Flickering lights can feel like a small annoyance — until they start happening often. While sometimes the fix is simple, frequent flickering can also point to real electrical problems that shouldn’t be ignored.
At KMT Electric, we help homeowners across Central Columbus keep their homes safe and powered properly. Here are the most common reasons lights flicker — and what to do next.
This is the easiest issue to fix. If a bulb isn’t fully tightened, it can lose connection and flicker.
✔ Turn off the switch
✔ Let the bulb cool
✔ Tighten it carefully
If the flicker stops, you’re good to go.
Older dimmer switches aren’t always compatible with LED bulbs. Bad switches can also cause intermittent power.
If you hear buzzing or crackling, call a licensed electrician right away.
If lights flicker when:
You turn on the microwave
The AC kicks on
You plug in a vacuum
Your electrical system may be overloaded.
This is especially common in older homes that weren’t built for today’s electronics.
Loose wiring is one of the most dangerous causes of flickering lights. It can lead to overheating — and in severe cases, fires.
Warning signs include:
Burning smell
Warm outlets
Tripping breakers
Scorch marks
Don’t wait on this one.
Sometimes the problem isn’t inside your home at all. If your neighbors also notice flickering, it may be coming from the power supply.
Your electrician can help diagnose what’s happening.
Call KMT Electric if:
Flickering happens in multiple rooms
Your breaker trips often
You see sparks or smell burning
Outlets feel hot
You live in an older home
