Hello, and thank you for using this service. I'll be helping you with your problem today.
It actually sounds like you have 2 different problems. Although it may just be one problem. The one problem that you definitely have is that your drain line is clogged and needs to be cleaned out. This often times happens for no reason at all and is just random. You will need to remove everything out of your freezer including the entire freezer sliding bin and all the racks, shelf supports, and icemaker. Then remove the back panel inside the freezer. Use a hair dryer to thaw all the ice out and locate the drain hole. Pour hot water down the drain hole until it's draining properly again. Once it's draining properly blow compressed air down to make sure it's clear. If you don't have compressed air, use a turkey baster to make sure the drain line is clear and draining properly. Cut a solid copper piece of wire about 6 inches long. Wrap it around the defrost heater a couple times just above the drain hole and extend it 2 inches into the defrost drain hole. That will transfer heat into the drain hole when the defrost heater turns on and will prevent the defrost drain line from freezing over in the future.
Also, if you didn't want to use a copper wire, there is an actual kit made which you can wrap around the heater if you wanted to buy the actual kit to perform this task.CLICK HERE
Now if you wanted to avoid doing all of that, you can unplug the refrigerator for 24 hours and then pull the refrigerator forward and remove the lower back access panel behind the entire unit. Locate the drain hose coming from the drain hole inside the freezer and blow compressed air up and that will clean out the drain line.
Your other issue of the unit needing to be defrosted could be caused from the added moisture created from the freezer not draining properly. So you'll want to fix the drain issue first and if the cooling still acts up but the leaking has stopped occuring, then you'd need a new defrost control kit which was redesigned.
