I have a loose door handle on my Whirlpool refrigerator. The lower freezer handle is loose on the left side. The handle is horizontal. How do I tighten. Model gb2fhdxws04

It appears that you slid the handle to the right and remove. Then tighten the screw that fastens it to the door.

Upon closer examination I can't be sure. You may have to remove the inner liner.

If you remove the inner liner you will have to re-seal it with GE Clear Silicone caulk. If you don't you will have major problems from air leaks like you have never seen before. Here are some manuals: https://dl.dropbox.com/u/8010163/Whirlpool%20Refrigerators.zip
