The fridge came with the new house we bought. Fantastic looking fridge. 

We have noticed that the fridge part is running warmer than usual and the freezer works perfectly. We first noticed there to be a problem when the doors were constantly sweating and pooling water on the ground. I eventually did some digging and noticed inside near the crisper was an ice block.

My wife and I took everything and put them in coolers to defrost. I took off the panel covering the evaporator coils and sure enough it was one big ice block. We defrosted the fridge overnight. Plugged it back in the next day and was working perfect.

Now fast forward two weeks later it is happening once again. Is it a bad defroster? The defroster sensors not working properly? I'm stumped on what is going on and have noticed a few other people having the same issue.
