My Kenmore 9 upright freezer feels warm on the outside, what could be the cause. I have defrosted and cleaned it already and seems to work fine. however i am concerned with the outside temperature. Please help me!

The rust shouldn't make any difference.

When you plug it in, does the interior light turn on? If not, suspect the wall outlet - test it for power by plugging in something else. If the interior light turns on, listen very closely to the freezer. It should hum. If it doesn't, toy with the freezer control inside - it may just be turned off. Turn it to about midpoint and listen very closely to it again. If still no hum, wait a short while, then feel carefully on the outside of the cabinet - it may be running through a defrost cycle. The outside of the cabinet may get warm while that's happening, especially around the door gaskets. Wait a while (half an hour, an hour, for the defrost cycle to finish - the freezer should run then.

If it never hums, then the compressor isn't running, so adding freon won't make any difference. Instead, suspect the defrost timer - that's a little electronic circuit board inside.

If it HUMS but never gets COLD, then you potentially have a freon leakage problem. It's difficult at best, though, to refill a refrigerator or freezer - they don't usually have refill taps.

Oh, yes. If the internal light never comes on but you've proven that the wall outlet has power, it's entirely possible that the plug is bad and needs to be redone.

Without the model number I'm not sure how to answer your question. Does your model have fans that blow warm air on the outside bottom or a front kick plate? What is your model number? Kenmore has model numbers like this example=> 123.3214567 If the fan has a restriction that causes a lack of airflow it can cause the hot Freon liquid that normally flows around the Yoder Loop inside edges of the freezer door to prevent frost buildup to become very hot because the condenser fan is defective or coils are dirty with dust restricting airflow. If the outside is hot you may have a defective condenser fan motor. That will cause the freezer to ger hot. I am here should you want my assistance....Sea Breeze

Check the condenser fan (outside at the rear) and check the coil isn't baking hot. Electronics or board wouldn't cause your symptoms. Check the simple things first!

It could be that your defrost system is faulty. If the freezer does not defrost now and then it will fill up the cooling fins with ice and get warm. The leaking could also be an indication of two much ice. Did you unplug it when it stopped working and then plug it back in?

I unplug mine and let it take several days. You break a line or punch a hole in a line and the freezer will be ruined. Just let it thaw out on its own to prevent damage.

It is in a defrost cycle if you wait for around 30 min.
it should come back on

yes. This is the way freezers work. Every freezer will do this. If the freezer doesnt do this it generally does not work properly. So to answer your question... its nothing to worry about.

trojo50,
your defrost elements are not working or the water inlet for the evaporator tray is clogged. That alarm is to let you know something else has triggered it. This could be s imple DYI solution or require a service call. let me know if you are up for the DYI.

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

The thermostat should be a close circuit when requesting cold temps. or when asking the compressor to come on. The exterior surface on some freezers warm when asking for cold inside. Yours has a condenser coil on the back and that should warm when cooling. If compressor is runningit should be wrm if no freon has leaked from freezer somewhere.
The defrost timer should rotate clockwise during the day and give approx. 3 defrost daily or about every 8 hours. Until the thermostat is resolved and asks for a closed circuit the compressor will not come on. Unplug freezer from outlet,remove thermostat wires, then turn the thermostat to its coldest setting and check again. If no closed circuit the thermostat will need replaced first. Hope this has helped you, Sea Breeze
