A lot of the Dyson fans nowadays have the ability to oscillate. Throughout multiple versions, there have been some reports of a clicking noise developing at different amounts of use time. Unfortunately at this time, there doesn't seem to be a clear solution to the problem.

Winix C535: Motor is making a Wha Wha Wha noise

Tue, 03 Feb 2026 12:51:26 -0700

The noise is definitely coming from the motor and the frequency of the wha wha noise increases with increased fan speed.

Is there a replacement motor available?

Brondell air purifier: Device does not reset or turn on - How to find spare parts?

Wed, 03 Dec 2025 16:09:35 -0700

We were given a broken Brondell (also branded Aktobis or Winair) air purifier. It stopped working when changing filters and Brondell doesn’t offer repairs or spare parts. [Edit: We followed all reset procedures suggested by the owner’s manual]. The device briefly turns on before turning off again. Resetting does not appear to work. There are no apparent damages to the boards (there are three, the main control board, the CO2 sensor and the user controls)

We have already tried replacing the power cord to no avail. We can’t find the problem, and can’t find spare parts that’d enable to switch and test the boards. Any recommendations?

Dyson am09 hot cool heater fan: Fan won't turn on (main fuse blown)

Mon, 17 Feb 2025 10:18:54 -0700

Hi, my Dyson AM09 fan was knocked over and stopped working. I've taken it apart and noticed the main fuse (F1) doesn't have continuity running through it. The rest of the circuit board looks fine (see images attached). However, I'm relatively inexperienced when it comes to electronics. If I replace the fuse, is there any way to ensure it doesn't instantly blow again?

I'm also struggling to locate the fuse (46211600000) in the UK. Would any T1.6A 250v fuse be a suitable replacement/ are there any specialist shop in London where I could locate a replacement part?

AlexaPure Breeze: Repair of Alexapure Breeze; fan Startup Fails

Sat, 28 Jun 2025 15:25:44 -0700

Alexapure Breeze on startup lights sequentially light up,

then back down, then off. Repeats with subsequent attempts.

Filters have been replaced. One Electrolytic capacitor replaced that had bubbled.

Tested and no change,

it Will not start the fan, just repeats light up and down sequence

and I had just purchased new filters for it thinking that was part of the problem.

Nope. I have not isolated the problem yet.

Dyson am09 hot cool heater fan: Won't turn on suspect it's the tilt sensor on the PCB.

Wed, 12 Oct 2022 21:05:51 -0700

I have a Dyson am09 that has stopped turning on with both the power button and the remote. The remote is working and I am getting power through to the board. On further inspection there is a rattle coming from the black component rbs310910 in the image. I'm presuming this is the issue but could be completely wrong. Anyone got some advice? I'm unable to find the board with components online

Vax AP01: Faulty Vax AP01 air purifier, need help sourcing components

Sat, 26 Jul 2025 10:35:41 -0700

My Vax AP01 air purifier broke at the weekend, plugged it into the wall socket and heard a pop, now it won’t work at all.

Opened it up to find a coil/inductor has blown as well as some burn marks next to a chip with the markings VIPER12A F24610. Which i've found this as a possible replacement? https://cpc.farnell.com/stmicroelectroni...

I'm reasonably handy with a soldering iron but not very good at problem solving circuit boards. I am looking to purchase a new coil/inductor to replace as well but no idea which one to buy. The colours are BROWN - BLACK - RED - SILVER

I contacted Vax but they cannot supply a schematic or any replacement parts so here I am.

Any help would be greatly appreciated and thank you in advance!

Hi @jayeff

Thank you for the reply! That's a great help. I searched the board numbers but unfortunately didn't find any results.

I did however notice the fan had 220v AC printed on it so decided to crimp this directly to the power cable. (I'm in the UK so our household sockets are 230v) It's fixed on medium speed but it works until I can source the right components
