I am asking this out of ignorance so please don't take it the wrong way, but when we defrosted our old Frigidaire with a shelf for the ice trays which was surrounded by the evaporator, mom just put trays of hot water in to melt the ice, those being the days before blow dryers which we used to defrost the WH chest freezer in the 70s. Couldn't the GE have been defrosted in a similar fashion? Before we got air conditioning, the freezer would have to be defrosted twice during the summer. Getting a frost free fridge was a real priority for her, but as it worked out, we got the AC before the GE Frost Guard. It did cut down on the defrosting, but it was still a messy job.
