I have got the above american style f/f 858644515020. The problem is that the air diffuser and channel get blocked up with ice causing the motor to stay in the closed position. once cleared it will work ok but not well until it builds up with ice again. on inspection i have found that the diffuser is always opening and closing it never stays in one position, i think that this is where the problem is or should it do this, if not are we looking at a new board or a sensor but looking at the board it is £129. any help about this difusser would be a great help
