Please provide me with detailed instructions on how to replace this part.
Answer Hello Ted,
You will need to pull the unit out from the wall and remove the galvanized cover from the top rear of the unit. Remove the two water lines. These will be John Guess fittings. To remove the water line from a John Guess fitting, push the water line into the fitting and push the ring around the water line toward the water head. While holding the ring in, tthe water line will slip out. You will now need to go inside the fresh food compartment and remove the filter and the single screw above where the filter mounts. Re-install in the reverse order. To re-install a water line into a John Guess fitting, push the water line in until it bottoms. When you feel it bottom, push hard and the water line will "pop" in another 1/4 inch or so. This has popped the line into the seal. To seat the seal pull on the water line only.
