How to Troubleshoot Flickering House Lights


If you have noticed that your lights flicker or dim, this might be a sign that there is a serious electrical problem in your home. However, sometimes, it might be a simple issue that is fixable with just a minor tweak. Knowing how to troubleshoot flickering house lights will help you figure out when it is necessary to call in a professional and when it is something that you can fix on your own.

Check to see if the lights flicker when a large appliance turns on. Portable heaters, air conditioners and other electrical appliances that use a large amount of electricity pull your home's current. If your home's electrical system is not set up to handle this load, the lights will flicker. Call an electrician if this occurs.

Tighten the light bulbs in lamps. A loose connection with a bulb will cause a light to flicker. Turn off the lamp, let it cool, and then tighten the bulb.

Check electrical plugs to see if they are firmly seated in the outlet. A loose plug will cause lights to flicker.

Observe weather patterns in your area. A storm even a few miles away will cause your lights to flicker if the electrical company is having outages or problems. When in doubt, call your company's hotline to check to see if anyone else is experiencing difficulties.

Tips & Warnings

  • Never attempt to fix wiring on your own. This is extremely dangerous and can cause serious injury or even death.
