Lights Flickering In House: 10 Reasons Explained with Solutions
Have you ever been in a room with the lights flickering? It’s an unnerving experience. You can’t help but feel anxious as if something isn’t right.
According to a study done by the National Fire Protection Association (NFPA), malfunctioning electrical work is the second leading cause of house fires.
Flickering lights in the home can be caused by faults in the electrical wiring, the type of bulb and their rating, or the appliance installed as part of the same electrical circuit. Changes in voltage and current flow brighten and dim light bulbs as they fluctuate, causing lights to flicker and sometimes go out.
In this article, we’ll discuss the ten reasons why lights may be flickering in your house and how to go about troubleshooting the problem. It will give you a better idea if you can fix the problem yourself or seek a licensed technician.
What Causes Lights To Flicker At Home?
Loose wiring can be a major cause of flickering lights in the home. It can happen if any internal wiring is not properly connected, which can be a fire hazard.
Old wiring can also be a big culprit, as it can become frayed over time, leading to similar problems.
Voltage fluctuations can also be a concern, as too little or too much incoming electricity can cause lights to flicker.
All these issues should be taken seriously and addressed as soon as possible. If you’re unsure what the issue is, it’s best to call an electrician to come and take a look. They’ll be able to determine the root cause and provide a solution.
1. Loose Wiring
We’ve all experienced it – those pesky lights flickering in our house. When this happens, we may start to feel frustrated and look for a quick solution.
One of the most common problems is loose wiring, which can cause electrical issues that manifest as light bulbs or fixtures flickering on and off.
It’s usually fairly easy to diagnose if you have a loose connection somewhere; just look closely at your wiring setup and any connections between the wires and light fixtures.
If something looks out of place or appears disconnected, tighten up any screws or bolts holding things together.
You might even want to replace old wiring with new ones to eliminate any potential voltage fluctuations that could occur due to an aged wire system.
Arcing
Loose wiring can cause arching when electrical current travels through the wires and creates sparks. These sparks can ignite surrounding material, such as insulation or other combustible materials, resulting in a potential fire.
A simple fix to this is to test and identify the areas where there are loose wires and have them tightened as soon as possible.
2. Old Wiring
Old wiring can also be the culprit behind flickering lights in your home. If you have an outdated wiring system, it might not be able to handle the current load of electricity running through its circuits.
This could lead to voltage fluctuations which can cause light bulbs and fixtures to flicker on and off. In this case, it’s best to call in a professional electrician who is licensed and experienced with electrical wiring.
They will be able to inspect your entire system and make sure that everything is up-to-date and safe. Additionally, they may suggest replacing any old wires or circuit breakers if necessary.
3. Voltage Fluctuations
When it comes to flickering lights, voltage fluctuations are often the cause. Loose service conductors or an overloaded circuit can lead to these changes in electricity levels, causing light bulbs and fixtures to flicker on and off.
This is especially true for fluorescent bulbs that operate on a higher wattage than standard incandescent bulbs – they’re more prone to voltage issues because of their sensitivity.
Even LED bulbs with dimmer switches installed may have this issue if the switch isn’t compatible with the bulb type being used.
4. Utility Service
An unsteady voltage supply from the utility service is a major factor in voltage fluctuations that cause lights to flicker.
When the voltage supply from the utility is unsteady, the lights connected to the supply will also experience fluctuations in their voltage supply.
This can cause them to flicker, dim, or even turn off completely. Unsteady voltage can be caused by a variety of factors, such as a faulty connection or a high demand on the power grid.
5. An Overloaded Circuit
Explain how an overloaded circuit can cause lights to flicker in two short paragraphs.
An overloaded circuit occurs when too many electrical devices are connected to one circuit, causing the electrical current to exceed the circuit’s maximum current capacity.
When this happens, the circuit breaker or fuse is designed to shut down the circuit. However, if the circuit breaker or fuse is faulty, the circuit will remain energized, causing the electrical current to fluctuate.
This fluctuation can cause lights to flicker. Flickering lights are a sign of an overloaded circuit and should be addressed by an electrician to prevent further damage to the circuit and to ensure the safety of the people in the house.
6. High Powered Electrical Appliances
Appliances with a high power demand can also cause lights to flicker if they are wired in the same circuit as the lights or if there are any internal issues within the appliance itself.
Here are some high-powered electrical components that can cause lights to flicker when turned on:
- AC Unit When AC comes on, motors start up, compressors cycle off and on, and power surges through lines as fans turn on or off.
These changes within the electrical system can cause fluctuations in the current, resulting in flickering or dimming lights. - Clothes Dryer
Lights will dim when a clothes dryer starts due to poor electrical connections, loose bulbs, and both lights and dryer being on the same circuit.
As the dryer starts, the motor within will draw a high starting current, reducing the power being shared with the lights and causing them to dim or flicker. - Water Heater An electric water heater will cause lights to flicker, a faulty heating element, or a potential wiring problem to or within the device.
Inadequate electrical outlets, loose connections, faulty switches, and improper installation of wires may also contribute to light flickering. - Water Pump
A water pump can cause lights to flicker if the current draw to the pump exceeds what it normally does.
Issues such as worn wiring, bad capacitor, and an aging motor can have an effect on the amount of current a pump draws when it starts which in turn witll cause lights to flicker.
7. Faulty Breaker
Faulty breakers can also cause lights to flicker. This occurs when a circuit breaker fails to properly regulate the flow of electricity, allowing too much or too little power to flow through the circuit.
When this happens, the lights in the affected area will flicker as the voltage fluctuates. Additionally, the breaker may trip, causing a sudden power outage.
Faulty breakers can also cause other issues such as blown fuses, dimming lights, and tripped GFCI outlets.
By replacing the faulty breaker with a new one, the voltage fluctuations and flickering lights can be eliminated.
8. Faulty Light Switch
A malfunctioning light switch can be a reason why lights flicker for a few reasons. The first is if the switch is worn out or damaged, it can cause the electrical current to become intermittent.
This means that the light will flicker on and off as the current fluctuates.
The second reason is if the switch is loose or improperly wired, it can cause a short circuit. This means that the switch is not properly controlling the current, causing the lights to flicker.
Lastly, if there are insects that live and build nests inside the switches eg. ants, they can also dirupt the flow of current causing lights to flicker.
9. Loose Light Bulb
Loose bulbs can cause lights to flicker in a few different ways.
Firstly, if the connection between the bulb and the socket is not tight, then the electricity can be intermittent, causing the light to flicker.
Secondly, if the bulb is loose then the filament inside the bulb can move, resulting in flickering. This is because the filament is constantly being moved around, which disrupts the flow of electricity.
Lastly, a loose bulb can cause an electrical arc to form, which can cause the light to flicker. This is because the arc jumps across the gap between the bulb and the socket, which causes the light to flicker.
10. Type Of Light Bulb
CFL light bulbs are known to flicker when they are first switched on, or when they are the first bulb in a circuit. This is because the CFL bulb takes a few moments to reach its full brightness.
The flickering is more noticeable when the bulb is first switched on, as it needs to warm up before it reaches its full brightness.
LED light bulbs can also flicker if there is a problem with the current or voltage running through the circuit. If the current is too high or too low, or if the voltage is too low, the LED bulb may start to flicker.
This can be caused by a faulty wiring or switch, or if the circuit is overloaded with too many lights or appliances.
Troubleshooting Flickering Lights In The Home
Let’s start with checking the breakers – if one of them has been tripped, the lights will start flickering.
Then, we should check the light switches – if they’re loose, they could be causing the problem.
If neither of those are the issue, we’ll need to look elsewhere.
Could be a wiring problem – let’s take a look!
Check Breakers
Do you ever notice the lights in your home flickering inexplicably? It’s a sure sign of something off with the electrical system.
The first thing to check is the breakers. If an air conditioner, loose bulb or even an incandescent bulb are connected on the same circuit as any large appliance, it can cause too much power draw and trip the breaker.
Inspect each service cable connection and make sure that there isn’t anything wrong with them before checking for a dedicated circuit being overloaded by multiple appliances running at once.
Once everything checks out okay, replace all broken bulbs or switch them to LEDs if necessary; this will reduce energy consumption and help prevent further overloads.
With these simple steps, you’ll be able to diagnose the root cause of your mysterious flickering lights and get things back up and running smoothly!
Check Light Switches
The next step in troubleshooting flickering lights is to check the light switches.
Worn-out or loose electrical connections can cause occasional light flicker and, even worse, could be a fire hazard.
It’s important to inspect all of your switch plates for any signs of discoloration, which could indicate an overheating issue due to insufficient electrical voltage.
If you notice anything that looks concerning, it’s best to call a professional electrician immediately as these types of issues can lead to serious house fires if left unchecked.
If everything appears normal with the switch plates, then make sure each connection is firmly secured into place; wiggling them around may reveal any potential poor contacts that need tightening up.
Additionally, ensure no wires are exposed where they shouldn’t be as this also can create dangerous situations from accidental contact with other components inside the walls leading to potentially hazardous electrical fires.
To prevent future problems, use LEDs instead of incandescent bulbs whenever possible and keep an eye on your breakers just in case something else goes wrong down the line.
With regular maintenance, you should have no problem keeping your home illuminated without worrying about flickering lights again!
