Kenmore 72102100 the freezer drain hole is plugged which eventually causes the condensation to freeze resulting in ice build up around and under the aluminum sheet. Also,the appliance seems to run continuously.

you need to use a thin soft wire of some kind and clean out the drain plug holes, u can try using hot water over them but seems like the line may be plugged with rotten food etc.

Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick. Another trick one can use is to connect a copper tube wire with one end going into the drain hole then attach the other end to the heater wrap it around heater a few times. That will take care of the drain problem when it comes to ice build up but not food build up.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced. ( usually the line is under the freezer bottom plate covering. Towards the back of the unit) And there is another inside the fridge area also.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.

OTHER THINGS TO CHECK ARE THE DEFROST TERMINATOR AND THE HEATER ELEMENT FOR COBNTINUITY.
Unclogging Frost Free Refrigerator Condensate Drain How to Unclog Refrigerator Drain Line Refrigeration System Basics Chapter 1

There is a fan in the back of the freezer that runs when the compressor is running. It sounds like you have ice build up around the fan.
You could have one of these problems: (Sorted by most likely to least likely)
1) Auto Defrost timer, defrost bi-metal or defrost heater is defective - the unit will go into auto defrost about twice a day, if this fails you will have lots of ice built up around the cooling fins and sometimes on the fan. Pull the back off the inside of the freezer and check for ice build up around the cooling fins, there should be none or very little if its running normal.

2) Bad door gasket - if the freezer door is leaking warm moist air inside the freezer it could be condensing around the fan causing ice (you will also see ice build up on things inside your freezer too).

3) Plugged drain - the drain leads from the freezer down to the drain pain under the fridge. If this is plugged ice will build up on the bottom of the freezer and potentially around the fan.

Hi this problem could arise due to various reasons so lets find out what could it be the cause.

1)In the back of your freezer compartment is the drain hole. It's very common in GE for the drain to freeze up. With the drain hole plugged up, your freezer will continue to defrost the evaporator, but not the water in the drain hole. So the water builds and freezes, builds and freezes until it eventually overflows into the air diffuser for the fridge causing the leaky fridge problem."Heat Probe" that can be installed.This will prevent water from freezing up in the drain hole allowing it to drain as designed

2)Inspect the door seals and the sides of the refrigerator around the doors. If you see any beads of water or moisture, then the door seals may be failing to create an air tight seal which causes the cold air from the refrigerator to escape and form condensation around the doors. Sometimes you can solve this problem by applying a light film of gasket lubricant to the existing seals or just cleaning them of any debris with a warm soapy rag. If they still don't seal well after you apply lubricant, or clean them, you may need to replace the entire seal assembly.

3) If the water is coming from the freezer but you think that the defrost drain pipe is clear, then it may be coming from the ice maker. Check the ice maker for cracks in the unit's body or a misalignment of the water supply line. Make sure that the water supply spout in the freezer lines up with the ice maker's water supply cup.

4)Check the ice maker copper water supply line, your ice maker water filter, and the plastic ice maker water supply tube for any cracks, splits or connection leaks. If you find any leaks, remove the leaking part and obtain a replacement at the hardware store.

5)Your leaking refrigerator may just have a cracked or damaged drain pan. Your fridge regularly drains water into this pan to prevent water pooling in the fridge itself. Evaporation takes care of the rest. Look underneath your fridge where the drain pan sits and pull it out for inspection. If it has a crack or is otherwise damaged, contact the appropriate retailer about getting a replacement as soon as possible.

6)If your leaking refrigerator is draining inside as opposed to onto your floor, you're probably dealing with a clogged defrost drain. Your fridge is constantly producing condensation inside the freezer, and that condensation drips down the defrost drain into a drain pan underneath the unit. This defrost drain can become clogged with debris or, more often, it freezes shut. Look in your refrigerator manual to locate your defrost drain, and take the appropriate steps to unclog it (inundating your drain with warm water will often do the trick).

Note:Switch you Refrigerators for more than 8 hours and let the frost melt fully use hair dryer and now switch on and check you are getting leak.

Thank you for using fixya have a nice day:-)

The evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.

Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help. Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the back of the freezer. If this repeatedly happens with yours, you may can prevent it by taking a bare copper wire and wrap it around a fin near the heater and put the other end a few inches down the drain. The heat convection may prevent it from freezing.

your defrost drain on the freezer side is stopped up causing the drain to freeze over then eventually running out on the floor during the defrost cycle. Locate the drain at the back of the freezer and thaw it out using hot water. Using a screw driver or other object gently push down into the defrost hole and dislodge whatever is stuck there.

An air hose with good air pressure may also work well. When the drain line is clear you should be able to pour water through it freely.

I have an LG armoire style fridge/freezer and it had lots ice in the bottom and would eventually drip onto the floor. The problem was with the defrost controller. The moisture that enters the freezer when it is opened condenses and freezes on the freezer coil/fins. There is a heating element that sits under this coil which gets turned on by the defrost controller to melt the frost/ice. As the frost/ice melts it drips into a metal tray which channels the water to a drain hole to have it drop into the drip tray underneath the unit for it to evaporate. The problem is that the before the water has time to leave the freezer, it freezes thereby plugging up the drain hole and thus causing subsequent defrost cycles to have the water flow into the bottom of the freezer where it freezes. Eventually the bottom of the freezer fills up with enough ice for the melted water to flow onto the floor. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.

When I had the problem and started diagnosing it I opened up the freezer, pulled out the racks, draws, and eventually the door. Then I removed the ice maker and then a few screws and carefully removed the back white wall panel disconnecting the fan and any other electrical connections. Behind the panel you will see the cooling coil/fins, the heating element, the drip pan, and drain hole. Most likely you will see a sheet of ice everywhere. The best way to remove the ice is to boil a bunch of water in a tea kettle and slowly pour it on the ice to get it to melt so that you can start breaking out the pieces. Have a sponge and bucket ready to remove the water as the ice starts to melt. Eventually you should get all of the ice removed and get the drain hole unplugged. After all the ice is removed, you still need to fix the real problem by replacing the defrost controller, using the paper clip trick, or both.

just did as you said clean ice out around drain hole

the drain hole could have ben clogged with dirt and now with ice as the water did not drain as it went back to freezing mode. un plug the unit, let the ice thaw for a day, open the rear cover of the freezer and clean the bottom part of the evaporator. you can find the hole at the bottom part of the drain pan. i hope i was able to help.

I have a Kenmore Coldspot Model 70262990. When I get wet shelves (water, not just condensation), I was able to trace my source to the cold air vent from the freezer. In my case, the water melts from the evaporator and collects in the rear lower section of the freezer. It is "supposed" to go down the drain tube. However I had the drain hole freeze over. Then additional water from the defrost cycle would accumulate in the freezer floor (under the plastic floor) and eventually find its way down the cold air vent between the freezer and refrigerator section. You'll need to unplug the unit, take the plastic floor out of the freezer, remove the evaporator panel to access the defrost drain, melt the frozen water (hair drier works nice), and remove all the water (towel/sponge & bucket). Make sure the drain is not frozen and not blocked. Then put it back together and plug it in.

Does anyone know how to stop the drain tube from freezing over?

Good luck.

Yes that is a proplem...when ever that compressor is running that fan motor should be running too.. also you evapurator fan motor should be running also
