the fan of my sensor (type Sensor Community) started to get louder and louder and I’m afraid it is goind to break. Is there a simple way to replace or fix it? The sensor was used a small number of days (<100), and always indoor, with generally very low dust levels, so I’d expect it to be worthwhile fixing.
We too have the same issue with one of our fans. Ours are outside and have been running for nearly 11 months so it is perhaps at the end of its lifetime (I hope not). We have turned this one off because we were concerned that our neighbours would complain! We did clean the sensors but it doesn’t seem to have helped. I hope someone can help.
