My garage door opener is humming but is working just fine. Is that a fire hazard?

How about more information. Hum all the time or just when it is
opening/closing? Did it just start or has it always done it?

Motors do hum when working.

In my previous house I installed an opener that hummed. The only tune
was 60Hz and maybe some harmonics of 60Hz. It was the transformer that
provides low voltage for the buttons to manually control the door. It
did that for 30 some years and is probably still humming. If it were in
a place where I spent lots of time, I would have probably replace the
transformer. BTW, it was worse in the winter when the garage was
colder. Occationally, in the winter, I could even hear it in my
bedroom, which was above the garage.
