🔧 Step-by-Step Repair Instructions

🔧 Step 1: Test dispenser switch continuity

  1. Unplug the refrigerator from the wall outlet or flip the dedicated circuit breaker to the OFF position.
  2. Open the left refrigerator door fully to access the dispenser control panel.
  3. Locate the dispenser control panel on the exterior of the left door, centered horizontally approximately 58 inches from the floor.
  4. Remove the trim panel by inserting a flathead screwdriver (5/16-inch wide blade) into the slot at the top edge of the panel, 2 inches from the right side.
  5. Pry the trim panel away from the door, releasing 6 plastic clips that secure it—3 along the top edge and 3 along the bottom edge.
  6. Set the trim panel aside to reveal the dispenser switch assembly mounted to the back of the control panel.
  7. Identify the dispenser switches—you’ll see 3 rectangular switches: water (left position), crushed ice (center position), and cubed ice (right position). Each switch has 2 metal terminals on the back.
  8. Press the water paddle located at the bottom of the dispenser opening. You’ll feel it depress approximately 3/8 inch and hear a click from the water switch.
  9. Set your digital multimeter to the continuity setting (Ω symbol) or resistance setting on the lowest scale (200 ohms).
  10. Touch one multimeter probe to each of the 2 terminals on the water switch while keeping the paddle depressed. The meter should read 0-2 ohms or beep, indicating continuity.
  11. Release the paddle and test again. The meter should read OL (open line) or infinity, indicating no continuity.
  12. Repeat steps 8-11 for the crushed ice paddle (middle) and cubed ice paddle (right).
  13. If any switch fails to show continuity when pressed or shows continuity when released, the switch assembly (part number W10874849) requires replacement.

đŸ› ïž Step 2: Check water inlet valve operation

  1. Locate the water inlet valve at the back lower left corner of the refrigerator, approximately 4 inches from the bottom and 8 inches from the left side edge.
  2. Unplug the refrigerator from the wall outlet to cut power completely.
  3. Turn off the water supply line by rotating the shut-off valve clockwise until it stops (typically requires 4-6 full turns).
  4. Pull the refrigerator forward approximately 2 feet to access the rear panel.
  5. Use a 1/4-inch nut driver to remove the 6 screws securing the lower rear access panel (3 screws along the top edge, 3 along the bottom).
  6. Set the panel aside and identify the water inlet valve—a white or gray plastic component with two solenoid coils on top, approximately 3 inches wide by 4 turn inches tall.
  7. Disconnect the wire harness from each solenoid coil by pressing the locking tab and pulling straight out (you’ll find one connector on each coil).
  8. Set your multimeter to ohms (Ω) setting at 200 ohms range.
  9. Touch the multimeter probes to the two metal terminals on the first solenoid coil. The reading should show between 200-500 ohms. Record this value.
  10. Repeat the ohms test on the second solenoid coil. Both coils must read within the 200-500 ohm range.
  11. If either coil reads infinite (OL on digital meters) or zero ohms, the valve has failed and requires replacement with part number W10408179.
  12. Visually inspect the inlet and outlet ports on the valve for white calcium deposits, cracks, or debris buildup.
  13. If the valve passes electrical testing (200-500 ohms on both coils) and shows no physical damage, reconnect both wire harnesses—they will click when properly seated.
  14. The valve has passed this operational check if both solenoids measure correctly and no physical damage exists.

⚙ Step 3: Inspect control board connections

  1. Locate the main control board mounted on the right-side wall of the refrigerator compartment, approximately 8 inches down from the ceiling and 2 inches from the right wall behind a white plastic cover.
  2. Remove the control board cover by pressing the two retaining clips located at the top corners and pulling the cover forward, then lifting it up and away.
  3. Identify the main control board, which is a green rectangular circuit board measuring approximately 6 inches by 4 inches with multiple wire harness connectors attached.
  4. Count all wire harness connectors on the control board—there should be 6 total: three white connectors on the left side, two black connectors on the right side, and one gray connector at the bottom.
  5. Inspect each connector starting from the left side, looking for these specific issues:
  6. Grasp the first white connector on the left by its body (not the wires) and gently wiggle it side-to-side to check for looseness—properly seated connectors should have zero movement.
  7. Press firmly on each connector until you feel or hear a click, confirming full engagement with the board—the connector should sit flush against the board surface with no gap.
  8. Examine all visible wire insulation within 3 inches of each connector for cracks, brittleness, or exposed copper strands.
  9. Check the control board itself for burn marks, bulging capacitors (cylindrical components that appear swollen at the top), or cracked solder joints around the connector pins visible as broken silver rings.
  10. Note any damaged connectors or wires—these will require replacement with connector part number W10759846 for white connectors or W10759847 for black connectors.

đŸ”© Step 4: Test dispenser actuator

  1. Locate the dispenser actuator assembly on the left-side interior door, positioned 3 inches below the ice chute opening and centered horizontally within the dispenser housing.
  2. Set your multimeter to continuity mode (Ω symbol with sound wave icon).
  3. Identify the actuator’s white plastic paddle that extends through the dispenser front panel – this is the piece you press to dispense water or ice.
  4. Press firmly on the water dispenser paddle with your finger, applying approximately 2-3 pounds of pressure until you feel it depress fully (about 1/4 inch travel distance).
  5. While holding the paddle depressed, touch one multimeter probe to the left metal terminal on the actuator switch body and the other probe to the right terminal – you should hear a continuous beep indicating closed circuit (0-2 ohms resistance).
  6. Release the paddle completely and repeat the meter test on the same terminals – the beeping should stop, indicating an open circuit (infinite resistance reading as “OL” on display).
  7. Repeat steps 4-6 on the ice dispenser paddle (located adjacent to the water paddle), testing the second set of terminals positioned 1 inch above the water actuator terminals.
  8. Press each paddle 10 times rapidly, listening for a distinct click sound with each press and release – inconsistent clicking indicates internal spring failure.
  9. Visually inspect both actuator paddles for cracks in the white plastic housing or bent metal contact arms visible through the small rectangular opening behind each paddle.
  10. If either actuator fails the continuity test (no beep when pressed, or continuous beep when released) or shows physical damage, the actuator assembly (part number W10823377) requires replacement before proceeding to electrical testing.
  11. If both actuators pass all tests, move the multimeter aside and proceed to the next step.

📋 Step 5: Replace faulty components

  1. Locate the defrost heater mounted beneath the evaporator coils in the freezer compartment, running horizontally across the bottom of the coil assembly.
  2. Disconnect the two wire connectors (white spade terminals) on the left and right ends of the heater by gripping the plastic connector housings and pulling straight off.
  3. Remove the single metal mounting clip at the center of the heater by sliding it toward the right edge approximately 1 inch until it releases from the bracket.
  4. Lift the old heater assembly straight up and away from the evaporator coils.
  5. Position the new defrost heater (part number W10918566) into the same horizontal channel beneath the coils.
  6. Reinstall the center mounting clip by sliding it from right to left until it snaps into the bracket opening—you’ll hear an audible click.
  7. Push the white spade connectors onto both terminals until they seat completely flush against the terminal base.
  8. Locate the thermistor sensor clipped to the evaporator coils on the right side, approximately 8 inches from the top of the coil assembly.
  9. Disconnect the 2-wire connector (blue and white wires) located 3 inches to the right of the sensor by pressing the locking tab down with your thumb and pulling the connector apart.
  10. Squeeze the plastic retaining clip securing the thermistor to the coil tube and slide the sensor upward to remove.
  11. Slide the new thermistor (part number W10316760) onto the same coil tube location.
  12. Press the retaining clip firmly until it snaps onto the tube—the sensor should not move when you attempt to slide it.
  13. Reconnect the 2-wire connector by aligning the plastic tabs and pushing together until you hear a distinct click.
