Kenmore 16.7 cu upright frost free freezer
Since everything seems to work properly it may just be your temperature sensor, etc. has always been out of calibration. The t-stats are only about $23 bucks and very simple to replace. Pull the temp knob off and there you'll see the screws. I'd start by replacing this first then seeing if the temps are more controllable. Usually a 3-5 setting is good so being way low on the dial seems unusual. The drain hole copper I use is 1/4" copper tubing that I cut to about 6" long, hammer a few inches flat then use pliers to round a hook shape into the flat end. Test hang it on the heating element with the other end of the copper about 1" into the drain hole (cut as needed). That ensures the water will drain and not refreeze before if flows out. Also check that the hole drains fast, use hot tap water and pour a 1/2 cup in real fast to make sure you see it flow out fast. If it's slow the drain tube may be clogged (I've found green peas are perfect to plug a hole). www.partselect.com
