How can I reduce the vibration noise from my Glow-worm micron?
I have a Glow-worm Micron that is making a vibrating noise. The noise seems to emulate from the extractor fan on the top of the unit. It is a Sifan Systems Model 227034 code No. WFFB1701-031. Do the bearings wear out? The boiler is approximately 2 years old. Should I change this extractor unit if so where might I get one from?
