Frigidaire GALLERY will not make ICE or dispense WATER at door. Plenty of water at the NEW filter I just replaced.

Did you try getting the AIR out of the line by running the water dispenser unit for a few minutes? Here, most of these refrigerators have long tubes inside the 'fridge and they need to be purged of air. If you push the water dispenser button and hear an audible hum then be patient and wait there with a cup in hand until water flows. Once water flows, run a half-gallon or so to clear the line of filter sediment. I'd also throw out the first batch of ice... ;)

Back to you...

PS: Make sure the water line shutoff is fully opened!
