To cold Displays LL instead of temperature

Found this

The temperature is factory preset to provide satisfactory food storage temperatures. However, the temperature control is adjustable to provide a range of temperatures for your personal satisfaction. If a colder temperature is desired, turn the temperature control knob toward MAX and allow several hours for temperatures to stabilize between adjustments.

In my experience, the temperature adjustment knob is behind the grill on the side. They put it hidden there because you hardly ever need to touch it. The model number isn't quite right for a Kenmore. It should be 3+5 numbers 123.12345 like this one 253.12502

pull the panels inside and check the fan usually in a fridge freezer the fan cacks out or is full of ice clean it out and clean the overflow tube if fridge is cold enough then it is the freezer fan

Hello Ron Thacker - Often when the temperature is too cold, it is because the temperature control is set too cold/high. Turn the control to a warmer setting and allow several hours for the temperature to stabilize. If the unit does not stabilize within 24 hours, then it could possibly have a faulty thermostat or temperature control. I would personally reach out to an experienced tech that will be able to identify the precise reason.

Does the compressor kick on?

When it comes to freezer units, there is not much one can do on their own. You can try to move it around and clean any debris from underneath and behind it. You can see if the internal temperature matches what you have it set on, and then you'll need to contact a professional to diagnose the actual sealed system of the unit.

Hello,

The temperature controls are located at the top front of the refrigerator or freezer compartments.
The recommended setting should be correct for normal household refrigerator use. The controls are correctly set when milk or juice is as cold as you like and when ice cream is firm.
Wait 24 hours for your refrigerator to completely cool before adding food. If you add food before the refrigerator has completely cooled, your food may spoil.
NOTE: Adjusting the refrigerator and freezer temperature controls to a colder-than-recommended setting will not cool the compartments any faster.
If the temperature is too warm or too cold in the refrigerator or freezer, first check the air vents to be sure they are not blocked before adjusting the controls.
To turn Off/On:
Style 1 Press the freezer down arrow touch pad until a dash (-) appears in both the refrigerator and freezer displays. Neither compartment will cool.
Style 2 Turn the freezer control to the word Off. Neither compartment will cool when the freezer is set to Off.

Energy Saver option (on some models)
The Energy Saver option turns off the heater which helps to reduce moisture on the door hinge seal. The refrigerator uses more energy when Energy Saver is off.
Press the control to On to save energy when the environment is less humid.
Press the control to Off when the environment is warm and more humid, or if you notice moisture on the door hinge seal.

Adjusting controls
If you need to adjust the temperature in either the refrigerator or freezer compartment.
NOTES:
For Style 1 control, press the up and down arrow touch pads; for Style 2 controls, turn the dial to adjust the temperature.
Except when starting the refrigerator, do not adjust either control more than one setting at a time.
Wait 24 hours between adjustments for the temperature to stabilize.

Hope this guideline will helpout.....

the thermostat has cut it out outside temperature being cold

Hello there:
first make sure that the back of the unit is clear of any dirt or obstructions
also make sure that the food is not stacked up so high that the air cannot circulate also you may want to check the temperature setting if the unit does not respond to a lower setting your refrigerant level may be low or than you will have to have the temperature controle thermistor serviced or replaced

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

simple stuff, you have a compressor a stat and power. check the receptacle to be sure you have 120 volts . then check the compressor with stat at max cold setting to see if you have 120 volts at compressor. if you do then compresssor is bad =new compressor or new unit. if no power to compressor then stat is bad= new stat. i always recomend new unit cause new stat or compressor wont fix a freon leak.... i have replaced a few compressors that died soon after due to a freon leak. good luck...
