Common wiring issues with ring doorbells
How wiring problems can cause buzzing in your Ring doorbell
If your Ring doorbell or chime is only making a buzzing sound, wiring issues are often to blame. Whether you have a wired doorbell, a smart doorbell, or a video doorbell, the way wires are connected inside your doorbell system can affect how your chime and doorbell unit work.- Loose or frayed wires: Over time, wires can become loose or damaged, leading to poor electrical contact. This can cause your chime to buzz instead of producing a clear sound.
- Incorrect wiring: If the wires are not connected to the correct terminals on your doorbell button, chime, or transformer, the system may not get enough power, resulting in a buzzing sound.
- Old or incompatible chime: Traditional chimes may not be compatible with smart doorbells or wireless doorbells, especially if a chime connector is not used. This can cause issues with the sound coming from your doorbell chime.
- Wiring for wireless devices: Even some wireless doorbells require proper wiring for the chime or transformer. If these are not set up correctly, you may hear a buzzing sound instead of a ring.
What to check in your doorbell wiring
When troubleshooting a buzzing sound, start by turning off the power to your doorbell system at the breaker. Then, check the following:- Are all wires connected securely to the doorbell button, chime, and transformer?
- Is there any corrosion or damage on the wires?
- Are the wires connected to the correct terminals?
- Is your chime compatible with your Ring video doorbell or smart doorbell?
Power supply and transformer concerns
Checking Your Doorbell Power and Transformer
One of the most common reasons for a buzzing sound from your doorbell or chime is an issue with the power supply or transformer. Ring doorbells, like many smart doorbells, require a specific voltage to operate correctly. If the voltage is too low or unstable, your wired doorbell may only buzz instead of producing the expected sound.
- Voltage Requirements: Most Ring video doorbells need a transformer that supplies between 16-24V AC. If your existing doorbell transformer is below this range, the doorbell unit might not function properly, leading to a buzzing sound or no sound coming from the chime.
- Wired vs. Wireless Doorbells: Wired doorbells rely on a consistent electrical supply, while wireless doorbells use batteries or plug-in power. If you have a wired doorbell, check that the wires connected to the transformer are secure and not corroded. For wireless devices, ensure the batteries are charged or the power adapter is working.
- Transformer Age: Older transformers can degrade over time, causing inconsistent power delivery. This can result in your doorbell only buzzing or the chime not working as expected.
- Multiple Devices: If you have added several smart devices or video doorbells to your doorbell system, your transformer may be overloaded. This can cause buzzing or other power-related issues.
To troubleshoot, use a multimeter to check the voltage at the doorbell button and at the chime connector. If the voltage is outside the recommended range, replacing the transformer may resolve the issue. Always ensure power is off before handling electrical components.

Compatibility between traditional chimes and ring doorbell
How Smart Doorbells Work with Traditional Chimes
Many homeowners want to keep their existing doorbell chime when upgrading to a smart doorbell like the Ring. However, not all traditional chimes are compatible with modern video doorbells. Understanding how these devices interact is crucial for troubleshooting a buzzing sound or a chime that doesn’t ring properly.
- Mechanical vs. Digital Chimes: Most wired Ring doorbells are designed to work with mechanical chimes, which use physical parts to create sound. Digital chimes, which play electronic tones, often require a special chime connector or may not be compatible at all.
- Wireless Doorbells: Wireless doorbells and chimes operate differently from wired systems. If you have a wireless chime, it may not work with a wired smart doorbell unless you use a compatible wireless receiver or bridge.
- Chime Connector: Some Ring models need a chime connector to ensure the doorbell unit and chime communicate correctly. Without it, you might hear only a buzzing sound or no sound coming from the chime.
What to Check for Compatibility
When troubleshooting a buzzing doorbell or a chime that doesn’t work, consider these steps:
- Verify if your doorbell system uses a mechanical or digital chime.
- Check if your smart doorbell model supports your chime type. The Ring website and user manual list compatible devices.
- Ensure all wires are connected securely between the doorbell button, transformer, and chime.
- If using a wireless doorbell, confirm that the receiver is compatible with smart doorbells.
- Look for any required accessories, like a chime connector, especially for digital chimes or advanced video doorbells.
Compatibility issues are a common cause of buzzing or non-functioning chimes in both wired and wireless doorbells. If you’ve checked the wiring and power supply but the buzzing sound persists, reviewing your chime’s compatibility with your Ring doorbell is an essential troubleshooting step.
