I have Kenmore upright that continues to run and has a layer of ice in bottom. The unit is self defrosting.
I adjusted the temp control to warmer setting, but it will not shut off automatically,
Thanks for help.

Re: Continues to run
It seems your temp. control board or thermistor is not reading the temps and just keeps on running and running. Can you lower it to the lowest setting and (with a thermometer) see if the temps actually get warmer inside (will take a day or two to warm up).
As for the ice on the bottom if the drain for the defrost cycle is plugged you may be getting water inside which then re-freezes. Let us know what you find and we can go from there.

If refrigerant charge is ok, make sure that the evaporator coil is not covered with ice. The latter serves as an insulator and will keep unit from achieving designed low temps. Remove ice by defrosting unit manually and then restarting unit. If ice continues to build up at alarming rate check for the tightness of door gaskets. If lots of moisture gets into unit, it will collect and freeze on coil. Also check to see that the defrost timer is not going on excessively. Those defrost cycles can raise internal temps by as much as 25 degrees; if the cycles come on prematurely and/or very often internal temps will be high.
Hi most deep freezers operate at 0 dergrees. your model may have 2 temp zones. 0 or 20 deg.I'm gessind that your sensor is going off when the defroster is on to melt ice (defrosting). Lower the setting. monitor and repeat as needed. if it continues you may need to replace the unit or ad freon. If the unit is over 13 years ge a new one.
Do you have the complete model number from the tag on the freezer, it should be either on the bottom rail visible with the door open or on the side wall near the front. I am trying to look this up to see if it is an automatic defrost model, if so you may need to do more than just unthaw and adjust
After you taken the back panel off and see a lot of ice forming on the coil before you use your hairdryer you should locate the timer and turn the center of the timer manually into defrost cycle. If you can see or hear the ice melting then your problem is the timer defective. Change the timer and that is all. But if it doesn't do anything then you will need a little bit more on electrical knowledge to deal with the rest on defrost temperature control and the element itself. Hope this help, God Bless.
One reason for the fan running is that it is trying to distribute the air in the compartment. Look at the very rear of the freezer on the bottom and see if the little vents, which allow water to disperse, are not filled with frozen ice. If so, turn off the fridge (unplug it) and use a hair dryer to melt that ice until it is all gone. That will probably fill the condensation pan under the unit and you'll need to empty it.
not necessarily, is it maintaining temp? all food staying frozen? especially ice creams if stored in there. most newer freezers displace the heat generated while cooling the food through copper lines running through sides of unit, helps to cut down on air temp differences between the inside (0 degrees) and outside temp to prevent moisture and possible condensation causing premature rusting of unit
Make sure everything is working, I.E. compressor, fans. Now I need to know if the freezer shuts off at 14 degrees, or does it continue to run without making temp. If it shuts off, then the first place to look is the thermostat. It may be out of calibration. If it continues to run, then the solution may be as simple as cleaning the condenser coil. or the defrost has malfunctioned somehow. Defrost probleams will cause excess ice on the inside coil. You may need to remove the panels to see how much ice is on it. It sounds like the compressor is good, as it is pretty cold. Just not cold enough. A deep freeze should be at least 0.
You should check the drain hose inside underneath the freezer.This is done at the back down below. Mine was looped too high and water could not get out. I took the loop off that was holding the hose and now water can drain away without freezing. You can pour warm water down the drain hole to melt the ice in the tube if you remove the grate covering it inside the freezer. I have read that several Kenmore upright freezer owners have the same problem. I was astonished that this was the problem and I had put up with it for too long, defrosting the freezer every 2-3 months!.Give it a try!
I looked at the BACK at the bottom underneath of my Sears Kenmore frost free upright freezer and what was causing the ice buildup was very simple. At the factory, the assembler looped the little hose too high and when the water went into the hose it could not get out due to being too high in one spot! An ice dam will form, blocking ALL water coming through and freezing up any more water coming down giving you a HUGE wad of ice that is scary!!! I just removed the screw holding the loop that holds the hose and put a bit of warm water down the little hole on the INSIDE (Behind the grate) to melt the remaining ice in the tube.You need to take out 4 screws and remove the grate to see this. I could not believe that this was the problem! I haven't had any ice build up since.Now don't tear your freezer apart before you try this trying to fix the compressor, thermostat etc. It may be the only thing wrong with it!
