Dyson v15 problem with the dust detector board

[PNI E.]

Hi guys, I have a Dyson v15 that didn’t work. The battery blink 10 times. If i disconnect the cable of the dust detector board, the Dyson turn on but after some seconds stop because didn’t feel the flow of the air because I disconnected the bird sensor, if I connect the Dyson is death. I notice the big mosfet I think with 3 pins. If I check the mosfet I have a short circuit from the center pin ne the left pins…so I think that s the problem or I wrong? The problem I can’t understand what type of mosfet is….someone can help it s hard to find. New board

What is printed on the SOT223 mosfet? N channel or p channel MOSFET uses depend on where they are used like high side or low side switching.

thanks for your answer. im not really good. but what i underand the problem is on that board in the photo, and i check every caps and they are ok. the only short i have is from one pin and the center of that mosfet on the red circle. first i dont know if that is the problem...but should be there.....abd they erase all the name of the component so i dont know how to understand what type of mosfet is...can you help me to understand what type of mosfet is....if it s a mosfet thanks
