Electrical diagram of the Durst UT 100 dryer

[Alain Allovon]

Hello, after a long period of inactivity, the fan of my dryer does not work anymore.
I would like to try to make a repair.
However, I don't have an electrical diagram, if you have one, could you send me a copy
Thank you in advance.

It might be stuck due to inactivity - it happened with my Jobo Film Dryer. I sprayed some electronics cleaner in the shaft, plugged it in, turned it on and it worked like a charm.
I hope it will be as simple with yours.

If nothing works, suspect the power supply to the switches. If the elements heat up and the fan doesn't turn, the fan may be seized.

It's a relatively simple design so it may be safer to leave it to an expert to fix if you are unsure?

Hello, thanks for your answers.
The fan is seized. By insisting a little with some degreasing agent, I was able to restart it.
Thank you very much.

I have not fixed Durst anything

But I have discovered there are many fan options

Match the air flow not the size

Here is an example that most likely is NOT right for your problem

I have put this type inside enlarger heads to replace a failed fan

Hello Tin Can,
I found on this site : https://es.aliexpress.com/item/32825170965.html?spm=a2g0s.9042311.0.0.274263c0Htnhdt a fan close to the Durst dryer UT 100.
I just ordered it.

Thanks for your suggestion.

Hi Alain,
Can you please let us know if this is the right motor (fitment & all)?
My UT100 fan is showing some hesitations and I might have to change it as well.
Thanks!
