What causes humming along with the doorbell chime?


Answer by  tweety (266)

Get your doorbell button checked. Take it open and see if there are wires that could possibly be touching each other. A minor short could cause an annoying hum in your chime.

Wires could be shorted anywhere - follow them and check them all the way to the transformer. Did you recently get any work done in your attic? That's where your transformer will be and any work in your attic could have pinched or crushed some wires, shorting them.  add a comment

Well, humming is made by the production of voice sounds. Door bell chime is automatically generated. I am not really sure what you are asking here. But these two sounds can be intertwined with any computer programming. Now a days you can virtually make any sound that is required to be made.

Liz59, what are you talking about? I've never seen such nonsensical babble. You said alot of words without any help whatsoever. You forgot to mention the paranormal, and the neighbors children making the humming sound.  add a comment

A faulty transformer could cause electricity discharge problems and a constant hum.

Transformers and Solenoids - this is what my electrician mentioned when I had a hum on my doorbell chime. I couldn't figure out a bean of what he said, but he set it right working on these 2 parts - so maybe you could try looking at these parts too!  add a comment

The problem normally lies within the Doorbell Button itself, replacing the transformer alone will not do the trick. Go to a reputable DIY store and you will be able to buy yourself a cheap button to replace the old one with.!!

Most doorbells use a 60 cycle AC power transformer. This causes hum in the doorbell's electromagnet. If you used pure DC, it wouldn't hum.

What most likley can be causing a humming in a doorbell chime is a short in the circuit. This could be caused by two exposed wires that are touching each other or a defect in the device itself. This problem can happen to many devices and it not restrictive to doorbells.

If you have a wireless doorbell than you may want to check the batteries. If it is hardwired it could be some failing electronics, try replacing the outdoor fixture first, just don't shock yourself. Turn off the breaker.

Depending on how your doorbell-chime is designed/manufactured: "Humming" can be caused by a "mechanically-loose" transformer; or by "electrical-noise" caused by improper-grounding/lack-of-sufficient-electrical-shielding/component-failure(s) in an audio-amplifier circuit.

There are two common reasons for a doorbell to be humming. A button could be stuck in the on position or some wires may be shorted together somewhere within the run between the doorbell and the buttons.
