Product review (5 stars): Water flow may take longer to start than suggested on YouTube videos
Successfully used the part to fix the frozen line in GE water dispenser.

If you followed the instructions but do not see water flowing after 30 minutes, I suggest you do the reassembly and check for flow on the next day.

This was my experience:

I followed one of the YouTube videos. The video suggests checking for water flow before reassembly.  In my case,  I did not see any water flowing, even after an hour. So I reassembled the unit, assuming the part did not solve the problem.  I was happily surprised the next day when someone else tried the water unit and found it was working again.
