🔧 Step-by-Step Repair Instructions

🔧 Step 1: Test LED light modules

  1. Open both the refrigerator and freezer doors fully to expose all interior lighting.
  2. Locate the LED light modules – there are typically 4-6 rectangular LED strip assemblies: two strips mounted on the ceiling of the fresh food compartment (left and right sides, approximately 2 inches from the back wall), one strip on the top freezer ceiling (centered, 3 inches from the back), and additional strips on side walls if equipped.
  3. Press the door switch button manually on the fresh food compartment – this is a white or gray plastic button located on the upper right side of the door frame, approximately 4 inches down from the top. The lights should turn on when pressed and off when released.
  4. Observe each LED module for illumination. Note which specific modules are not lighting up or are dimly lit.
  5. Remove the LED light cover from a non-functioning module by inserting a flat-blade screwdriver (5mm width) into the small slot on the right edge of the lens cover and twisting 45 degrees. The lens will unclip from 2 plastic tabs.
  6. Locate the wire harness connector at the right end of the LED strip – it’s a white 2-pin connector with one red wire and one black wire.
  7. Unplug the connector by gripping both sides between your thumb and forefinger, then pulling straight away from the LED strip with 5-10 pounds of force.
  8. Set a multimeter to DC voltage (20V range). Touch the red probe to the red wire terminal and the black probe to the black wire terminal while the door switch is pressed.
  9. A functioning circuit will read 12-14 volts DC. If voltage is present but the LED doesn’t illuminate, the LED module itself (part number W10515058) has failed and requires replacement.
  10. If no voltage is present, trace the wiring harness back to the main control board to identify connection issues.

🛠️ Step 2: Check control board connections

  1. Locate the main control board housed in a black plastic enclosure mounted on the upper right side of the refrigerator interior ceiling, approximately 3 inches from the right wall.
  2. Remove the control board cover by pressing the two release tabs on the front edge and pulling the cover straight down and forward. The cover measures roughly 8 inches wide by 4 inches deep.
  3. Identify the main control board, a green circuit board measuring approximately 6 inches by 4 inches with multiple wire harness connectors attached.
  4. Examine connector J1 (the largest connector on the left side) – a white 20-pin connector with wires in various colors including blue, yellow, red, and white.
  5. Press the release tab on connector J1 while pulling straight back with firm, steady pressure of approximately 5-10 pounds of force. The connector will release with a distinct click.
  6. Inspect the male pins inside the connector housing and the corresponding female pins on the board for any signs of corrosion (green or white powder), burn marks (black or brown discoloration), or bent pins.
  7. Check connector J2 (center position) – a smaller 8-pin gray connector. Press its release tab and disconnect using the same technique as J1.
  8. Inspect connector J3 (right side) – a 4-pin white connector, and disconnect by pressing the top release tab.
  9. Reconnect J3 first by aligning the connector with its socket and pushing straight in until you hear and feel a definite click. The connector will be flush against the board surface.
  10. Reconnect J2, ensuring the connector alignment key (a small raised ridge on one side) matches the socket before pushing until it clicks.
  11. Reconnect J1, verifying all 20 pins align properly before applying pressure. Push until the release tab locks with an audible click.
  12. Verify each connection by attempting to pull each connector away – properly seated connectors will not move.

⚙️ Step 3: Inspect wiring harness

  1. Locate the main wiring harness running vertically along the right interior wall of the refrigerator compartment, approximately 2 inches from the edge.
  2. Trace this harness from the top control panel down to the compressor compartment at the bottom rear, identifying all connection points along the 68-inch length.
  3. Examine the first connector located 8 inches below the control panel—this is a white 6-pin connector with wires colored red, blue, yellow, black, white, and green.
  4. Check each wire where it enters the connector for cracks, discoloration, or exposed copper. Discoloration appears as brown or black marks on the insulation.
  5. Flex each wire gently at the connector entry point through a 45-degree arc. Damaged insulation will crack or split when flexed.
  6. Move down to the middle section connector positioned 34 inches from the top, behind the second shelf. This black 4-pin connector serves the ice maker system.
  7. Look for white crusty buildup or green corrosion on the metal pins inside both male and female sides of this connector. Corrosion indicates moisture intrusion.
  8. Continue to the bottom harness connection in the compressor compartment, accessing through the lower rear panel. Remove the 4 Phillips-head screws (#2 screwdriver) securing this panel.
  9. Inspect the final connector—a gray 8-pin connector located 3 inches above the compressor housing on the right side.
  10. Check for heat damage on wires within 6 inches of the compressor. Heat-damaged insulation appears brittle, darkened, or melted.
  11. Examine all wire routing clips (7 total along the harness path). Broken clips allow wires to contact sharp metal edges or moving parts.
  12. Verify no wires are pinched between cabinet panels or trapped under shelves by running your finger along each wire’s full length.

🔩 Step 4: Replace faulty LED modules

  1. Locate the failed LED module by identifying which section of the refrigerator or freezer has non-functioning lighting (common locations are ceiling-mounted in the fresh food compartment, upper rear wall 2 inches from the top, or left side wall 8 inches from the top in the freezer).
  2. Remove the LED light cover by gripping it at both ends and pulling straight down with firm pressure until the two plastic clips (located at each end of the cover) release from their slots.
  3. Identify the LED module mounting screws—you’ll see 2 Phillips-head screws on either side of the rectangular LED housing, positioned approximately 1 inch from each end.
  4. Use a Phillips-head screwdriver #2 to remove both mounting screws by turning counterclockwise, placing the screws in your pocket or a container.
  5. Grasp the LED module housing and pull it forward approximately 1 inch until you can see the white wire connector attached to the back.
  6. Locate the wire connector—a white rectangular plug approximately 1 inch wide with 2 wires (typically red and white or black and white) leading into it.
  7. Press the connector’s release tab (a small rectangular protrusion on the top surface of the connector) while simultaneously pulling the connector apart with steady force to separate the two halves.
  8. Remove the old LED module completely from the housing cavity.
  9. Take your replacement LED module (part number W10515058 for fresh food sections, W10515057 for freezer sections) and align the wire connector with its mating connector in the housing.
  10. Push the connectors together until you hear and feel a distinct click, indicating the locking tab has engaged.
  11. Slide the LED module back into the mounting position, aligning the two screw holes with the threaded mounting points.
  12. Insert both Phillips-head screws and tighten clockwise using hand-tight pressure plus one-quarter turn.
  13. Snap the light cover back into place by aligning the clips and pushing upward until both ends click into their slots.

📋 Step 5: Verify proper operation

  1. Restore power to the refrigerator by flipping the dedicated 20-amp circuit breaker in your electrical panel to the ON position, or plug the power cord back into the wall outlet.
  2. Listen for the compressor to start within 30-60 seconds—you’ll hear a low humming sound coming from the lower rear of the unit.
  3. Open the refrigerator door and locate the interior light switch—a small white plastic button on the right side of the door frame, 4 inches down from the top—press it with your finger to verify the interior LED lights illuminate.
  4. Check the control panel display on the upper front interior wall—confirm it shows the default temperature settings of 37°F for the refrigerator and 0°F for the freezer within 15 seconds of power restoration.
  5. Press the refrigerator temperature down button (marked with a minus sign and snowflake icon) once, then press the up button once to verify the control panel responds—the display should change to 36°F, then back to 37°F.
  6. Open the freezer drawer by pulling the top handle—locate the ice maker in the upper left corner and observe the green status light, which should illuminate solid (not flashing) within 2 minutes.
  7. Place your hand over the air vents on the back wall of the refrigerator compartment, located 12 inches from the top—you should feel cool air flowing within 3-5 minutes.
  8. Check the water dispenser by pressing a glass against the dispenser paddle on the exterior door for 3 seconds—water should flow immediately if the water line was previously connected.
  9. Listen for the evaporator fan—a quieter, higher-pitched whirring sound from behind the back panel inside the refrigerator compartment—which should activate within 5 minutes of power restoration.
  10. Close both doors and allow the unit to run for 15 minutes, then recheck that temperatures on the display panel remain stable at your set points.
