About a month ago I bought the Pimoroni Fan Shim. It worked perfectly well until about two weeks ago it became very loud. The problem persisted. Then, today the fan didn’t start when I programmed it to, and it didn’t start until I spun it with my finger.
Based on what I saw from other people’s experiences and from my experiences, it appears that the fan is “rubbing” on its axel.
Can I fix this, and how?
