Question trane xv-80 furnace: constant buzzing?

I just purchased a house with a pretty new (~2 year old) Trane XV-80 gas furnace. Everything seems fine but ...

The furnace constantly (whether heating or not) makes a buzzing noise. It is definitely an electrical buzzing -- a rapid clicking, maybe 50 Hz, like this:

not a mechanical rubbing/scraping.

It is not too loud -- but it sounds abnormal so I just want to check whether anyone can recommend whether to do anything about it. Thanks from Seattle.

I bet it's the transfromer... They are not that expensive to replace.
