I purchased a Fan Shim for a Raspberry Pi 4 (4GB model) just over 2 months ago. It’s been running continuously since, but yesterday afternoon I noticed the fan no longer spins at all, and I can’t get it to work again. Can anyone help or advise?
I tried unmounting and remounting the shim but that didn’t help. I’ve tried a clean install of latest Raspbian Lite, with all updates via apt-get and the latest fan shim software from GitHub, and it still didn’t work.
I then tried it on another Pi 4, clean install of latest Raspbian Lite with just the FanShim API (pip3 install FanShim), and tried running the following manually:
>>> from fanshim import FanShim >>> fanshim = FanShim() >>> fanshim.get_fan() 0 >>> fanshim.set_fan(True) True >>> fanshim.get_fan() 1
Sadly it still didn’t work, and I can’t think of any other way to rule out software issues, so think it might be a hardware issue with the fan itself (does anyone know the best way to contact pimoroni about this?)
By the way, I can illuminate the LED using “fanshim.set_light(0, 255, 0)” so I know it’s getting power/data via GPIO, but can’t work out why the fan suddenly has stopped spinning at all.
