Suffering from flickering lights within your home can be more than just a nuisance. If this has been a recurring issue, it’s crucial to determine the cause. Checking your cords and outlets is a good starting point, but the underlying issue often lies elsewhere. Ensure safety first by turning off the main breaker before proceeding.

Upon powering down, it's time to inspect the electrical panel by removing its cover, which is typically secured by screws. A common culprit for flickering is a loose connection within the electrical circuit, often found at the circuit breakers. With the power off, use a flathead screwdriver to check each breaker's connection. Each breaker has a screw to secure the wire; these can become loose over time or may not have been sufficiently tightened during installation.

Here are key steps to address the issue:

  • Carefully examine the screws on each breaker without applying excessive force. The aim is for them to be snug, but not overtightened, which can cause damage.
  • Go through the entire panel, from the top breaker down, to check the tightness of each screw.
  • Take note of grounding bars found on either side of your panel. Ground wires and white wires are both connected here. While these screws are typically secure, a quick check is still recommended.
  • Ignore screws that don’t have wires connected; their tightness is not of concern.

Once all internal checks are completed, you'll then need to reattach the electrical panel cover. This can be a bit challenging as they can wobble. Loosely attach the top screws first to stabilize the cover, align the holes, then proceed to tighten all screws for a secure fit.

Finally, restore power by switching the main breaker back on. This entire process is relatively quick and can possibly resolve flickering issues. However, if you're not comfortable working on your electrical panel, or if the problem persists, consulting a professional electrician is highly recommended. Even if these adjustments don't solve the flickering, ensuring that your connections are secure is an important safety measure.
