Hi There!
My fan is no longer powering on and from taking it apart as best I can it looks like one of the chips has blown although i'm struggling to identify the part to attempt replacement, does anyone know what this part may be?

Dyson AM07 Tower Fan: faulty fan now board dead

Thu, 02 Jul 2026 03:51:16 -0700

So i have just replaced the oscillating motor and the x2 cap to fix the side to side movement and stop it happening when it's off! the main fan motor was a bit noisy, so i decided to take the impeller off the motor and clean and lube the bearings...bad idea! the impeller ended up breaking the locating lugs off the bottom of it, and after all the messing around, when i turned it all back on, the motor was really unhappy, causing surges and then cutting out completely. tested the fan from a known good machine and it worked for half an hour continuously at 10 without any issue...

I managed to source a second hand unit from a dyson repair shop nearby, and it arrived today - plugged it in, the display came on, motor did nothing...seconds later the screen went dark and nothing worked since. i've since tested the motor, and it seems to have a short/very low resistance between the case and W1 phase wire - obviously it's sent 300v upstream and done some damage!

I've checked the fuse, all the 0ohm resistors i can find, and run through a load of testing with the help of AI to prove the buck regulator, the mosfets and the driver ICs all seem to be behaving as expected. however, after tracing U2 (5v regulator), it seems to have a direct short to ground on 2 pins. from what i can find, it appears pin 1 is output (apart from anywhere else, it supplied voltage to the screen), pin 2 gnd and ping 3 input - which appears to have a direct connection to the buck regulator IC output. thinking the 5v regulator had gone short, i pulled it.....and still have the short. then i removed cap c7 to make sure that wasn't shorting....it wasn't either.

Literally tearing my hair out now (shop said they wouldn't replace the damaged board, but have agreed a 50/50 split on a new board if i have to; but I would rather fix this.

Can anyone offer any advice? any common failures when the motors go short?

Thanks all!

Air Conditioning: Trying to source a suitable air-con

Thu, 25 Jun 2026 16:11:13 -0700

Last year, during the heatwave, I invested in an air conditioner unit, which gave me about 2 weeks of blissful cool conditions until the electrics burnt out. I was able to send the unit back to Amazon and get a replacement under warranty.

Sadly, the replacement packed up after 2 weeks. This time I was unable to get it replaced under warranty, because it was deemed to have been used in an unsuitable way, with the exhaust pipe having to have both a steep rise and a sharp turn to get out of the window. This left me out of pocket to the order of about £600.

It turns out that the geometry of the window in my flat could not have been made any more air-con unfriendly, even if it had been deliberately designed as such!

The height of the window, and the fact that the window is hinged at the top, makes it virtually impossible to have an exhaust pipe that will work without overloading the air-conditioner.

My question is what advise would you give to provide a solution that would suit my window?
