Most doorbells can last years; however, the majority of electrical devices will eventually fall victim to malfunction. Whether your doorbell doesn’t ring, makes strange noises, or rings continuously, it’s usually a simple fix. That being said, you should always call a professional electrician to handle any electrical work in your home. At Harrison Electric, we stress the importance of experienced and professional electrical work, both for your safety and the functionality of your home. If you’ve noticed your doorbell isn’t working properly, below are five of the most common reasons why.
1. Disconnected or Loosened Circuit Wiring
Your doorbell consists of a push button, a wall chime, and a transformer. Various wires connect these components, and occasionally, these wires may become loose or disconnected. Perhaps the wires that connect to your outdoor push button have disconnected, or maybe those connecting the chime to the transformer have loosened. Either way, this issue will cause your doorbell to stop ringing.
2. Chime or Speaker Malfunction
The sound your doorbell emits comes from a small chime or speaker box located inside your home. Occasionally, the wiring inside the chime may malfunction, causing your doorbell to cease making sounds. To determine if your chime is the issue, a multimeter is necessary. This tool will test the chime’s wiring to discover whether or not a current is flowing to it. Always call a professional electrician to perform current testing as it can present a hazard to an untrained person.
3. Transformer Voltage Issue
A doorbell transformer works to step down higher-voltage electrical power to lower-voltage electrical power. Since your doorbell only requires about 10 to 20 volts, it requires a transformer to function properly. Sometimes, however, the transformer may be faulty, which causes the doorbell to malfunction. To determine if the transformer is the source of the problem, a professional electrician is necessary. A trained professional can test the terminals within the transformer using a tool known as a voltmeter. If they do not match the voltage marked on the transformer, you’ll need purchase a replacement.
4. Disconnected Button Wires
In many cases, a malfunctioning doorbell is due to disconnected wires behind the doorbell button. There are two wires behind the outdoor button, and occasionally, they may become loose or disconnected. A professional electrician can test the two wires to determine if they create sound when they are touched together. If not, it’s likely that there’s a disconnection somewhere. If the wires do create sound when they make contact, you likely have a broken doorbell button and will need to purchase a replacement.
5. Tripped Circuit
Perhaps the simplest fix for a malfunctioning doorbell is resetting the circuit. Your doorbell doesn’t require a dedicated circuit, so it will typically share one with several other electrical devices. If you notice that other devices in your home have also ceased working, try resetting the circuit to determine if that’s the problem.
