neff gmbh extractor glass type setting 1 not working?
i have been called out to have a look at a neff gmbh extractor, the fan setting number 1 does not work, there is a buzzing noise but not extraction, the other settings on the fan control are fine, whats causing this? is the pcb on its way out or is the fan on its way out? or is it just something simple, like a capacitor or resistor?
