My circuit has a mosfet to switch a small fan on and off.
The problem is that the fan will sometimes come on when the control wire is not connected. (My design requires it to be disconnected at times).
I tried using a 100K and even a 33k resistor to pull down the pin on the mosfet but it will sometime still run the fan when the control wire is removed.
Could someone have a look at the circuit?
