why doorbell not ringing but lit up

Has your doorbell been causing you problems lately, like your doorbell ringing on its own? A faulty doorbell could create chaos as you might miss out on people visiting home, and any courier or parcels you may expect could get returned, making it a nightmare for no reason.

If your doorbell was working just fine, then there could have been some recent changes that may have caused it to stop working. You might be surprised at how easily you can fix minor issues that may be causing problems with your doorbell.

Especially if the light continues to light up but the bell sound is malfunctioning.

If you don’t want people to resort to knocking on your door incessantly, it might be better to fix your doorbell issues as soon as possible.

So, before you go on and call professional help or replace your bell or chime box, there are a few things you can do to check your bell.

The following reasons would be attributed to a bell that’s stopped working.

1. The Button has Stopped Working

The Button has Stopped Working

In most cases, it is observed that a faulty button, old button, or worn-out button could be the cause of a bell not working. The wires at the back of the button fail to relay the electrical signals, which may be causing issues.

Here’s how the bell works: every time someone presses the bell, a circuit of electrical connection is formed, and the bell rings. However, when there is an issue with the button’s wiring, it causes a glitch in the circuit, and hence, the bell does not ring, despite the fact that the bell is actually working just fine.

Even within this issue, check if it’s just the button that’s a presenting issue or the wiring. Based on that, decide if you can change the button or the button’s wiring.

2. Bell Box

Bell Box

Once you know that your button isn’t the source of the problem, it’s time to investigate further. For this, you need to check the chime unit or the bell box. Here, you need to first remove the cover and undertake a thorough check.

This includes checking for any loose wiring, corroded wires, damaged wires, exposed electrical connections, or such. If you don’t see any obvious issues at this stage, it’s advised to use a voltage tester to check out the voltage of the connections.

Generally, also check if the system is clean and there is no dirt or dust in this part of the bell unit. You will be surprised at how dirt, dust, and debris could be the reason behind a faulty electric line. If none of the above seem to be working, it might be best to get the bell box replaced.

3. Check The Transformer

Check The Transformer

Transformers are an important part of the bell’s functioning apparatus. If you have checked the basics of the button and the bell unit, it may be time to look at the transformer and check if this is where the issue lies. For this, you have to be aware that the transformer holds a higher voltage.

Therefore, it is not advisable to check using the low voltage tester.

However some low-voltage testers may let you test the transformer; however, if you are unable to do so, it is recommended to call a professional for help. Do not try to handle high voltage powers by yourself, especially if you do not have the prior expertise and expertise for it.

4. Wiring Check

Wiring Check

Now that all the major parts of your bell apparatus have been checked, i.e., the transformer, the button, and the bell unit, it’s time to focus on the wiring. Wiring forms the lifeline of any electrical apparatus.

These are responsible for passing the electricity from one part of the bell apparatus to another. For your doorbell system to be working well, you must ensure that your bell wirings are all working perfectly well.

First, check the condition of the wires. Are they worn down, are they out of shape, dirty, or just need a replacement? Even small issues with the wiring can overthrow the functioning of the entire apparatus. If you notice wiring issues, note that you will need professional help and assistance in sorting it out. Do not try to manage the wiring issues yourself.


A doorbell is an important part of every home. The small little chimes, or the ring of the doorbell, is a signal for you to attend to those waiting on your doorstep. While these days, there are various wireless bells and digital doorbells, you can still get your old doorbell checked before completely replacing it.

A simple measure to check why your doorbell isn’t ringing despite lighting up could be due to faulty wiring, a chime box, a button, or a transformer. Use the simple techniques stated above to undertake a quick check of your housebell.

If you still cannot find out the issues, or if it is beyond your purview of expertise, it may be time to call in expert professional help.

Frequently Asked Questions

Why Can’t I Hear My Doorbell Ring?

Faulty wiring is generally a prominent issue that could be the reason why your doorbell isn’t ringing. You can check if there is any loose wiring on the button, transformer, or chime box. Once that is eliminated and the problem persists, try a voltage tester to figure out if the electricity is passing through properly.

What Makes the Doorbell Light Up?

Every doorbell is nothing more than a proper, simple circuit. This circuit runs a low voltage transformer that reduces 120V AC to 21 V AC, and thus the bell rings. A small incandescent bulb is wired across to give an indicator of a well-functioning bell network.
