Ice maker only making a few cubes
I have a 2 1/2 yr. old Fridgidaire side by side refrigerator. Just recently the ice maker is only making a couple cubes at a time. It makes 8 cubes originally. I have full water pressure going into main line which is a plastic line with a filter on it. Line is not kinked. If filter was clogged I wouldn't have full water pressure. Then there's a line that goes up back of fridge to ice maker. Now this I'm not sure of, does water constantly come through that line or only when ice maker needs to fill? When I checked that line it was wet, but no water freely running through. Inside, water reservoir clear,little ice build up where water goes in, I removed. Can't find any clogged ice cubes, wheels turn when needed but only a few cubes are made. Any ideas?
