Kenmore Upright 13 cu.ft freezer- uneven freezing

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!

get a new one cheap ***

check door seals, also check vent direction, a dial or lever in fridge, it adjust how much air goes to fridge and freezer

Is the compressor running the whole time? If so may have a problem with a refridgerant leak....check the compressor in the rear of unit, feel if its hot....may be as simple as a relay.

It had to run longer than normal to cool down the freezer again. The heat from the compressor running is what you feel.

I would not worry about it unless it is still hot after 24 hours. Then there is another problem.

It sounds like the unit is low on freon or the compressor is going bad. You have several other components that could be affecting this as well. Make sure the coils are free from dust and clean underneath. This is a bit premature for you to have problems now, especially since it is a Sears product.

Control is bad and needs to be replaced. I cannot see your repyl due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

The most likely answer is a slow freon leak assuming it was getting to the right temperature before you went on vacation.

when you plug it in do you ear a fan running if not plug the freezer on.and at the bottom of the freezer gently hit were you have a grill sometime the fan motor gonna start running and circulate the cool air if it work keep and eye on it for a few days take care cheers

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
