Ice maker door not closing, and a water line issue

I have a ~9 year old Kenmore Elite side by side refrigerator/freezer. Over the last few months, I've noticed the flap that opens to allow ice to be dispensed does not close completely. When not dispensing ice, the flap sits about 1/2" open. If I push the flap closed, it's as if there's not enough tension to hold it closed. I've read in a few threads here that the problem could be the spring that holds the door closed, or the solenoid that closes the door, but didn't find the part numbers for my specific model. Also, is there a way to trouble shoot between those potential issues?


I've also had issues with a white cloudy substance coming out of the water dispenser since I moved into my house about a year and a half ago. This was an issue with the ice maker initially, but was solved by dumping out several bins full of ice. I've tried running water through the water dispenser, but it hasn't helped. Is there a way to clean the water line/dispenser, or should the water line just be replaced?

thanks!
