Lights Flickering in the House? Common Causes and What to Do

Flickering lights can be a simple bulb or switch issue, but they can also signal a loose connection or a circuit problem. The key is figuring out whether it’s isolated to one fixture or happening across multiple rooms.

What Homeowners Usually Notice

  • Lights flicker when an appliance turns on (microwave, vacuum, HVAC)
  • Only one room or one fixture flickers
  • LED lights flicker on a dimmer switch
  • Flickering happens randomly, even when nothing changes

Safe Things You Can Check

  • Try a new bulb (especially if it’s LED)
  • If the light is on a dimmer, confirm the dimmer is LED-compatible
  • Tighten the bulb gently (power off if the fixture runs hot)
  • Note whether flickering is isolated to one fixture or multiple rooms

When It’s Time to Call a Professional

  • Multiple rooms flicker or dim at the same time
  • You hear buzzing, crackling, or notice burning smells
  • Lights flicker along with outlets acting up
  • The problem is getting worse over time

How This Is Usually Fixed

  • Replacing a failing switch or dimmer (especially older dimmers with LEDs)
  • Correcting loose wiring connections at a switch, fixture, or junction box
  • Balancing loads on the circuit or addressing an overloaded circuit
  • Diagnosing panel, neutral, or service connection issues if flicker is widespread
