Hi I wonder if anyone can help answer my query. I have just found how to keep my fridge door ajar when not in use, a feature that I hadn't realised before! Most useful but I see that the internal light of the fridge now remains on when the door is left ajar. Will this drain my van battery? When I am not away, I always switch the fridge off via the knob inside the fridge but am now concerned if I leave the door ajar to try and keep the fridge fresh and aired will my battery drain? Any help would be most appreciated.
