Each time I tried to use my water dispenser, water would leak from the bottom of my Whirlpool refrigerator. I removed the rear cardboard panel and noticed that 2 of the water tubes were broken and were discolored brown.
It looks like the compressor got hot enough to reduce the flexibility of the 5/16 tubing and over time caused the water tubing to fracture and ultimately break in half. I went to the local appliance store and picked up 6 feet of 5/16 tubing (I had just enough) and 2 couplers. It's unfortunate that Whirlpool designed its refrigerators like this. The tubing should have been made out of a higher quality material to prevent this issue from happening.
