Electrical appliances make noise, but it’s usually inaudible. Even if there are sounds coming from your devices, they rarely require immediate attention. But that’s not always the case. You might need to contact an electrician if the noise gets too loud. Many problems, such as faulty appliances and damaged wiring in your walls, can be the cause of this issue. Bringing in an expert is the best way to diagnose the problem, but you should first understand the potential causes of excessive electrical noise.
Faulty Electrical Panel
Electrical panels produce some noise, but you shouldn’t be able to pick it up from a couple of feet away. It usually indicates the panel is faulty and may need replacing.
You might hear noise coming from your walls. Typically, this indicates bad wiring connected to your switches or outlets. In most cases, the problem is caused by improper grounding, loose wires, or an overload. Each can be a major fire risk, so contact a professional right away. In the meantime, shut off electricity to the wiring to stay safe.
Electrical Arks of Circuit Overloads
If you can trace the buzzing or humming to the circuit breaker, turn off all circuits immediately and reach out to an electrician. You could be dealing with loose or damaged wires, causing the circuit to overload. It might also indicate electrical arcs. This is a dangerous form of electrical discharge that requires specialized tools and techniques. Therefore, don’t try to address the malfunction on your own – leave the work to an expert.
Inadequate Light Fixtures
Electrical noise regularly comes from light fixtures, which normally means you need to replace the light bulb. That’s especially the case if you have lights connected to dimmer switches. The easiest workaround is to swap out the bulbs for those designed for such switches.
However, call an electrician if you can still hear sounds after the replacement. It could point to a more serious issue.
- Alternative current causes magnetic fields to fluctuate, which causes vibrations but is usually not audible.
- If the buzz in your home is louder than normal, that could be something to worry about.
- If the sound is from an appliance, try unplugging it; if from the electrical panel, call an electrician.
“When the white noise becomes something more noticeable—and irritating—is when you should start to think about it.”
