Just today, I noticed probably a half dozen GFIs around my house are buzzing. I am pretty sure it just started, since some are a bit loud.

I know some of these are on different circuits, and not every GFI in the house is doing this. Some buzz, some don't.

No recent electrical changes.

I cut power to house for 30 seconds to see if that would reset things and take away buzzing. It did not.

GFIs buzz even if I hit the test button. So hot or not they buzz. Then when I push in reset button, they still buzz.

Normal outlets connected to GFI outlets do not buzz.

Any idea what this could be? It is kind of freaking me out.

Haven't run into this myself. You could try changing them for another brand.
Maybe try changing one and see what happens.

There's a brand that has an especially bad reputation called
something like "Pro Electric". If you have those it's all the more
reason to change them.

Odd they would act up at the same time, I would have at least checked the incoming voltage with a real Volt / OHM meter.
Noticed the lights getting brighter then dimming?
A loose neutral can cause all kinds of electrical issues.

A GFI does not even need a ground to work, so I doubt that's the issue.

I don't know if it's dangerous but I spoke to a retired electrician & he said to check the 2 grounds in the panel & the ground on the water main. He also said to check the voltage on both hot legs.

Nope, no changes in the lights.

Google searched and found no hits on this kind of issue.

I am going to see if it goes away, or gets worse. Probably have electrician come out in either case...

Thanks, I'll take a look...
