replace hand screw
unfortunately my fridge stopped working. I purchased another but wanted to try and repair the old one. when ew one arrived, the old one was supposed to be put in garage but instead was hauled away. Had delivery return next day but they had as already removed and lost the handle screw for the bottom freezer and the screw that holds handle in place. ordered the handle screw and picked up the nut. very simple to install the screw and put handle back on.

Leak in water filter supply line
I found a crack in the pex line from the valve up the back of the refrigerator to the water filter. I could not find the correct 5/16" size line locally to replace it. A guy in plumbing at Home Depot said he always repaired them by cutting out the crack and finding a piece of clear vinyl line that would fit tightly over the cracked pex to splice in a fix with hose clamps. I did that and it was a really bad idea. The line was obviously fatigued and failing because it just cracked further up and leaked again. I then looked up and ordered the correct line (actually both the supply and return since they were available). Installing the new lines was a breeze. The pex connectors are simple to disconnect and reconnect. Wish I had done that to start with. I looked for a youtube video for the proper replacement steps but all I found was a video of a guy who cut out a crack and stuck a pex connector in to replace the cracked section. By doing that he pulled slack from the valve end of the line which didn't exist and cracked the line again. I don't know why anyone would mess with patching one of these lines. The correct parts are available, cut to the right length, and removing and replacing them at the valve and the filter is dead simple.
