Both side fans stopped working

Recommended Posts

Hello, both my side fans stopped working yesterday. I would like to replace them but :

_I don't know where to find replacement fans

_I wonder if the fact that both fans stopped at the same time doesn't that the problem may be different than just brokken fans

Please help me :D

Hi SandervG, thanks a lot for your answer! I have an UM2 and I live in France...

I also suspect a loss of connection but I'm not sure where to check


Hi Finyan,

thank you for your post.

Do you have an Ultimaker 2, or Ultimaker Original?

Perhaps the connection got lose, and you don't need any new fans.

Where are you located?

If your fan is broken, you could reach out to Makershop.

If you need local technical support, I would recommend to reach out to them too.

If you want to have a go at it yourself, you can roll up the black braided sleeve (shown here behind the bowden tube, but ignore the rest of the suggestions, because they are about a different topic).

Underneath that sleeve are a few connectors, and your fans are the black and red cable.

Is it loose?

If you are unsure, please take a picture.

Hey SandervG, I've rolled up the black braided sleeve and have noticed that the fans were disconnected. I've reconnected them and everything seems to be fine again!

Many many thanks!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
