My friend has a 2012 Montana 3400RL with a Norcold Refrigerator and have a problem with it running on electric. It seems to run okay on propane. While it is on electric it will go for 3 days and it shuts off and then the fins in the back drips water. Can reset refrigerator and it will run for about 3 days and then shuts off again and starts to defrost. Seems like the fins in the back freeze up and then when it gets really bad it shuts off. Not sure if related. Has anybody heard of this problem

I can't adress the propane vs. gas operation but excessive water build up and icing can be the result of door seals not sealing. Nothing works right on these if the seal on each door doesn't seal properly. It is a common problem with these.
