Product review (5 stars): Totally a lifesaver
So we bought our fridge in mid-2013 since we closed our house, it has been an workhorse until this summer, we noticed the entire back panel is frosted and had to use a hair dryer to melt the ice. The fridge will then work for around 7~10 days and we will have to repeat the process.
Finally after going through countless tutorial video on youtube, we nailed down to this defrost bimetal piece that was causing the issue. The replacing is simple, barely took us five minutes, now the fridge is back to normal, most importantly, my wife get to freeze the breast milk for the baby again. Totally a lifesaver!
