Product review (2 stars): surprised it was louder and more difficult than I expected
I have an original sub zero refrigerator and a freezer in a separate unit.  Same size next to each other, had to replace the freezer motor with this SUP product and was disappointed it was louder than the fridge.

In addition, no instructions and a lot of extra parts!  It would have been nice to have some details, not even anything on the factory website to look at.

When replacing, it isn't easy getting the motor mount screws back in.  I used the MacGyver technique with duct tape on the rubber grommet and nut to hold in place, it is too tight to fit a normal hand behind the product to hold the nut.  it worked by tightening the front two screws first which helped the alignment, then do the back one.

My freezer is back to working normal... just a little louder.

good luck.
