To reset and 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- Press and hold the LL Keypad At this point you're holding two keypads
3- Release the Water Keypad and wait 3 seconds At this point you're still holding the LL keypad
4- The control will display PE (Programming mode) release the LL keypad
5- Press the LL Keypad once more
6- The control will display the current program code (the program code should made the 4 digit code listed on the model sticker near the ceiling of the refrigerator section)
7- If the code is correct, 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.
Now if that doesn't reset your board to working normally, the main relay board on the back of your refrigerator behind a small 8" x 8" access panel needs to be replaced I'm sorry to say.
