Help to identify a component

[nmac]

Hello all,

This is my first post... and my first consideration and question is: Should I post it here? 

I trying to repair a hair dryer with some rotate function and ceramic stuff... and found this component on image attached.

a slow motor is the issue... probably - and I think - after a broken resistance made a intermittent contact turning on/off this device many times
caused a sequence of inrush current on capacitor and a consequently degradation of it. I don't know, I speculate it could be a capacitor. hehehe But its not the usual info printed on, right?


I can't find on Internet some spec or datasheet for this one.

Someone have any idea what is this?


Thanks!

My first guess would be a filter

That looks like a step-up converter - 4.7kV out. I'd guess it's one of those 'Ionic' hairdryers.

P.S. I doubt it has anything to do with your problem, it's fed directly from the supply and just feeds some sort of spiky electrode near the hot end. The fan motor is usually fed from a tap on the element winding via a (possibly bridge) rectifier. Check for failed diodes. A common reason for slowing down is loose hair wrapping itself around the motor shaft until there's no free play left.

Agree on the loose hair, but also a drop of oil on each oilite bush ( one under the fan so you will have to pull the fan, and get the loose hairball out first before you oil it) of the motor will work wonders. Diodes are also common, but generally you can check in circuit as they tend to go short circuit or break in half.

Thanks for all!

Gyro, makes sense. I'll verify diodes. SeanB, the problem isn't mechanical, but a drop of oil isn't a bad idea.

I'll try those things and let you know if it works for me.

Thank you!

That's it! Just a diode.



Thank you, guys!
I really enjoyed this forum!

Past tense? Ok, fine... Don't forget to close the door on your way out!

hahahaha... using cell phone.. sorry..

I swear I'm still enjoying this forum hahaha
