Part Cooling Fan not working correctly

[Tyrant]

Hi , I have a A10 printer ( REV B ) Board . my part cooling fan for filament cooling is no longer working correctly . when i Turn the printer on, the fan runs very slowly without a print running. this continues when printing. have replaced fan , Same issue. even through repeatier host i'm unable to control the speed of the fan.

i suspect it's something on the board itself. I've done a bit of research , and think it could be the mosfet SOT-23 AP2306AGN transistor.

Can someone advise where this is located on the board ? perhaps with a screenshot? i'm not that good at reading the schematics of the board itself.

thanks in advance

I think you are talking about the Q2 part.
It is under the E0 motor driver board.

Hi,Tyrant

You have mentioned it at your first post:SOT-23 AP2306AGN.
The Q2 part use the SOT-23 AP2306AGN for it.
