I have been full timing for 2.5 years have a 3500 Big Horn very little trouble. I live in Texas where it is HOT, My dometic for first time is not keeping food in Fridge at acceptable tempertures. The freezer is fine everything is staying frozen there. I don't understand why air from freezer is not falling down in bottom to keep the temp about 30-40 degrees which is need to keep milk and other such food from spoiling. The temp stays at about 50 degrees. I know it hotter now but it has kept the right temp up untill now. Can someone help and give me some clues as to what is wrong. I am having a hard time to get someone to commit to come out. I have a service contract with $150 DEDUCT so money no problem...Help Thanks..
