"Every technician said over and over: This is the trade off for meeting industry regulations for new refrigeration appliances. They simply do not have the cooling capacity of the older fridges. They also look at the parts they are installing and shake their heads in disbelief at the change. "
I don't buy that and I think you are getting BSd. On another thread I am complaining about the quality of my KA fridge. This is a new fridge. I opted for the model just going out of production with the slider temp controls rather than the new electronic adjustments, I was thinking less to go wrong.
What the unit DOES do perfectly is refrigerate! Adjustments work well, freezer is perfect, ice maker makes tons of ice, fridge is precisely cool. In fact, it was a little too cold and frosted some of my vegs, so I adjusted it slightly and it cooled right where it should. This bit about the new ones not cooling because of industry regs sounds to me like some major CYA going on.
Maybe if we took your GE trays and fittings and my KA running parts and put them together, we would have one 1/2 way decent unit!
