Check for Power with a Voltage Tester
Using a non-contact voltage tester helps verify if power is reaching your fixture or outlet. When I tested my flickering living room light, I found it sporadically losing voltage due to a worn-out connector. If there’s no power, the problem might be upstream—like a blown breaker or a disconnected wire. Make sure all relevant switches are turned on, and inspect your breaker panel for tripped switches. This step is crucial before proceeding further.
Inspect the Switch or Fixture Connections
Loose or damaged connections are common culprits. Remove the switch or fixture again and gently tug on the wires—if they come loose, tighten or replace them. In one instance, a connector screw had rusted, causing intermittent flickering. Don’t forget to confirm the wires are properly secured under their terminals. For a safe and professional approach, consider consulting [electrician troubleshooting tips](https://reliableelectricpro.com/troubleshooting-electrician-expert-tips-for-lighting-ev-chargers) to avoid common pitfalls.
