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

Below, we have discussed how to go about electrical repair when lights flicker. Read on.

How to fix flickering lights?

Usually, the lights may flicker due to small electrical or lighting issues that can be fixed with simple home repair tricks. Here are a few things you can do:

  1. Check for Loose Bulbs

    Check to see if the cause of 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 connecting with 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. 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 voltage is normal again.

    The problem of fluctuating voltage should not be overlooked. If the lights flicker or dim frequently, you should get power supply box or the circuit breaker checked by a professional. If not taken seriously, it can damage electrical appliances.

Cause of flickering light – Complex Electrical Issues

  1. 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. 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.
    In any case, it is good to get the electrical wiring at home replaced every 5 to 7 years to reduce the risk of electrical hazards.

  2. 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 electrical repair and installation solutions accordingly.

  3. Electrical Arcing

    Arcing is a dangerous electrical problem which can not only result in lighting issues but can also generate intense heat and become the cause of an electrical fire or shock. It happens when the circuit is broken, and the electrical current passes through the air despite it being non-conductive.

  4. 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.
