Of course, when the voltage occurs, the circuit should be turned on, but if you replace any of the parts (transformer, bell, doorbell button, doorbell cable) the circuit must be turned off. Even a 12 volt short can cause a fire and you never know that something is wrong with a 120 volt cable.

What causes a transformer to hum?
WHAT MAKES A TRANSFORMER HUM? Transformer noise is caused by a phe- nomenon called magnetostriction. In very simple terms this means that if a piece of magnetic sheet steel is mag- netized it will extend itself. When the magnetization is taken away, it goes back to its original condition.
What causes a transformer to burn out?
As others have mentioned, the transformer is burning up because the load on it is too great. This is likely caused by a damaged component within the control circuit, which is drawing far too much current for the transformer. … Like all electrical devices faults also happen in the transformers which cause failures [1].
What happens when a transformer fails?
One failure can cause many problems. A simple fault at the distributing end can cause black-out of power to the whole area. The fault can also be very dangerous as the transformers contain large quantity of oil in direct contact with high voltage components.
Who is the bad transformer?
The Decepticons are the main antagonists in the fictional universes of the Transformers multimedia franchise. They are depicted as a faction of sentient robotic lifeforms led by Megatron, identified by a purple face-like insignia.
How do I stop my transformer humming?

You can reduce some of the noise generated by an electrical transformer by using materials that prevent the sound from spreading. Covering the walls of the transformer room with absorbent materials such as kimsul, acoustical tile or fiberglass may help keep the noise contained.
Why is my doorbell box humming?
If your doorbell is relentlessly buzzing or humming, the button may be stuck in the contact position. … You will need to immediately disconnect the button from its low-voltage wires. Otherwise the transformer (or bell unit) will burn out and you will have to replace it.
How do you cover a doorbell transformer?

Can I use a 24V transformer on a 16V doorbell?
A common voltage required by doorbells is 16V. … Usually, doorbells are designed to support 20% more or less of the required voltage. But still, this does not make up for the 16V using a 24V transformer. While you can still use the 24V transformer, it isn’t really safe to do so.
Can a transformer be outside?

What would happen if a transformer is connected to a DC supply?
When you connect to DC, transformer core gets saturated, heavy current flows results in damage of winding. Hello, The DC supply will be definitely damaged (when there is no protection scheme) due to nearly zero resistance of the primary winding.
Why would a transformer not work?
As mentioned before, transformers do not allow DC input to flow through. This is known as DC isolation. This is because a change in current cannot be generated by DC; meaning that there is no changing magnetic field to induce a voltage across the secondary component.
