We have a 2016 Road Warrior 427 and the Hisense residential fridge stopped cooling last August. Found the evaporator was freezing up. I thawed out the evaporator and it would work fine for a few weeks. Took it to Camping World end of last year and they said they could not duplicate the complaint so they couldn't do anything. Called Hisense and they were not helpful. I finally had enough and took it apart last month and started testing things. Found one of the thermal fuses was blown. It cost me 99 cents for a new one. It's been working perfectly now. Just thought I would post in case anyone else has issues. Thanks
