Defrost Drain Pan | 'link'

Most pans slide out or are held by two clips. Warning: It is likely full of gross water. Slide it out slowly and pour the liquid into a bucket or sink.

Water doesn’t magically appear in the pan; it travels via a small tube from the freezer down to the pan. If food debris or ice blocks that tube, the water backs up and freezes inside the freezer floor (causing that dreaded ice dam) or leaks out the bottom of the fridge door. defrost drain pan
