Display reads off and it will not re adjust to anything. I have unlocked display but nothing changes the setting.

close door ===now just let it run normal dont adjust or do anything --probably did nothing

Press and hold the Control Lock key for three seconds
to activate or deactivate the function. The Control Lock
feature prevents the user from changing the temperature
and freeze settings. At the first press of any key, the
key press click tone will be heard and the display will
show "LO", but no other change will take place. Holding
the Control Lock key for three seconds will activate or
deactivate the Control Lock feature. After three seconds,
the accept tone sounds and the Control Lock LED (if so
equipped) is activated. In lockout mode, when any key
is pressed, the invalid key tone will be heard and "LO"
will be displayed for 1 second. When the lockout is
deactivated, the Control Lock LED is turned off and the
display shows "UL"

if this does not work unplug the freezer for 30seconds then plug it in. if all of the above fails replace the control.

Hello Michael - Sounds like the temperature control was accidently turned OFF. When this occurs the temperature control turns off the compressor, but does not disconnect the power to the light bulb or other electronics. Let's try activating the freezer by pressing the UP arrow until display shows "4" or desired setting. Allow 24 hours for temperature to stabilize. For future reference you can lock the control to keep from accidently changing the temperature setting. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

Hello - Typically "OF" indicates that the freezer is turn off. To activate freezer, press UP three times until display shows "1" then press UP to desired setting. If it will not allow you to change setting and freezer continues to be off, try resetting the freezer by unplugging it or flipping the breaker off. Wait approximately ten minutes and turn it on. If "OF" continues to display, the unit could possibly have a communication problem with the electronic control assembly. Contact a professional to move forward accurately.

Try checking the Temperature Control:Testing Temperature Control
Test the control for continuity using a multi tester. Set the multi tester to the ohms setting X1. Place a probe on each terminal. Turn the control to warmest setting or off. The multi tester should display a reading of infinity. If the control does not have an off position, the reading should be near the infinity end of the scale. Now change the control to the coldest setting and retest. The display should read zero ohms. If the control does not pass both of these tests, the switch should be replaced.

bad display unplug for a few minutes try again if nothing happens change the display membrane

There is a lock on the display. Try pressing standby button for 10 secs

The settings are "relative". Someone with this fridge in Montana may need to run the same fridge with different settings than someone in Texas to get the same temperatures.

Many manufacturers recommend that the fresh food compartment should be 34 degrees F, and the freezer -10 to 0 degrees F. To set this properly, place a thermometer in the freezer (that can display temperatures as low as the desired temperature). Adjust the thermometer for the correct freezer temperature before going on to the fridge. A fully stocked freezer could take 12 hours or more for temperatures to stabilize after making changes to the thermostat. Once the -10 to 0 degree temperature has been achieved, set the fresh food compartment temperature.

Place a thermometer (that can display below freezing) in a 6 (or so) oz flexible plastic cup of water and place on a shelf in the fridge. A glass of water could break if the temperature gets below 32 degrees if the water turns to ice. The water acts as a buffer to rapidly changing temperatures when the door is opened to read the thermometer. If the fridge is "full", allow 24 hours for the temperature to stabilize before making changes.

If the fridge and freezer are empty, changes may be seen in just a few hours or less. Otherwise, wait the 12 / 24 hours for the freezer / fridge compartments.

I hope this helps and good luck!

1. The first thing you must know is that your refrigerator should be set at 37-38 degrees. Anything at 40 or higher and you are risking food born illness (food poisoning) or spoiling your food. Place your magnetic thermometer in the refrigerator.

2. Set your dial on your refrigerator to the second lowest setting. (If your refrigerator is already equipped with a digital thermostat, simply set it for 37 or 38 degrees and do not move on to the next step)

3. After 2 hours, check your thermometer reading. If your reading is 38 degrees, there is no need to go higher and you are ready to put your groceries in. Be sure not to open and close your refrigerator during these two hours or your temperature reading will be incorrect.

4. If your reading is higher than 38 degrees, move your dial up to the next coldest setting and repeat the steps every two hours until you reach the correct temperature for your refrigerator.

5. Once you have reached the correct refrigeration temperature for your refrigerator, place the magnetic thermometer in the refrigerator permanently and watch for changes.

Typically, your refrigerator temperature will need to be adjusted with the seasons, a higher setting in the summer and a lower setting in the winter.
