Noise from Fan area. BAUKNECHT 3XKGN701000 (85080101000) Freezer.
There's a noise,as if something is in the way of a moving part.
I took the panel off to observe, fan moves freely , so i ruled it out.(even though i noticed some play up and down, but i was thinking maybe that was factory tolerance).
Please any other noise causes..

Thanks.
