Norcold spec'd clearances of 1/2 -3/4" for the plenum for the airflow and mine was almost 2". I removed the unit and corrected the enclosure size to Norcold specs with little improvement. Ventilation isn't an issue, I've been round and round and have supplemental fans for supply and exhaust and all airflow goes thru the cooling fins at the top.
I'm almost ready to yank it out and replace with a conventional unit.
I'm not a fan of the Norcold, however regarding the clearance distances you quoted above, I may be wrong, but I think what norcold quotes are the MINIMUM clearances, not the exact, so if they recommend 1/2" to 3/4" and you have 2", then clearance is not the problem. Generally you have problems when the clearances are LESS than those recommended. I believe you need to look somewhere else for your problem. If the freezer section is mid teens and the fridge section is mid 50's, I suspect you have a poor seal in the door gasket, letting cold air out and warm air in to the refrigerator section. Do the $ bill test all around the seal to ensure that you have a good seal.
Personally, if it were me, I'd replace with a residential fridge. Replaced ours 6 years ago and never looked back! Extremely happy with it!
