The loud buzzing or clicking sound can be incredibly disruptive, not to mention annoying.

Whether it’s a noisy surge protector in your home office or a loud surge protector causing a disturbance at a venue, I’ve got you covered. 😁

I will provide the necessary steps to fix the loud noise from your surge protector and restore peace in your home or office.

Understanding Surge Protector Noise

Before we delve into the solutions for troubleshooting a noisy surge protector, let’s take a moment to understand why it happens.

Surge protectors safeguard electrical devices from power surges and voltage spikes.

When such surges happen, surge protectors divert excess current away from our connected devices, which can result in audible clicking or buzzing sounds.

This sound is a natural part of the surge protector’s functionality and indicates that it is working to keep our devices safe.

But, if the noise becomes too much or constant, it could signal an issue that needs attention.

5 Common Causes of Noisy Surge Protectors

Surge protector making loud noise could be due to several common causes:

Understanding these causes will help you troubleshoot and resolve the noise problem.

Here are the main reasons why surge protectors might be noisy:



Voltage spikes Electrical issues such as voltage spikes can lead to noisy surge protectors. When a voltage spike occurs, the surge protector diverts excess current away from connected devices, resulting in a clicking or buzzing noise.
Faulty wiring Poor or faulty wiring can also contribute to surge protector noise. If the wiring is not properly insulated or grounded, it can cause disruptions in the electrical flow and result in audible noise.
Short circuits Short circuits within the surge protector or connected devices can cause loud noises. A short circuit occurs when there is a direct connection between electrical components that should not be connected, creating excessive current flow and generating noise.
Power-hungry devices Power-hungry devices or appliances that draw a large amount of electrical current can put additional strain on the surge protector, leading to audible noise. These devices may require more power than the surge protector can handle.
Lightning strikes In rare cases, lightning strikes can cause loud noises and potential damage to the surge protector. The high voltage from a lightning strike can overload the surge protector, resulting in noise and potentially rendering the device ineffective.

With these common causes, you can take the necessary steps to troubleshoot and resolve the noise problem in your surge protector.
