Ice maker fill tube recently froze solid with ice, and I assumed was no longer heating so replaced the entire fill tube and heater assembly with new part. Ice maker worked fine for a few weeks then new fill tube is now also completely frozen. Noticed while the ice maker was working again there was often an icicle hanging down from end of the fill tube. Any input on what the issue might be is much appreciated.
