Chamberlain buzzing noise

Hey folks, I have just purchased and installed a Chamberlain 1/2 HP screw type garage door opener, and everything works fine (lights, up/down motion, etc). The only strange thing I noticed is that the unit makes a buzzing sound (even when not in operation). I was wondering if this was normal. I took a ladder, and it sounds like the sound is coming from the back of the garage door opener unit. Does anyone have any experience with this?

Same here - sounds like a noisy transformer

Otherwise works fine.

Mine is a belt drive model

We just installed a Chamberlain garage door opener (belt drive) about 2 weeks ago. When we first installed it there was no buzzing... until about 3 days ago. Everything still works fine though.

Has anyone found a solution or a reason for this?

Same thing here. Buzzing that seems to be growing louder. I'm going to have the installer come back out and see if they can fix it. Very annoying

i have a liftmaster belt drive which is made by chamberlain. same noise. i repair garage doors for a living and didnt even bother with it, but i think its a stuck relay. if it is, then its on the circuit board and should be looked at by a pro.
