need some professional advice

so i found this sub Reddit just now in desperation. My family just constructed the this house we are in a year ago. At the very start the power would occasionally fluctuate every 15 minutes or so, causing lights to dim and fans to noticeably slow down. Then we noticed a correlation with our microwave being turn on having this same effect. We have ignored this problem up until today where now it fluctuating every two seconds , which really buts me on edge. What Do you guys think is causing it? Whom should i call to take a look? The power company or some electrician to look at the breaker box? im heading off to work now so i wont be able to answer any questions till 6 oclock. Thanks in advance.

I'd probably go with it being a dead microwave. If the microwave is unplugged does it still happen?

you caught be before i left for work. I know that other high drain operations such as the air conditioning causes the issue as well. since its not exclusive i don't think so. However i will try when i get back to see if it helps.

Well its always a good place to start, do a bit of troubleshooting flick things off and on till you can determine wether its appliance driven.

If not I suspect getting your local electrician out and they will advise you on your next move.

it still occurs on its own when I unplug the microwave and shut off the air conditioning. I can only create a predictable drop in power when they are running. edit: turns out i tell the difference in light brightening and dimming ,turns out that the voltages is increasing.

I would call the power company to check for loose connections on their end. Overhead service or underground?

I would definitely call the power company then. It's a loose neutral most likely, so since all the power coming in can't return back out on it then it back feeds to the other hot line feeding your house. It happens lots with overhead services. If it's not there then it's in the meter or panel, but that's what I'm most sure it is

hmm i realize im a idiot, the voltage increases from 115 volts to 128 volts when i kick on the micro wave.

the two second flickering has since stopped. so i have yet to catch the unaccounted fluctuations.

Check what voltages you're getting at the other outlets with the microwave/ac on and off

115 volts ideal 128 volts when running.

microwave on and dehumidifier off 133 volts

what/where should i be doing other tests, and how can i be more methodical? every device seems to have a significant effect.

Bad neutral issues from the service itself. Call your local utility and have them troubleshoot their end first (it's free) then call the guy who wired the home.

can you elaborate on what that means for me please?

A loose or poorly connector Neutral conductor will affect the flow of electricity in a way that creates voltage spikes, brown outs, bulbs dimming, and potentially a fire hazard.

You can call your power provider and explain the situation to them, they will(should) check that their connections are done properly for free and fix any issues on their side. If this doesn't correct the issue you'll need to contact an electrician to troubleshoot the home side of your panel.

thank you for taking the time to explain, I'm going to call them asap. I dint realize that it was such a potential hazard.
