I have a new Frigidaire Gallery, bottom mount, fridge with a built-in water dispenser and ice maker.
I installed the water line about a month ago, it's only a single water line running to the fridge. So the water dispenser and ice maker run off the same source (one connection on the fridge). I tapped into the kitchen sink's cold water supply.
When I installed it, it immediately began making tiny ice cubes, which I thought was annoying but decided it must be "normal" since it was the first cubes it made. It filled the entire ice compartment with these small cubes (about 0.5" cubes). Then it didn't make any more ice, ever. I didn't notice it stopped making ice because I rarely ever use ice in the early spring, but the buffer ran out and I'm noticing it's not making any.
The cubes it made were not hollow, they were solid little ice cubes. So it is possible that they are the correct size.
There are some frozen cubes up in the tray (I felt in there for them), but it is not releasing them. Perhaps they are too small.
When I use the water dispenser, it seems to be fast, much faster than my old fridge. So, I don't think there's a problem with my supply line. ...but how to I verify that there's no problem with my supply line?
It takes about 10s to fill a glass, which I thought was pretty good, because it's about as fast as my kitchen sink.
When searching through issues with ice makers I am seeing a lot of problems with slow water supply causing an ice maker to fail. However, honestly, how much water pressure does the ice maker need? Is it a big problem if it takes 10, 20, or even 30 seconds to fill the tray? Do most ice makers meter water based on time? That just seems wrong. What if the tray is filling while I'm using the kitchen sink?
This might seem like a lot of questions, but the bottom line is "How do I verify my supply line is good enough to feed my ice maker?".
