My fridge keeps beeping even though the door is shut. The fridge temperature indicator keeps going up and then down. Can you please tell me what's wrong?

If the reset procedures don't stop the beeping and you are out of warranty, here is an easy fix:
1- (You can unplug the fridge just to be cautious, but not necessary.) Remove the control panel from the front of the fridge. Mine pulls straight out without removing any screws.
2- On the back of the control panel is a black, round device - the only thing that pokes through the back of the panel. This device is small, maybe 1/2" in diameter and the same deep. (if it won't pop off easily, remove the 4 screws to remove the back cover for easier access.)
3- You will see a thin round disk inside. This is the speaker. Remove this disk, press the black speaker cover back on and press the control panel back into the front of the fridge.

All the controls will continue to work as before, but NO BEEPS!
Yea!

Is the beeping a door or temp alarm? You can press power cool and power freeze buttons at the same time and you should get a single LED indication and then after 30 seconds the
display should return to normal. NOTE the position of that single LED should you see it.
1) Self-Diagnostics in the initial Power ON
1-1)The control board performs a self diagnostics test within 1 second and check out the temperature sensors abilities.
1-2) If a sensor failure occurs, a corresponding LED segment will blink with a beep.
1-3) When a LED segment blinks, only the cancellation function (Press Power Freeze and Power Cool buttons
simultaneously for 8 seconds) is acceptable.
1-4) After a replacement of bad sensor or a cancellation of this function, this self diagnostics will end.
2) Self-Diagnostics in the normal operation
2-1) To select this function, press Power Freeze and Power Cool buttons simultaneously for 8 seconds with an audible tone.
2-2) In the self diagnostic mode, only corresponding LED segments will be illuminated (see the check list on the next page) <NOT in this post Interpreting LED position = these errors below. You will need to pass on / reply with exact position of the LED that you see
1 ICE MAKER SENSOR
2 REFRIGERATOR SENSOR
3 REFRIGERATOR DEFROST SENSOR
4 REFRIGERATOR FAN ERROR
5 ICE MAKER function error
6 CoolSelect ZoneTM SENSOR
7 REFRIGERATOR DEFROST ERROR
8 EXIT-SENSOR
9 FREEZER SENSOR
10 FREEZER DEFROST ERROR
11 FREEZER FAN ERROR
12 CONDENSER FAN ERROR
13 FREEZER DEFROST ERROR
2-3) After a 30 second illumination of error signal, the system will return to the normal operation.
I suspect a thermistor problem.
The unit will self diagnose if you unplug it for 15 to 20 minutes and then plug it back in. ANY errors will be displayed by a single LED (digit) indication during the first 14 seconds after you plug in the unit.

You must wait that 15 - 20 minutes of unplugged time to prevent the compressor overload from tripping due to high coolant pressures. System must stabilize first to prevent damage to your unit.
