ADT Doorbell Keeps Chiming: What To Do?

Last updated: April 3, 2023


If your ADT doorbell keeps chiming without any apparent reason, it can be both annoying and concerning. If the chimes continue without any specific trigger, it may be a sign of a larger issue. It is important to check the doorbell’s batteries and ensure it is securely mounted. The wiring may be faulty if the batteries have been recently replaced and the doorbell is adequately mounted.

If this is the case, it is important to contact an electrician or someone with knowledge of electrical wiring to help with the issue. Additionally, it is important to ensure that the doorbell is not receiving a false signal from another doorbell in the area, as this could be causing the constant chimes. The following troubleshooting steps can help you identify and resolve the issue with your ADT home security system.

1. Check For Motion Detection

Some ADT doorbell models can trigger a chime when motion is detected. Verify if the motion detection feature is enabled and the sensitivity is too high. Adjust the motion detection settings in the ADT app or the doorbell’s settings to prevent false alarms caused by passing cars, animals, or other environmental factors.

2. Inspect the Doorbell Button

A stuck or malfunctioning doorbell button can cause continuous chiming. Inspect the button to ensure it is not jammed or damaged. If necessary, gently clean the button with a soft, lint-free cloth to remove any dirt or debris causing it to stick.

3. Examine the Wiring

Loose or damaged wiring can cause intermittent or continuous chiming. Turn off the power to the doorbell at the circuit breaker and inspect the wiring. Ensure that all connections are secure and that there is no visible damage to the wires. If you’re unsure about working with electrical wiring, consider hiring a professional electrician to examine and repair the issue.

4. Check the Chime Settings

Verify the chime settings on your ADT doorbell and ensure they are configured correctly. Some doorbells have different chime modes, and an incorrect setting may cause unwanted chiming. Refer to your doorbell’s user manual for adjusting the chime settings. You can turn the door chime off and back on as well.

5. Reset Your ADT Doorbell

Resetting your ADT doorbell can resolve software-related issues that may be causing the continuous chiming. Disconnect the doorbell from its power source, wait 30 seconds, and reconnect it. Allow the doorbell to reboot and check if the problem is resolved. Remember that you may need to reconfigure your doorbell settings after a reset.

6. Update Firmware and ADT App

Ensure that your ADT doorbell is running the latest firmware version and that you’re using your smartphone’s most recent version of the ADT app. Outdated firmware or apps may cause compatibility issues and affect the doorbell’s performance.

7. Contact ADT Customer Support

If you’ve tried all the troubleshooting steps above and your ADT doorbell keeps chiming, it’s time to contact ADT customer support. They can provide further assistance, diagnose potential hardware issues, and guide you on the next steps, such as replacing or repairing.

8. Check for Interference

Wireless interference from other devices or networks in your area can sometimes cause issues with your ADT doorbell’s operation, including continuous chiming. Look for any nearby devices, such as Wi-Fi routers, cordless phones, or microwave ovens, that may be causing interference. If possible, move these devices further away from your doorbell or change their operating frequency/channel to minimize interference.

9. Replace the Doorbell Transformer

A faulty doorbell transformer may cause continuous chiming. The transformer reduces your home’s electrical voltage to a level suitable for the doorbell. If it’s not working correctly, it can cause erratic behavior, including unwanted chiming. Consult an electrician to inspect and replace the transformer if necessary.

10. Inspect Your Wi-Fi Connection

Your ADT doorbell relies on a stable Wi-Fi connection to function properly. A weak or intermittent connection can cause various issues, including continuous chiming. Check your Wi-Fi signal strength near the doorbell using a smartphone or a Wi-Fi analyzer app. If the signal is weak, consider relocating your Wi-Fi router or using a Wi-Fi extender to improve the signal strength.


If your ADT doorbell keeps chiming, there are several troubleshooting steps you can take to identify and resolve the problem. Checking for interference, inspecting the doorbell transformer, and verifying your Wi-Fi connection are additional steps that can help you address the issue. 

Always remember that if you’re unsure about working with electrical components, it’s best to consult a professional electrician for assistance. Don’t hesitate to contact ADT customer support if you need further help or guidance to ensure your doorbell functions properly and reliably.
