I noticed the icemaker wasn’t making any new cubes. I discovered the water filler tube had frozen water in it, so I removed it, cleared the ice out and reinstalled it.
Two days later, I still don’t have any new cubes because there’s no water filling the tray. Other parts of the icemaker - the part that would lift the cubes out, for example - are working. It’s just not adding water to fill the tray.
Thanks for your assistance.
