I have a frigidaire (Model FRT18IL6DS4) that was causing me problems (frozen ice maker tube) so I started prodding around and found out that the tube coming from my water supply was leaking at the copper coupling (not sure if that is what it is called). So I went out and purchased a new one and replace it and now it is leaking even more whenever the water is turned on. What do I do to stop the leaking? I took off the water inlet (not sure if thats what it is called, it is blue and has a power chord attached) and warmed it in case it was also frozen. help!
