Yes, I believe it is 1/4" plastic tubing.
Okay. Thanks Barry
Chris usually what causes this problem is heat from the compressor. What you will want to do is cut a section out that is near the compressor then add a piece in with either of the 2 parts pictured below. Both are for plastic water line. Cut a piece out and take it with you along with a picture of the 2 fittings below to either Lowe's or Home Depot. One or the other should have the line and one of the styles of fittings. That will take care of it and as long as the ice maker is off and no one uses the dispenser it will not leak.If you found my answer satisfactory please login if you are not already logged in and please leave an ok or better rating so that I am compensated.
