we are on our first shakedown trip in a new van. The fridge lights ok on gas and a quiet blue flame is visible through the bottom external vent. Shortly after this the flame increases and turns yellow/orange and makes a roaring sound. This can’t be right can it? I’ve tried a few times with the same result. Previous van fridges have always been been quiet. Second question, we are parked up on the sea front for the day in very strong winds. I’ve noticed a draft coming into the van around the fridge casing. That doesn’t seem right either? Do we add both of these to the snagging list for the dealer (along with the missing doors from the bathroom cabinet amongst other things) or is there anything we can check?
