Customer Questions and Answers for Refrigerator Defrost Timer by Whirlpool

Jim, Good guess but probably wrong. You most likely have a clogged or frozen defrost drain tube W10619951 When the refrigerator defrosts the water cant drain and seeps out under the evaporator cover and onto the freezer floor. You'll need to remove the back wall, and de ice the drain pan and tube and check for a clog in the tube itself.
