Our Whirlpool side-by-side refrigerator is about 8 years old. I just noticed that there are a number of small cracks in the plastic lining in the interior. They're about 1-2" in length, jagged, and there are probably 10 from top to bottom. All are located on the interior rear plastic panel, none on the sides. All are in the fridge, none that I can see in the freezer (freezer is lined with a different material). I thoroughly cleaned this refrigerator about 2 months ago and there were no cracks. I did recently move it when I painted the kitchen, however, but didn't notice anything after that either. I only pulled it out of its corner, and it moved very smoothly. No "traumatic" movement or jolts.
I tried to find some information via Google, but came up empty. Are these cracks essentially just a cosmetic issue (there are no gaps, per se, just "lines"), or is this something that'll eventually get out of hand? Is there a material that can be used to fill the cracks or is it simply time to bite the bullet and get a new fridge? Eight years isn't exactly my idea of a long life, but of course it's not exactly "spring chicken" material either. ;) The only other potential "issue" that I've had, prior to moving the fridge, was hearing an occasional trickling noise. The overflow pan is fairly dry though. So I'd hate to replace this thing if it's not absolutely necessary.
Any advice would be greatly appreciated! KB
