Unfortunately this is actually a problem with the main control board on the back of the entire refrigerator behind an 8" x 8" access panel. That board will need to be replaced so below is a link to the part, plus you'll need to program the board so I'll give you the instructions on how to do that as well.
CLICK HERE for control board
To program the board: LL, UL and such are the 4 buttons around the display itself which are not labeled (Up/Down arrows). LL is lower left. UR is upper right, LR is lower right.
1- Press and hold the Water Keypad
2- Half a second later Press and hold the LL Keypad At this point you're holding two keypads
3- Keep holding the 2 keypads for 2 seconds then release the Water Keypad and wait 3 seconds At this point you're still holding the LL keypad. Now release the LL keypad.
4- The control will display PE (Programming mode no OOOO after it). If it doesn't show just PE then you have to re-try steps 1-4 again.
5- Press the LL Keypad once more
6- The control will display the current program code
7- If the code is correct (4 digit code number is ***** on the model sticker near the ceiling inside the refrigerator), press and hold the Water Keypad for 3 seconds Press the UR keypad or LR keypad to change the digit value. The decimal point indicates the selected digit. Press the UL keypad to select the next digit.
Once you have the correct program code entered, press and hold the LL keypad until the program code starts flashing. If you try to enter an invalid code it won't flash and the control will beep. If that's what happening try again
