When going on vacation, I do the following:

1.  Turn Ice Maker Off
2.  Turn House Water Off
3.  Open Kitchen Faucet (to drain some of the water from the lines,  still have a small stream before I close the faucet)
4.  Close the Kitchen Faucet

When I get home,  I noticed that the small tray that feeds the ice maker has frozen over.  I’m guessing that some water dripped into the tray while I was gone.  If I turn the ice maker back on,  I get a lot of ice all over the freezer.

I believe there is a shut off valve for the refrigerator water under the kitchen sink.  Should I be closing that?

I have an appliance repair guy coming out to replace the water valve in the refrigerator.

Am I doing something wrong in how I am shutting off the water?
