Had to use cell phone to take a picture of the ID tag with Model# and SN #. With both numbers was able to access parts list from Mfg. Armed with 21 year old parts list is was a snap to get replacement part for 21 yr old refrigerator and installation video from Appliance Parts Pros.com.
Received replacement part 3 days later which sorta looked like original part but updated. Not an exact replacement but after watching the video again.was able to determine even with the updated design it should work. Installed in a few minutes, checked water connections for leaks over night and put everything back together with only a couple of screws left over. Start to finish was much longer than estimated only because I was careful to re-read instructions and re-watched the video a number of times.
The project was a success and its making ice now.
