hi.
need help to decide what piece i should replace.
my fridge is cooling well but the display continue to be locked every two mn.
i do unlock by pressing door alarm 3 sec ,and by itself it locks again.
locked or unlocked i cant go to test mode.
what should i replace the display board (inside the fridge) or the main board in the back.
thanks for any help

Usually that indicates a short in the user interface display board. I couldn't locate the part number for it though on your model.
