• Intermittent or Constant: Determine if the flickering is intermittent or constant. Intermittent flickering can be harder to diagnose because it happens sporadically, while constant flickering might indicate a more consistent issue.
• Affected Area: Note whether it’s happening in a single room or throughout the house. This can help you determine whether it’s a localized problem with the main power supply.

• Type of Bulbs: Identify the types of bulbs that are flickering. Due to their energy-saving characteristics, LED and fluorescent lights are more prone to flickering than incandescent bulbs.
• Bulb Tightness: Ensure the bulbs are screwed in tightly. Loose bulbs can cause flickering due to an inconsistent connection.
• Compatibility: For LED lights, check if your dimmer switches are compatible. Not all dimmers work well with LEDs, leading to flickering.

• Loose Fixtures: Check for any loose wires or connections in the fixture. A loose wire can cause intermittent flickering and is a fire hazard.
• Dimmer Switches: If your lights are connected to a dimmer switch, the issue might lie within the switch. Try replacing it with a new one that’s compatible with your bulbs.

• Large Appliances: Large appliances, like air conditioners or refrigerators, can cause lights to flicker when they power on. This is due to the sudden spike in electrical demand.
• Circuit Overload: If flickering occurs when multiple appliances are running, your circuit might be overloaded. Consider redistributing the electrical load or upgrading your electrical panel.

• Voltage Fluctuations: Fluctuations in your home’s voltage can cause flickering. A multimeter can help you check for stable voltage levels.
• Service Connection: Inspect the service mast, meter base, and service panel for any signs of damage or wear. Loose service conductors can cause flickering throughout the house.

If, after going through these steps, the problem persists or you’re unsure about dealing with electrical components:

• Hire an Electrician: A licensed electrician can safely diagnose and fix issues related to your home’s electrical wiring, from simple fixes to more complex problems like updating the electrical panel.
