Product review (5 stars): An easy Fifteen Minute Repair Product
Had a very positive experience with installing these replacement cams, particularly after viewing and improving on a couple of YouTube tutorials. It is actually possible to install them WITHOUOT removing the refrigerator or freezer doors, or emptying their (frozen) contents. I DuckTaped the doors in place and supported them with a jack stand while doing the replacements.

These appear to be genuine OEM parts, good quality. I recommend using the synthetic grease (Super lube 21030.
