"Cycle Defrost"--once again I learn something NEW!
I'm afraid it's my lack of understanding of this concept...
So, if the fridge section has gridwork, above the fresh-food area, does that deem it Manual Defrost? And if it doesn't, but the freezer wouldn't be self-defrosting, in case of the fresh-food area, as in one resembling one that's Frost Free?
I remember some flea market I went to having a bunch of Avocado Green top-freezer Frigidaires (there were also matching electric ranges bad other misc. appliances) saying "Cyclematic", and Whirlpool termed this system "Automatic" (Sears Coldspot probably did too) much like what this Philco does, whereas I've seen Amana's "Automatic Refrigerator" also employing this concept... Ditto the General Electic and Hotpoint with the three '+ + +'s (pluses)...
