If the mosfet Q5 is below 5V, does that mean it's broken?

Hello,

I'm trying to add a cooling fan and connected to PWM slot but it doesn't work. The fan was tested and it works fine.
I have Prusa i3 Pro B with GT2560 board bought in September. I use Marlin and in the firmware, PWM fan Pin is 7.
Tizzy, you said connector 14 is a PWM fan connector. Did you ...

Hi, ggg666,

I controlled the fan 0% to 100% from Repetier and at 100%, PWM Fan slot voltage was 0.18. Should it be 5? How do I fix it?

I sent M106 code from Repetier but nothing happened.

Pin 7 is set to ...
