Fan stops working after going above temperature

[Stew L]

Hi all,

I recently built a Heatermeter 4.2 RPi A+. I am running into a problem with the fan. The fan works all the way until it gets to temperature. Once it reaches temperature, naturally the fan turns off. However, once the temperature drops back down below the target temperature, the fan stops working completely. If I "reboot AVR" then the fan works again or if I unplug the heatermeter and then plug it in again the fan works. I don't know if I missed some checkbox in the software or what but any help would be appreciated. So far I am a big fan of the heatermeter, just need a little help.

Thanks,
Stew

PS-I have looked through the forums but haven't found someone with this problem, I apologize if I missed it somewhere.

Is your max fan speed set to 0? Or do you have it set to "fan only on at max"? Also try manual mode to see if there's a different problem (enter 10%, 20%, 30% etc as a setpoint).
