I have a problem with the internal fan . it makes very loud noise when started cold - after some time it sounds narmal again.
I've tried to oil it but it's very hard to get to the 'bearings" behind the fan-wheel.
Have you found a solution ?
You should get to it behind the lable on the other side.
But most reliable would be a new fan.
There is nothing under that label !
A new fan - yeah, but they are too low quality I think - they should have BALL-bearings
What kind of fan is that?
