in a series-wired string. Each symptom below points toward a likely cause and a recommended next step.
Use the table below as a starting point, not a definitive verdict. The interior LEDs on these models are wired in series strings, so one failed module can take down or dim its whole string and look like a board fault. Ruling out the modules and door switches first is always recommended.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Every light in the cabinet is out | Board output lost, or no supply reaching the board | Unplug for two minutes and retry. If nothing returns, confirm the board is receiving power from the main board and harness. Board failure is a commonly reported cause when supply is present. | Common |
| Lights flicker in both fridge and freezer | Unstable board output | Flicker across multiple zones at once is a commonly reported board signature. Check connectors for seating first, then the board. | Common |
| Lights are dim everywhere | Weak board output, or a degraded module dragging its string down | Can be either. Test individual LED modules before the board, since one failing module in a series string commonly dims the others. | Check modules first |
| Only one zone is dark (ceiling, a drawer, or the freezer) | Failed LED module in that zone's string | A single dark zone with others normal commonly points to a module, not the board. Identify the open module with a jumper or battery test per your service information. | Usually a module |
| Zones have dropped out one at a time over months | Modules failing in sequence | A cascading pattern commonly indicates individual modules rather than the board. Replace the failed modules; the board is usually fine. | Usually modules |
| Lights do not respond when one specific door opens | Door switch for that door | Press the switch by hand. If another door's switch triggers the lights normally, the board is working and the switch is the likely cause. | Not the board |
| Lights go off after the door has been open a while | Normal automatic shutoff | These models turn the lights off after roughly ten minutes with a door open. Close and reopen the door. Not a fault. | Not the board |
Is There an Error Code for Refrigerator Lighting on WRV and KRMF Models? What the Display Can and Cannot Tell You
Whirlpool WRV976, WRV986, WRV996 and KitchenAid KRMF606 and KRMF706 refrigerators do not display a dedicated error code for interior lighting or for the W10788814 LED power board. Lighting faults are diagnosed by zone pattern and by checking the board's output to the LED strings. A PO or power-outage indicator on the display relates to a supply interruption and does not point to the LED board.
Unlike compressor or sensor faults, a lighting failure on these models will not produce a diagnostic code on the dispenser display, so the absence of a code does not rule the board in or out. The short table below covers the display indications customers commonly ask about in connection with lighting, and what they actually mean.
| What You See | What It May Indicate | Is It This Board? |
|---|---|---|
| No code, lights out or flickering | Normal for a lighting fault on these models. The display does not monitor the LED power board. Diagnose by zone pattern and by checking board output, as described in the sections above and below. | Diagnose by pattern |
| PO or power outage indicator | A supply interruption was detected. Press a button to clear it. This relates to the incoming power and does not indicate an LED board fault. | Not the board |
| Sabbath mode shown on the display | Sabbath mode intentionally keeps the interior lights off. Exit it per your owner's manual before troubleshooting. | Not the board |
| Display dark along with the lights | A dead display plus dead lights commonly points upstream to the main control board or the power supply, not the LED power board by itself. | Usually the main board |
| Board output check (for technicians) | The LED power board delivers low-voltage DC to the LED strings, commonly reported around 12 volts DC at the output connector. Output present with lights still dark commonly points to the modules or harness; output absent with supply present commonly points to the board. | Board if no output |
Will the W10788814 Fix My Refrigerator Lights? What to Check Before Ordering
The W10788814 commonly resolves Whirlpool and KitchenAid 5-door lighting faults where every zone is out at once, where lights flicker in both compartments together, or where the board has no output with supply voltage confirmed. Before ordering, rule out the automatic ten-minute light shutoff, the door switches, the individual series-wired LED modules, and the harness connectors, since each can mimic an LED power board failure.
These refrigerators turn the interior lights off after a door has been open for about ten minutes, and Sabbath mode keeps them off intentionally. Either one looks exactly like a lighting failure to someone standing at the open door, and both cost nothing to check.
Each door has its own switch that tells the control system to light the cabinet. A failed switch leaves the lights off when that door opens, even though the LED power board is perfectly healthy. Nearby magnets or electronics on the door can also interfere with some switch types.
The LED modules in these cabinets are wired in series strings. A single failed or shorted module can dim or extinguish its entire string, and a shorted freezer module in particular has been reported to pull down the whole lighting output, which looks exactly like a failed board. Replacing the board does not fix a bad module, and this is the most common reason a new board appears not to work.
The LED power board connects to the main board and to the LED strings through several connectors, and the lighting harness also passes through the door hinges. A connector that has worked loose or a pin that has lost tension commonly produces intermittent lights, flicker, or a dead zone.
Can I Replace the W10788814 LED Power Board Myself? Difficulty and Time Estimate
Replacing the W10788814 is a simple to moderate DIY repair that most homeowners complete in 15 to 30 minutes with a quarter-inch nut driver and a small flat screwdriver. The board sits in the circuit board housing at the lower rear of the refrigerator, so the unit must be pulled away from the wall and the rear access panel removed. The board snaps into a plastic housing and has a small number of connectors.
Most DIY-confident homeowners complete this repair in under 30 minutes. The W10788814 LED power board sits in the circuit board housing at the lower rear of the refrigerator, behind the rear access panel and under a snap-on plastic cover, alongside other boards. You will need to pull the refrigerator away from the wall. Photograph the connectors before removing anything, and make sure you are swapping the LED power board and not a neighboring board. If you are not comfortable working with electronic components, a qualified appliance technician is always the right call.
Does the W10788814 Fit My Whirlpool or KitchenAid Refrigerator? Compatibility Check
To confirm the W10788814 fits your refrigerator, match the label on your existing LED power board to W10788814, W10676677, or W10804160, which are the same board across three part number revisions. The board is confirmed for Whirlpool WRV976, WRV986, and WRV996 and KitchenAid KRMF606 and KRMF706 5-door French-door models. Model lookups are a helpful starting point, but the label on your board is the reliable check.

What your options typically cost
Refrigerator Lights Still Out After Replacing the LED Power Board? Start Here
The most commonly reported reasons Whirlpool or KitchenAid refrigerator lights stay out after a W10788814 LED power board replacement are one or more failed LED modules in a series-wired string, a shorted freezer module pulling down the new board's output, a connector that is not fully seated, a door switch that has failed independently, and skipping the power reset after installation.
Perform the power reset
After installation, unplug the refrigerator for about two minutes and plug it back in so the control system restarts cleanly. This is the first step to try and resolves a share of post-install situations before any further troubleshooting is needed.
Check every connector at the board
A connector that appears seated but is not fully clicked in can produce the same dark or flickering result as the original failure. Disconnect each connector at the LED power board and firmly reseat it until it clicks before testing again.
Test the LED modules themselves
The single most common reason a new board appears not to work is that one or more LED modules had also failed. Because the modules are wired in series strings, one open module leaves its string dark and one shorted module can drag down the whole output. If only some zones returned, or everything is still dim, the modules are the next place to look.
Confirm the door switches
If the lights work from one door but not another, the switch on the non-responding door has failed independently of the board. This is easy to miss when the board and a switch fail around the same time.
Use the install gloves and handle by edges
Static discharge is a common cause of damage to replacement electronics during installation. Touch the metal refrigerator frame before picking up the board, use the included install gloves, and handle 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 Whirlpool Refrigerator Lighting Parts That May Need Attention
Components that commonly fail alongside or instead of the W10788814 include the individual LED light modules and module kits, the door switches, the lighting harness and connectors, and in rare cases the main control board that supplies the LED board. Each can produce symptoms similar to an LED power board fault, so ruling them out first reduces the chance of replacing the wrong part.

W10788814 Whirlpool Refrigerator LED Power Board, Frequently Asked Questions
Common questions about the W10788814 cover whether W10804160 and W10676677 are the same board, why only one lighting zone went dark, what it means when lights flicker in both compartments, whether a single LED strip can be replaced instead of the board, why the lights shut off after the door has been open, and what to check when a new board does not bring the lights back.
Is W10804160 the same board as W10788814 and W10676677?
Yes. W10676677 was the original number, W10788814 replaced it, and W10804160 is the current manufacturer number for the same LED power board. Any of the three may be printed on the label of the board in your refrigerator, and a board supplied under any of them is a direct replacement for the others. What matters is that the number on your existing board's label is one of these three.
Only the ceiling lights (or only the freezer lights) went out. Is that the board?
Usually not. On these 5-door models the LED modules are wired in series strings by zone, so a single dark zone with the others working normally commonly points to a failed module in that zone's string rather than the power board, which feeds every zone. The board becomes the leading suspect when several zones fail, flicker, or dim together. A technician can find the open module by jumpering across suspects or testing a removed module with a small DC source.
My lights flicker in both the refrigerator and the freezer, but the side lights are fine. Board or modules?
Flicker that appears in more than one compartment at the same time is a commonly reported LED power board signature, and this exact pattern has been resolved by a board replacement on these models. Before ordering, reseat the connectors at the board, since a loose plug can flicker too. If the flicker persists with the connectors secure, the board is the likely cause.
Can I just replace one LED strip instead of the whole board?
Yes, if a module is the problem. The manufacturer supplies the interior LEDs as replacement modules and kits for these models, and when only one zone is affected, a module is the more likely and less expensive fix. If every zone is out or flickering together and the modules test good, the board is the fix. Many lighting failures on these refrigerators involve a module, a board, or both, so diagnose the pattern before buying either.
The lights go off after the door has been open for a while. Is the board failing?
No. These refrigerators turn the interior lights off automatically after a door has been open for roughly ten minutes, to protect the LEDs and save energy. Closing the door and reopening it restores the lights. Sabbath mode also keeps the lights off intentionally. Neither indicates a fault with the LED power board.
Is there an error code I should see for a lighting problem?
No. WRV976, WRV986, WRV996, KRMF606, and KRMF706 models do not display a dedicated lighting or LED board code, so a blank display during a lighting failure is normal and tells you nothing either way. A PO indicator refers to a power interruption, not the lights. Lighting faults are diagnosed by which zones are affected and, for technicians, by checking the board's low-voltage output.
I replaced the board and the lights are still out or dim. What did I miss?
Most often, one or more LED modules had also failed. Because the modules are series-wired, an open module leaves its string dark and a shorted module, particularly in the freezer, can drag the whole system dim even with a new board installed. Perform the two-minute power reset, reseat every connector at the board, press each door switch by hand, then test the modules. If the new board has output and the modules and switches are good, contact our team before returning anything.
