If you want to change your doorbell or fix some issues, you must turn off its circuit breaker. But like any electrical work, it can be risky and difficult to find the breaker and turn it off.

So are you having trouble finding a doorbell breaker? Don’t worry, I’ve got you covered!

In this blog post, I’ll be sharing some easy tricks that can help you find a doorbell breaker within a short time. So let’s get started and get your house buzzing again!

What is a Doorbell Breaker?

Doorbell breakers aren’t that different from usual circuit breakers. These are a special type of circuit breaker to protect a doorbell’s electrical circuit, wiring, and electrical components from damage.

The main difference between a doorbell breaker and other breakers is that doorbell breakers support a lower voltage than the others. This is obvious since the electrical load for a doorbell system is typically much smaller than other household circuits.

You can find these breakers are located in the electrical panel just like any other circuit breaker. If there is only one breaker box for your whole house, you may find it there.

However, not all doorbells have a dedicated circuit breaker as you’ll learn soon.

Does a Doorbell Have a Breaker?

In general, a doorbell doesn’t have a dedicated circuit breaker. Instead, they are wired with other receptacles, electric boxes, light switches, or junction boxes.

Doorbells are low-voltage devices. They contain very low and intermittent loads.

A doorbell has three parts.

  • A step-down transformer
  • Chime box
  • And the doorbell itself

The transformer converts the incoming 120 V AC voltage into 16-24 V DC voltage. So the voltage used by a doorbell remains lower than the OSHA (Occupational Safety and Health Act) 50 V hazardous voltage level.

This is the reason electric technicians can work on a doorbell circuit live without turning off the breaker.

But it is always good to have a separate circuit breaker for your doorbell.

Having a dedicated circuit breaker helps to ensure that the doorbell system is protected from electrical issues that may occur on other circuits in the home. Moreover, it allows for easy maintenance and troubleshooting, since it is easier to isolate and identify problems with the doorbell system.

How To Figure Out Which Breaker Goes To The Doorbell

If you’re not familiar with electrical wiring, then this may be difficult for you. But usually, it’s the breaker that is closest to the doorbell chime or transformer.

Sometimes, the doorbell circuit will be labeled as so. This is the easiest way to figure out that this circuit breaks the doorbell. If none of the breakers are labeled, then there are some other ways to find out.

Go to the closest circuit breakers near the chime box. You can use a Circuit Breaker Finder to search for the correct breaker. Plug the outlet tester into a nearby receptacle.

Scan the breaker panel using the receiver probe. If you find the correct breaker, the light will start flashing faster. The beeping will also increase.

Finding the Doorbell Breaker

Now that you have some idea about doorbell breakers and how they work, it’s time to see the different ways you can find a doorbell breaker.

Method #1: Trial and error

This method is straightforward but time-consuming. For using this method, you will need some safety gloves and another person to check on the doorbell.

The idea is simple. You go to the circuit breaker panel. Then start switching off each breaker.

After turning off each, you ask the other person in front of the doorbell to try and press the doorbell. If the doorbell rings then this isn’t the doorbell breaker.

If the doorbell stops working, then this means that the last breaker you turned off was the doorbell breaker.

This is more like a brute-force approach. So you are guaranteed to find the doorbell breaker in this way. However, as mentioned above, you will need to go through every circuit breaker panel and circuit breaker to find the correct one.

You also require assistance from someone else. So if you’re alone, this process becomes even more tedious.

Moreover, this is applicable where other electrical connections don’t matter for the moment.

What we mean is that, if someone else is using any electronic device and you accidentally trip its circuit breaker, it will annoy him. So let everyone know before you do any kind of electrical work.

Method #2: Follow the wiring

To find the doorbell breaker by tracing the doorbell’s wiring path, you will need to locate the doorbell transformer and follow the wiring back to the electrical panel or breaker box.

Follow electrical wiring

Here is a step-by-step guide on how to do this:

  • Find the doorbell transformer. It’s a small box-shaped device. You can find it near the doorbell itself. But there’s a possibility that it’s located in the attic, basement, or utility room.
  •  Now search for the wiring that connects the doorbell transformer to the doorbell. It will typically be a pair of low-voltage wires. They will be connected to the doorbell and the transformer.
  •  Next, trace the wiring back to the electrical panel or breaker box. It will typically be routed through walls, ceilings, or floors. It may also be hidden behind insulation or other materials.
  •  After reaching the electrical panel, try to find the circuit breaker that controls the doorbell circuit. If you’re lucky, you may end up finding a label indicating that this is the doorbell breaker.
  •  If your circuit breaker fails to find a label, you can try turning off each circuit breaker one at a time until the doorbell stops working, as shown above. This will help you determine which circuit breaker controls the doorbell.
  •  You may also use a Circuit breaker finder to find the right breaker.

This method is more efficient than the first one because it reduces the number of breakers you need to work with. But that depends on the way your doorbell was wired.

If the doorbell was connected using exposed wires, then this becomes easier to follow. But hidden wires are not that easy to trace.

Don’t forget that the doorbell system may also be connected to other electrical systems in the home, such as security systems or intercom systems, which may require circuit breakers as well. In this case, you may need to follow the same process to determine which circuit breaker controls these systems.

Always be cautious when tracing the wiring path of the doorbell system. Electrical wiring can be dangerous, and it is important to use safety precautions and good judgment when working with it.

If you are unsure about how to safely trace the wiring path of the doorbell system, it is recommended to consult a licensed electrician for assistance. This brings us to the third method. And that is –

Method #3: Hire an electrician

This is the safest and least time-consuming method. If you don’t want to risk anything of your house and yourself or you don’t know how to deal with electrical components, then it’s your best choice to call an expert.

If possible, reach out to the same electrician who did the doorbell system of your house. If you can’t find him, reach out to the support of the manufacturing company of your doorbell.

If that’s not possible either, then just call an expert electrician. Of course, this method is not cost-effective at all. You will need to pay a good amount of fee or service charge. But if safety is your top priority then it’s worth the cost.

Will the Doorbell Still Ring if the Breaker is Off?

If the doorbell circuit breaker is turned off, the doorbell will not be able to operate. The doorbell system relies on a constant flow of electrical current to function.

If the circuit breaker is turned off, this flow of current will be interrupted. As a result, the doorbell will not be able to ring.

Ensure that if the doorbell circuit breaker trips or becomes faulty, it may cause the doorbell to stop working even if the breaker is still in the “on” position.

In this case, you may need to reset the breaker or have it replaced to restore the doorbell system to proper functioning.

How To Turn Off The Doorbell Breaker?

This is pretty easy once you locate the right breaker. Like any tripping switch, you pull it up and down to turn it on and off, respectively.

If you’re looking for a way to power off the doorbell instead of turning off its breaker, then there are a few more methods.

If you’re able to find the doorbell transformer, then removing it is sufficient. You can cut and cap off the wires or just unscrew the transformer.


This article shows you the various methods of finding a doorbell breaker. Each method has its pros and cons. You should choose the method that fits your needs the most.
