Looks good, Louie!
A thick accumulation of dust and cat hair on the condesner killed the compressor on my sister's refrigerator. I don't think she ever vacuumed under there. Maybe that's all your fridge needed.
I agree that there's no way to remove all of the dust from the condenser with a vacuum or a brush. The crevice tool is limited in where it can reach, and there are areas that can't be cleaned even with a brush that's supposedly designed for this purpose. I do what I can, every six months to a year, and that seems to be enough. Not just on the '57 Combination, but also the '09 KA, which supposedly doesn't require vacuuming, but I do it anyway.
