This is a standard Dometic RV absorption fridge mounted in a slide out which if not properly vented will deliver less than ideal cooling, particularly as outdoor temps rise. We do have internal fans in our motorhome's Norcold and in our TT's Dometic that I hardwired in, both do a great job moving air in the fridge and preventing frost build-up. Our absorption fridges have worked well for us but on a couple of rigs I had to improve flow behind fridge, how RV manufacturer installs them, especially when in a slide out, is critical to fridge reaching maximum performance. Might need to go back to dealer to determine if unit is properly installed.
