i have low mileage knaus 708g camper with modern truma blow air heating and hot water supply, was working perfectly,but now hot water perfect but heating wont start and red comes on when it trys.has plenty of water,new gas,new battery,any ideas? is there a fuse maybe on unit for fan that doesnt appear to get blowing and maybe cuts gas supply? as it puts light on as it clicks to start,as i say it is a hardly used good condition camper
