RV Repair: RV Refrigerator problem, rv refrigerator, frig

Question
My Domeitec RV frig works fine on all 3 energy sources when the RV is parked. 40 degrees main box and 0 degrees freezer. Will not stay cold when RV is moving on the road. Box temps go from 40 degrees to 55 in less than 2 or 3 hours even though I've tried it on all 3 fuels, ie gas, 12 and 120 volts while traveling. It works on all 3 fuels but won't stay cold while moving no mater which fuel I use. Can you help?

Answer
Hi Bob. Thanks For the Question. The door seals may need to be changed. Use a dollar bill and lay it across the seal and close the door on top of the bill. See how tight the seal hold the bill. move around the entire seal. if it move or is easy pull out. Have the seals changed. Good Luck
