The problem of occasionally flickering lights is common and may not be dangerous. It often results from minor electrical problems that you can fix on your own. But if the problem continues, you may need to consult an expert to see if the cause of light flickering in your house is more serious.

This blog post provides vital information on possible causes of lights flickering in your house and how to fix this issue.

What Causes Lights to Flicker?

Here are possible reasons why your lights are flickering:

  1. Loose Bulbs: If you see a flickering light bulb, the chances are that the bulb is loose in its socket. This is especially true if you’re using a lamp plugged into a wall outlet. The light bulb may not make a secure connection to the socket if not installed properly. This could lead to it flickering on and off intermittently. Simply tightening the bulb which is flashing should take care of the issue. Don’t forget to switch off the bulb and wear hand gloves before tightening it into its socket..
  2. Loose or Worn Out Electrical Wiring: One of the leading causes of flickering, loose electrical wiring is a very serious electrical issue which can even lead to house fires. You may be surprised to know, but according to a March’2019 report of NFPA, approximately 70% of home fires are caused by wiring-related faults. So, check the wire connections and look for signs of loose wiring. If you notice even a slight problem of loose wiring, call an electrician or an electric company to get a thorough inspection done..
  3. Old Wiring, Breakers, Connectors, and Switches: If your home is equipped with old wiring, breakers, connectors, and switches, these can cause the lights to flicker. This is especially true if the wiring is outdated or the breakers, connectors, and switches are loose or worn out. In any case, it is good to get the electrical wiring and fixtures at home replaced periodically to reduce the risk of electrical hazards..
  4. Overextension: Lights flickering in houses may also be due to overextension. If the lights start to flicker every time you plug in a heavy appliance, such as a microwave, a water heater, or a washing machine, your home may not be equipped to handle heavy electrical loads. Your electrician will check the electrical system and suggest repair and installation solutions accordingly..
  5. Electrical Arcing: Arcing is a dangerous electrical problem that can cause lighting issues, intense heat, and even electrical fires and shocks. It happens when the circuit is broken, and the electrical current passes through the air instead of a conductor. That’s why it’s important to be aware of this issue and take appropriate measures to prevent it. Not only could it cause property damage, but it could also put your safety at risk..
  6. Heavy Electrical Usage of Your Neighbour: If you’re living in an apartment or condo, flickering lights in your home can be a sign that your neighbour is using a lot of electricity. Because the electrical system is shared between units, you must talk to your neighbour and let them know if you’re experiencing this issue. It can be uncomfortable to bring up this kind of conversation, but it’s critical to discuss it to resolve the issue..
  7. Power Company Issues: Did you notice your lights flickering after a power outage? It could be an issue with the power company. They may be trying to fix a fault in the line that’s causing your lights to flicker. If that’s the case, it’s best to contact them and let them know about the issue. They’ll be able to help you get your lights back to normal in no time.

How to Fix Flickering Lights?

Flickering lights is a common issue that can be fairly straightforward to fix. Here are some practical ways to help you troubleshoot and get your lights working again.

  1. Check for Loose Bulbs: Check to see if the cause of the lights flickering in the house is loose bulbs or loose connections. If a bulb is not screwed in completely, the socket isn’t able to make contact with the bulb properly. And this can result in electrical light flickering or a flickering light bulb. If you have fluorescent light bulbs, they may flicker in cold weather and as they power. And that’s really nothing to worry about.
  2. Check for Faulty Light Switches: Flickering light or a flickering bulb can also be the result of faulty light switches that may not be connected to the bulb. So, to check if that’s the reason, turn the wall switch off and back on to see if the lights stop flickering. If that doesn’t work, let it stay off for a couple of hours. If it doesn’t work either, you may probably have to change the switch. But changing switches without electrical safety may result in an electrical fault or a severe electric shock. So, make sure you know how to do it before you take on the task. In any case, calling an electrician is advised.
  3. Replace Old Wiring, Breakers, Connectors, and Switches: If your home is older, it’s possible that its wiring and other components may be outdated and not able to handle the electrical load. If you’re comfortable with it, you can replace the old wiring, breakers, connectors, and switches with new ones. It’s a great way to ensure you get the most out of your electrical system and keep your home safe.
  4. Check for Voltage Fluctuation: Light dimming or light flickering can also be the result of fluctuation in voltage due to inconsistent power supply. When you plug in an appliance with high wattage while the voltage is fluctuating, lights may start to flicker. If that happens, turn the appliance off immediately to reduce some load. But if the lights continue flickering, turn all the lights, and electrical appliances off till the voltage is normal again. The problem of fluctuating voltage should not be overlooked. If the lights flicker or dim frequently, you should get a power supply box or the circuit breaker checked by a professional. If not taken seriously, it can damage electrical appliances.
  5. Updated the Wiring System if Any Large Appliances are Running: It is also possible that you are operating heavy-duty appliances, causing the Issue. For instance, if you have large appliances, like a refrigerator or washing machine, running simultaneously as the lights are flickering. In that case, your wiring system needs to be updated.
    This is because your existing wiring system is not capable of handling the load of these large appliances. Again, you’ll need to contact a licensed electrician to take a look.

It is advised not to deal with these complex electrical problems on your own because they can result in devastating electrical accidents such as electrical fires. Consult your electrician and get the issue fixed safely.
