Freezing food in refrigerator section

I have similar Kenmore. Ref part started freezing food, then a few days later I saw water on ref shelves. Long story short, removed ice maker, removed back panel of freezer (may have to defrost ice a bit to free it), and then saw ice buildup in drain tray and over drain tube. Removed back of refrig to see drip pan. Then in the freezer part, used hair drier and poured hot water on the ice to melt it. Soaked water run off with towel. Continued until water flowed down drain tube. Checked in the drain pan to see the water.

THEN from what I saw on another video, added an 18 gauge cooper wire apox 12″ long to the lower heating element. There are two elements, one on top of the cooling fans and one on the bottom. These heat up during the defrost cycle to melt ice. Water drips into the drain tray and down the drain tube. Careful when working around the fans, they bend easily and cut fingers even easier.

Looped one end of wire on the left side of the lower defrost element Then looped the other end on the right side of the lower element while shaping the cooper wire down to but not touching the drain tray (C shape). This should put heat right over the drain tray and tube to help melt any ice buildup.

ALSO from what I read about one of the causes of this ice build up in the freezer, warm moist air rises in the drip tube, meats the cold freezer air, and the moisture freezes up in the drain tube causing the ice dam. So I purchased two small elbow tubes and a worm clamp. Using pipe tape, connected the two elbows into a U shape and added them to the bottom of the drip tube. Use pipe tape and clamp to secure to the bottom of the tube. When water drips from the freezer, some of it stays in the U and prevents warm moist air from rising to the heater. Similar to the U shape in plumbing to keep sewer gases out of the house. QED so far.
