=== 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.
