Yes, a 49-yr old woman fixed this fridge all by herself! AppliancePartsPros was very helpful in the diagnosis of the problem, which I determined to likely be the result of defrost failure. There was a large amount of ice and frost coating the back of the freezer despite the inside temp being 42 degrees. My husband thought I was crazy to think it was a problem with ice when the temperature was warm, but I told him to trust me and I would attempt the repair. He just wanted to throw the old one out (10 yrs old) and get a new one. But I stubbornly said I wanted to a chance to repair it myself - yes a woman repairing a fridge - oh no! So I purchased the three components of the defrost cycle for repair, watched the videos linked to the parts and got to work. When the ice was gone, I took the heater out first for inspection since that was easiest to get to in my GE. A quick look revealed that the ceramic housing for the heating element (a single element heater) was crumbling and it didn't take much force for it to fall apart completely. My smoking gun! Or actually not smoking which was the problem. The dual-element heater replacement didn't have a video, but there were clear written instructions provided. The only thing that didn't quite match up with the instructions is that it said that the pink wire would be on the right and the blue on the left for a metal heater casing. My pink wire was on the left. The instructions anticipated that switching to the dual-element heater would require splicing new wire in to lengthen the pink wire long enough so it would reach the same side as the blue wire. So I had to do some wire stripping and splicing. My husband had all the necessary tools because at one point in his life he had worked on houses, but now he just works at a computer all day. The instructions also made reference to something that I had to Google and learned was silicone caulk. Luckily he had some of that laying around too, so that part was easy. To his credit, he did set up the caulking gun for me :). I think he was secretly hoping that my repair would fail and he could both gloat and buy a new fridge, BUT it's been 5 days and we are down to 0' in the freezer, 36' in the fridge and NO frost buildup. Woot! Victory! [Although I put that it took 1-2 hours, defrosting actually took the longest time of the whole repair (~1 hr), with the actual active me-and-screwdriver repair part taking about 30 minutes, then 3 hours for the silicon caulk to cure.]
