Removed the old line and replaced with the new. This is the sixth time I've replaced the line. Yes you read that right, the sixth time. Lines fail about every 6-8 months so I can change one out now in about 10-15 minutes. Bought the refrigerator in Feb '09 and the line first failed in March 2012. Since then I've had failures in as little as 4 months to as much as 9 months. Frustrating to say the least, but I'm a whiz at changing out the line :-)
