I’ve got a FanShim on a RPi 4. Every once in a while, the FanShim will stop spinning despite the Python lib reporting it as on. If I go “flick it” (for lack of a better word) with my finger, it will restart and then continue to operate for a period of time (anywhere between an hour or so and a day or two).
I’ve looked at the GPIO connections and it looks fine (especially pin 12/GPIO 18) although I may be missing something. I initially thought that dust might have been interfering with things but I’ve cleaned out the RPi with compressed air. Any thoughts as to what the issue might be?
