📋 What You’ll Need

  • Filter housing
  • O-rings

🔧 Step-by-Step Repair Instructions

🔧 Step 1: Inspect filter housing

  1. Open the refrigerator’s right-side fresh food door fully to access the upper right interior corner.
  2. Locate the water filter housing in the upper right corner of the fresh food compartment, approximately 2 inches from the top and 3 inches from the right wall.
  3. Identify the cylindrical filter cover cap, which is a white or light gray plastic piece approximately 2 inches in diameter with textured grip ridges on its surface.
  4. Look for the filter status indicator light on the control panel at the top of the fresh food compartment—it will be blue (good), yellow (replace soon), or red (replace now).
  5. Examine the filter housing exterior for visible cracks, specifically checking the seam where the cap meets the housing body and the four mounting tabs at 12, 3, 6, and 9 o’clock positions.
  6. Check for water stains, mineral deposits, or moisture on the housing, the ceiling panel around it, and the wall behind it within a 6-inch radius.
  7. Run your finger along the bottom edge of the housing where it meets the refrigerator wall to detect any dampness or water droplets.
  8. Inspect the floor of the fresh food compartment directly below the filter housing for standing water or water marks.
  9. Look for white calcium buildup or green/black mold around the filter cap threads and housing opening.
  10. Check that the housing sits flush against the refrigerator wall with no gaps exceeding 1/8 inch between the mounting flange and wall surface.
  11. Verify the filter cap rotates freely by attempting to turn it counterclockwise approximately 1/4 turn—do not remove it yet, just test for binding or resistance.
  12. Note any unusual odors emanating from the filter area, which may indicate bacterial growth or trapped water.

🛠️ Step 2: Check O-ring condition

  1. Locate the water supply line connection point at the bottom rear of the refrigerator, approximately 4 inches up from the floor and 8 inches from the right edge when facing the back.
  2. Trace the water line to the filter housing mounted on the upper right interior wall of the fresh food compartment, approximately 2 inches from the ceiling and 3 inches from the right side wall.
  3. Turn the water filter housing counterclockwise one-quarter turn (90 degrees) and pull straight down to remove it from the housing bracket.
  4. Examine the black rubber O-ring (part number W10819506) seated in the circular groove at the top of the filter housing where it connects to the manifold.
  5. Run your finger around the entire circumference of the O-ring, feeling for cracks, splits, or flat spots – a good O-ring will feel uniformly round and elastic.
  6. Look for white calcium deposits, green discoloration, or hardened sections on the O-ring surface – these indicate deterioration.
  7. Press the O-ring gently with your thumbnail – it should indent approximately 1-2mm and spring back immediately; if it stays compressed or feels brittle, replacement is needed.
  8. Check the manifold connection point inside the housing bracket where the O-ring seals – look for water stains, mineral buildup, or corrosion on the gray plastic surface.
  9. Wipe the manifold seal surface with a dry cloth and inspect for scratches or gouges deeper than 0.5mm that could prevent proper sealing.
  10. If the O-ring shows any cracking, flattening, or hardening, order replacement O-ring kit (part number W10819506) which includes the O-ring and lubricant.
  11. Verify successful O-ring condition by confirming it is black (not brown or gray), uniformly round, and springs back when compressed – this indicates the seal is intact and ready for reinstallation.

⚙️ Step 3: Verify proper filter installation

  1. Open the refrigerator’s right-hand door completely to access the upper right interior corner where the filter housing is located.
  2. Look at the filter cap, which is a round, white plastic piece approximately 3 inches in diameter positioned in the upper right corner of the fresh food compartment, about 2 inches from the top and 3 inches from the right wall.
  3. Check that the filter cap sits flush against the housing with no gaps visible between the cap edge and the housing surface—any gap larger than 1/16 inch indicates improper seating.
  4. Grasp the filter cap with your right hand and attempt to rotate it counterclockwise—a properly installed filter will not turn at all, while an improperly seated filter will rotate freely.
  5. Examine the status indicator light on the filter cap: you should see a green LED lit, indicating proper installation and filter life remaining (red means replace filter, no light means improper electrical connection).
  6. Press firmly on the center of the filter cap with your palm using approximately 5 pounds of pressure—the cap should not move inward more than 1/8 inch.
  7. Run your finger around the entire circumference of the filter cap edge checking for uniformity—the cap should maintain the same distance from the housing wall all the way around, approximately 1/4 inch.
  8. Pull outward on the filter cap using moderate force (about 10 pounds)—the filter should remain firmly in place and not budge.
  9. Locate the small arrow molded into the filter cap surface and verify it points toward the “LOCK” position marked on the housing (pointing toward the refrigerator’s left side when viewing from the front).
  10. Dispense 2 cups of water from the door dispenser into a clear glass to verify water flows freely without sputtering or air pockets, which would indicate incomplete filter seating.

🔩 Step 4: Replace housing or O-rings

  1. Locate the water filter housing assembly, which is a cylindrical white plastic unit positioned in the upper right interior corner of the refrigerator compartment, approximately 2 inches from the top and 4 inches from the right wall.
  2. Identify the filter housing cap (the round white piece you previously removed) and flip it over to expose the black rubber O-ring seated in a groove around the circumference, approximately 0.5 inches from the outer edge.
  3. Insert a flathead screwdriver (4mm width) under one section of the O-ring and pry upward to lift it out of its groove. Work around the circumference until the O-ring releases completely.
  4. Clean the O-ring groove using a lint-free cloth dampened with warm water, removing any visible mineral deposits, sediment, or dried residue. The groove should appear uniformly light gray when clean.
  5. Take the new O-ring (part number W10295370A, typically included with replacement filters) and examine it for any manufacturing defects—the ring should be uniformly black with no cracks, thin spots, or irregularities.
  6. Apply a thin coating of food-grade silicone grease along the entire O-ring surface using your fingertip—you need approximately a pea-sized amount for complete coverage.
  7. Position the O-ring at the 12 o’clock position on the housing cap groove and press it into place with your thumbs, working clockwise around the circumference until fully seated. The O-ring should sit flush within the groove with no twisted sections or protruding areas.
  8. Inspect the housing base (the white cylindrical piece still mounted in the refrigerator) for cracks around the threaded area or the two mounting tabs located at 3 o’clock and 9 o’clock positions. If cracks exceed 0.25 inches, replace the entire housing base (part number W10413463).
  9. Verify the O-ring remains properly seated by running your finger completely around the groove—you should feel continuous, even contact with no gaps.

📋 Step 5: Test for leaks

  1. Turn the water supply valve clockwise until fully closed, located on the wall or floor behind the refrigerator, typically 12-18 inches from the left side when viewing from behind.
  2. Pull the refrigerator forward 24-30 inches from the wall to access the water line connection point at the lower back panel, approximately 8 inches from the bottom and 6 inches from the left edge.
  3. Place a dry bath towel or absorbent cloth directly under the water inlet valve where the supply line connects to verify any leakage during testing.
  4. Turn the water supply valve counterclockwise 2 complete rotations to restore water flow.
  5. Listen for water flowing through the line for 10-15 seconds, which sounds like a soft hissing or trickling noise.
  6. Inspect the compression fitting connection where the supply line meets the inlet valve using a flashlight, looking for water droplets, moisture, or wet spots on the metal threads and nut.
  7. Run your dry finger along the connection point and examine your fingertip under light—any moisture indicates a leak requiring the fitting to be tightened an additional 1/4 turn clockwise using a 1/2-inch adjustable wrench.
  8. Check the towel beneath the connection after 3 minutes for any water drops or dampness.
  9. Open the left refrigerator door and press the water dispenser paddle for 10 seconds to fill a clear glass with 6-8 ounces of water, verifying water flows steadily without sputtering.
  10. Return to the back of the refrigerator and re-inspect the connection point and towel for any new moisture or drips that appeared during dispenser operation.
  11. Wipe the connection area completely dry with a paper towel if no leaks are present—the fitting should remain dry, indicating a successful seal.
