Hello, I have a water problem at the bottom of my fridge. I think that my defrost freezer drain is clogged. I know how to fix things, but I don't know how to remove the back panel in my freezer compartment so that I can fix the problem. There are no screws. Can you please send me the instructions to remove the back freezer panel. My serial number is:AF040073 and the fridge is a beaumark model 38371B. Thank you. I understand that I handle this at my own risk. I also want to mention that this fridge is only 4.5 years old and that I've never had a problem with a fridge this young. Usually after 20 plus years there may be a problem. Please help me because I'm tired of drying the bottom of the refrigerator every day. Thank you. Boris Wilhan
