Lights are flickering
Safety first
- Smoke, sparks, burning smell? Leave; call 911 outside.
- Avoid hot, buzzing, or damaged switches and outlets.
- Several rooms affected? Stop troubleshooting; call your electric utility now.
Fix it nowSeven steps
- Check for danger signs above before touching anything.Flickering can warn of an electrical hazard.
- Observe whether one lamp or several rooms are affected.Several affected rooms need utility assessment, not bulb troubleshooting.
- Limit DIY to one accessible plug-in lamp without danger signs.Leave fixed fixtures, switches, and wiring to an electrician.
The other four steps
- Unplug the lamp by its plug, with dry hands; let its bulb cool.Disconnect power before handling the bulb.
- Gently seat the bulb; never force it or touch socket contacts.A loose bulb connection can cause flickering.
- If needed, replace it with a bulb matching the lamp’s rating and compatibility.LED bulbs must match the dimmer’s compatibility requirements.
- Reconnect and test once; if flickering continues, unplug and call an electrician.Persistent flickering needs professional inspection.
When to stop
Stop and get a electrician if:
- Smoke, sparks, or burning odor: leave immediately; call 911 outside.
- Several rooms flicker, become unusually bright or dim, or lose power: call your electric utility now.
- Buzzing, crackling, discoloration, or hot outlets/switches: avoid touching; call an electrician now.
- Flickering continues after the bulb check: stop using that lamp; call an electrician.
- Breakers trip repeatedly: do not keep resetting them; call an electrician now.
