Dometic refrigerator frost and ice

[rollindownthero]

I bought a used 2018 Prime Time Tracer TT in April. Only used it on weekends initially. Moved into it full time a month ago. I'm getting frost in the freezer on the back wall and ice on the fins in the refrigerator. Is this normal and do I just need to defrost it? Or does the seal need to be replaced on both? This is my first RV.

Thanks for your help.

Quite normal. Unlike home refers, RV units do not have a defrost cycle.

I am in FL. The seals don't look like they need to be replaced. I didn't know if this was normal for an RV refrig or not.

If you're in Florida it is just the humidity getting in everytime you open the fridge door. You can search here and put in a small computer muffin fan to circulate the air in the fridge. Very common problem.
