Mystery Leak & Inoperative Fridge - related?

I had winterized the icemaker last fall leaving the supply hose just loosely attached on my 09 Journey. I had turned off the supply at the needle valve below the sink and made sure it was tightly closed. The valve failed and produced a continual drip in the outside compartment that ran down and into the carpet under the cabinets on both sides of the fridge. Check your needle valve as they appear to fail with over-tightening and insure water isn't getting past it.
