=== Problem description ===
The blinds, which you can see in picture 1 as the horizontal white elements in front of the fan, are not closing anymore if the system is turned off. Its not a big problem and the basic function of pushing the air out or pulling it in, is not affected, but the brown/red heating element gets very hot after some time and I'm worried that this could lead to a fire if i leaf it like this.
This brown element on the top right of picture 1 is a heating element, which pushes out a small plastic rod if a voltage is applied on the terminal on the top left of the element, and thereby opening the blinds. It seems that there is always a voltage applied to the element. The light bulb on the bottom right of the picture 1 is lit up and probably indicating that there is a voltage applied to the heating element.
