Condensation inside wine fridge

I have a Wine Enthusiast 300 bottle wine cooler I purchased from Costco a few years ago. I am noticing a lot of condensation inside on the back wall of the fridge which has dampened many of the bottle labels and some of the wooden estate boxes against the back wall of the fridge are wet and moldy. Does anyone know how to resolve. I keep the temp at around 54-56 degrees.

I had a similar problem with a different type of wine fridge. One of the fans was being blocked by a couple of bottles that were wedged in close to it. Once I moved those bottles , problem solved.

Ok thanks! I’ll check that.
