Tower fan: Everything works, except the blades...
edit: I’m in the process of testing the capacitor on the circuit. See the full story in comments below if you’re interested lol.
Also, the “burn marks” on the circuit, in the pictures I linked, aren’t burn marks - merely bad quality pictures.

Hi, I’m new here and also new to repairing stuff.
I’ve tore my fan apart, but I don’t really know how to diagnosis the problem. Visually I can’t see anything that seems wrong..
The buttons all work, the lights lit up when I press them, it still beeps annoyingly loud and the base still turns (from left to right to left..).
But the motor that’s supposed to make the blades spin looks dead. I detached the tower blades from it and the shaft just doesn’t move when I turn on the fan…
Except I’m thinking: it can’t be dead, it’s just copper wires and a metallic piece in the middle. So current just doesn’t reach the motor I guess? But what can cause this?
What can I do to pinpoint the issue and/or repair it?
Thanks in advance! :)
Edit: Picture of an odd soldering

As odd as it sounds, the motor failing is totally possible, but it's more likely that it's the connection. Have you verified that the wires leading to it carry current?

Hi! So, there's 6 different small wires going into the electric motor, and I detect current in one of them, the black one if it matters lol. I used a device like this https://www.fluke.com/en-us/product/elec...
edit: Alright, wth is happening? When the fan is plugged in and turned on, I detect only current in one of the 6 small wires. BUT when the fan is turned OFF (still plugged), there's a strong current in the entire bunch of wires. ??? Is this thing programmed to just stop working after a while?

Hi @paskual ,
Don't know for your motor but a lot of motors have a thermal switch buried inside the motor (vacuum cleaners are a good example) which operates when it gets too hot and shuts the motor down to prevent it from burning out.
Some also have a centrifugal switch to limit the r.p.m. once it reaches a certain speed.
Again I don't know what your motor has but it may be that it has one of these switches, especially the thermal switch and it has failed to reset once the motor has cooled.

Thank you very much for your response @jayeff . I was full of hopes, but I didn't see any switch... :( here's pictures if you're interested, https://www.flickr.com/gp/145611256@N04/...
