Hi,
Here's the parts diagram:

#15 is the bracket support, that may be the issue, read below:
I'd first check the dispenser bracket that holds the ice dispenser switch in place, to make sure the little plastic pins are not broken.
The most common issue when this happens on your model is the bracket support plastic switch pins break, thus no water or
no ice.
You would need to remove your front dispenser frame #23 in that diagram.
Then look at your support bracket #15 to see if the little plastic pins are broken that hold your ice and water dispenser switches #14 in place.
Here's the dispenser bracket for your model you can order(Video Included in part link):
