Looked up parts based on fridge model number, watched videos, and replaced parts using just a few tools... easy. Parts came quick, well packaged.
After 16 years, plastic parts deteriorate and break. The fridge was operating fine, but the drawers and covers were failing. Much cheaper to replace a few parts ($$-$$$) than buy a new fridge ($$$$). The new parts matched up exactly to old ones. The videos were very helpful, but not perfect... for the Crisper Frame, there was a structural metal channel in the old frame that I removed and inserted into the new frame but which wasn't covered in the video. In another case, the head of the repairman blocked the view of how he was reattaching the Pantry Endcap temp control rods and parts, a step I was having trouble trying to do without breaking the plastic parts. BUT, there were tricks to doing the work the videos covered very well that were not otherwise obvious... why most people would just call a serviceman and pay a few hundred dollars more.
The videos show working on a new clean refrigerator, and working quickly. Mine was not clean. Between very carefully and slowly removing, cleaning and replacing the (irreplaceable) glass shelves, and washing the old parts and interior of the fridge, the job took a lot longer for me. But I had no issues doing the work... simple tasks *if* you know the "secrets" for doing the work. After disassembly, I also discovered other broken parts, which I purchased in a second order... not sure how to get around that unless you first take everything apart and put it back together before ordering.
