Dometic fridge freezing up
I posted this previously in Tech Talk but may be better here.
We have a new van with a 3 way Dometic fridge model RM2553. We've had smaller ones before and no problems but this one has ice blocking about 60% of the fins inside the cabinet after about 3 weeks of continuous operation on 240v. The door seems to be sealed OK when closed and the van is level. It's only set to "3" and has no trouble freezing stuff in the freezer compartment. I defrosted it this morning and will try again. The manual says "defrost regularly" but I would have thought 3 weeks is a bit soon? What is the general experience?
