This is Yarnfan's husband. We recently bought a lunar Roadstar 800. The fridge is a Thetford N112 EES. When the fridge is set to run off the 12 volt supply by setting the buttons on the control panel the blue led flashes saying that it's not getting
enough power. We recently bought the motorhome from a local dealer with three years warranty, should we take it back to the dealer for repair?
