Fridge coils icing up
Our Dometic Fridge coils are iced up with a thick coat of frosty ice. I think the fridge is cooling (we do not have a thermometer), but my wife thinks it isn't cold enough. The freezer and icemaker ...

Can circulating fan(s) inside the refrigerator help-- SURE.
But, limiting the intrusion of hot, humid air into the refrigerator (from whatever source) is also important. Not sure a debate over which is more important is relevant.
What the fan(s) can do by circulating air over the fins is keep the fin temperature above 32 degrees F. So, moisture can condense (and take cooling BTU's to do so), but it then drips into the tray and out the condensate tube. Is this a good idea-- sure.
Combine this with minimizing the amount of moisture intrusion into the refrigerator and you have the BEST answer.
You will never be able to limit the amount of air that enters into the refrigerator. Using the refrigerator as intended allows this moisture to enter. We even accumulated ice while we were in the desert of New Mexico! At less than 10% humidity!
Any air that passes over the cooling fins will cool to its dew point. If there is no air flow, that means ice will form. Constant air flow means that the fins do not have to be below freezing to cool the inside of our refrigerator. It seems that the increased air flow allows the thermistor to sense the proper temperature soon, so the fins do not have to be below freezing to maintain , say, 34 degrees in the refer.
The increased air flow allows for the thermistor to sense temperature drops or spikes much faster... Fin temp is immediately transmitted throughout the fridge.... No need for the fins to even be below freezing....
Hope this helps...
