The first one came and would get cold with having a loud hum.  I assume it was from shipping.   Wayfair was excellent and sent out another one bery quickly and this one works great.  It does run almost continuously so we are going to have to see what our power bill looks like next month. 

Update:   The second fridge I received started heating up on the top zone as well.  I unplugged it, took off the back and found the cooling fan was frozen.  I went to Amazon, found a 92mm, .01 amp fan for under $6, ordered and installed it.  All the fan is, is a computer cooling fan that fits perfectly.     Works great and much more quiet than the original, chinese made fans.  I ended up buying 2 more fans, also fixed the first one that was sitting in garage and now working perfect and  have a back up replacement fan if/when another one goes out.  If your fridge stops cooling, this is an inexpensive fix and you will have a better and quieter fridge.
