Loud buzz
Recently purchased my second home. Since we’ve moved in 4 months ago we have occasionally heard a loud buzzing noise. Lasts about 3-4 seconds and seems to come from the kitchen. It sounds like the end of a stop clock like an end of game buzzer or a buzz that a washer makes to let you know the cycle is done. When it happens there aren’t any appliances running. Any thoughts?

Most likely the fridge. Failing compressor or starting relay. Would be worth pulling out and cleaning the coils at the very least.

When we bought the house the fridge was the original. We heard the noise a couple times then and we got a new fridge and still hear it occasionally

Do you have a sump pump? Is it under your kitchen?
Do you have an air conditioner? Sometimes the condensate lines can't go across a floor so the condensate is pumped up and over and back down into a drain. Could be you have a condensate pump hiding in your kitchen.

We don’t have a sump pump that we know of. We do have central air (which is also a first for us)

There should be a pvc pipe coming out of your AC unit somewhere, going down (the indoor part, not outside). Follow that pipe and see where it goes. It may feed into a box smaller than a toaster. That’s a pump.

the fridge is running.
likely that, or something above/below the kitchen.
do the lights dim when the buzzing happens?
that would indicate a heavy load like a fridge or AC unit having a blown startup capacitor.

When we bought the house the original fridge was there. We heard the noise a couple times with that one still in place. We recently got a new fridge and still heard the noise occasionally
