I have shut off power to it so it won't make any more noise...but I assume I need to replace the transformer...here is a pic of the chime:



Can someone help me figure out what is going on in this pic? This chime is 20 years old. Can I just replace the transformer or do I need to replace the entire thing?

Update 1: I changed out the transformer and the chime was still buzzing.

Update 2: I removed one of the wires on the doorbell button, as suggested in this thread and the buzzing stopped… So my button is bad and I am going to take this opportunity to install a Ring doorbell.

99% sure it is just a transformer swap. Generic piece available on Amazon. They seem to just fail and get stuck in either an open or closed position.

You probably need some numbers off the existing one to match the voltage. But something like this would fix it up.

My old one did that because the doorbell sometimes got stuck when someone pushed it.

Press on the spring plunger things and see if they move up and down easily. If not try lubing the plungers. If that fails replace the transformer.

Do you have a video door bell? Some of them require a jumper. Mine started buzzing after a while then I realized i needed the jumper.

Disconnect one wire from push button. It may be stuck as mentioned before.

Those plungers in the chime get sticky and need to move freely. Push them down and see if they have free movement. If not, try to clean them or replace the unit.

Does the unit function aside from the buzzing?

can I step up the transformer to a 16V/30VA in the event I get a Ring one day, or do I need to match what I currently have? I am electrical idiot, even though I did take one semester of Electrical Engineering at LSU.

Voltage must match original. Higher VA rating won’t hurt anything.

thanks for all the advice in the thread...I am going to try to replace the transformer to see if that works...

Ring provides a little booster that helps with lower power chimes. Instructions would be inside on what to do, if that's what you are talking about.

The buzzing is most likely caused by a switch stuck in the on position. That keeps current constantly flowing to the solenoids. Normal functioning uses only pulses. As suggested, open the button and remove one of the two wires. If that makes the buzzing stop, replace the button.

The lettering in the pic is hard to read, but in two places it says "do not oil". Lubricating may be a bad idea on your model.

My limited experience with old solenoid chimes is that some run on 24V with the transformer piggybacked on a light socket in the attic.

Make sure the door bell button is not stuck. As for ring doorbell. They are great. It uses the low voltage from the doorbell wire, to charge the ring.

I changed out the transformer but the buzzing continued.

So, I want to check out the button now but the two little screws that secure them to my porch wall are stripped.

Now, I need to get them removed before I can do your suggestion.

Are the stripped screws in wood?

Try to put a razor blade behind the head of the screw and pull outward while unscrewing with the screwdriver. You can always use bigger screws or they make an epoxy mixture to fill in the holes when you put them back in.

eta, sorry, I thought the screws were spinning in the stucco

If it's a surface mount type, you could probably yank it off with pliers. Then get a new one, as the button is likely faulty anyway.

You could then move it over a little to cover the old screw holes and drill into new stucco.

Or cut slots in the stripped screws to fit the screwdriver.

Lots of options.
