If you look closely at the construction of "Amish" unit, and all other cooling units, it's easy to see where ONE bad weld will result in a weak spot.
That's what happened on my first "Amish" unit.
And, on the replacement unit I discovered it needed additonal airflow through the consendser (upper coil).
And, in the last few months this one is not cooling like it should. It cools to 10 degrees in the freezers and 46 degrees in the food section.
I'll be calling David Force very soon.
Incidently, the original Norcold unit worked perfectly for 7-1/2 years. I'm considering buying another Norcold.
