The one old style turns on and off like your furnace. The new ones run at different speeds trying to think ahead.I wish I could help here but I have absolutely no clue. I'm not familiar with those cooling methods. I'm interested to learn more if people have feedback though.
That's what I always figured too. Putting the freezer on the bottom seems like an extravagance, fighting an uphill battle against physics. But maybe I'm wrong and it's the other way around, and the cold air "pools" in the freezer so the freezer doesn't have to work as hard?In the over/under door models, I think the top freezer is more efficient, since some of the freezer cold just drops down to cool the refrigerator... whereas the bottom freezer models have trouble getting cold to go up... the old 'heat rises'...
LOL! I rest my case... an overly expensive complicated solution to a simple problem... although I can see shorter people or people with certain health problems preferring the bottom freezer...We have had a sub-zero for 5 years now, bottom freezer. Love it. It has separate compressors for the freezer and the fridge. They are expensive
Not defending LG at all, but my LG fridge is the only thing that lasted between that, the washer / dryer and dishwasher (2014). There's a lawsuit for LG fridges, but mine isn't one.Stay away from LG and ESPECIALLY Samsung! Many, Many problems!
We bought a Whirlpool French Door, 36-inch Wide French Door Refrigerator - 25 cu. ft - WRF555SDFZ
The ratings on it were excellent, and like Flyover said, a SxS prohibits you from putting in wide items. This is WIDE AND DEEP! We especially like
the meat/cheese drawer. Price wise, its <$2000.
Check it out. We bought ours at Lowes. BTW, they're Made in America!!
