Blinking light in an apartment or a country house is a fairly common problem. It is caused by unstable voltage. Once faced with such a nuisance, you need to find out the root cause as early as possible. This is due to the fact that problems with electricity lead to the failure of expensive household appliances and electrical appliances, and also cause a short circuit, leading to a fire.
The light in the apartment is flashing: reasons
There are different types of flicker and how to eliminate them. First of all, you need to find out the root cause of the unpleasant phenomenon and find the problem area. If the lighting flickers in only one room, the reasons lie most often in the junction box located inside the room. It is not recommended to repair it on your own; a qualified specialist will speed up the repair process and make it efficiently.
If the lighting flickers throughout the apartment, observe the light on the staircase and ask the neighbors if they have noticed something similar. If not, the reason lies in the switchboard.
Light flashes throughout the room
If the lighting flickers throughout the apartment, as well as at neighbors and in the entrance, the services that serve the house should fix the problem.
Why does the light blink:
- The most common reason is overloading the power grid. This is observed if in several apartments the owners use powerful household appliances, for example, heaters, air conditioners.
- The house uses powerful household appliances and electrical appliances, but at the same time the wiring is outdated, has not changed since the days of the Soviet Union. Decades ago, the number of appliances in homes could be counted on the fingers. The solution to the problem is a complete replacement of the wiring or the additional installation of a step-down transformer.
- Flickering can be triggered by scheduled repairs at the entrance. Often, repairs are accompanied by the use of a hammer drill, drill, welding machine and other devices that consume a large amount of electricity.
In the latter case, it is better to observe the phenomenon. If the flickering stopped with the end of the work, there is no reason for worry. If the blinking of the lighting has not stopped, they look for and fix the malfunction.
Individual light bulbs are blinking
If during the inspection it was revealed that only one light flickers in a separate room or lighting device, the elimination of the breakdown will be completely different.
- Typically, a flickering lamp indicates that it is time to replace it with a new one.
- There are times when a new light bulb flickers. A defective item may have been purchased.
- The reason may lie in a faulty switch. It is necessary to observe how he "behaves". Defective electrical appliances often emit abnormal noises such as crackling.
A common cause of flickering is dirt and dust getting on metal conductors in switches or the lighting fixture itself. You can solve the problem yourself, just clear the contacts.
What to do with faulty wiring
If, after all possible manipulations with the switch and bulbs, the light continues to flicker, most likely, poor-quality electrical wiring is carried out at his house. A visual inspection of the switchboard, in particular the wiring line that powers the lighting fixtures, will help to verify this. It is important to carefully check the contact connections in the junction box itself. Usually, such problems arise due to the violation of the integrity of the conductors or when using aluminum wiring, which has low resistance and strength.
The solution in this case is one - to replace the damaged area or all the wiring in the apartment.
The services providing and maintaining the home must be responsible for the quality and reliability of the services provided, and also maintain voltage within acceptable limits. At home, the optimal range is between 210-230 V.
However, unstable tension is not always the result of poor quality services. The source of the problem may be the residents of the house, who turn on a large number of powerful appliances. Also, drops are observed when starting devices equipped with electric motors. When reversing and starting, there is a subsidence of the network.
Household appliances and lighting
Lighting is built into some lighting fixtures: kitchen hoods, ovens, microwave ovens. Flickering in them is sometimes a confirmation of the malfunctioning of a household appliance. To establish the cause, examine the cable in the switchboard that powers the specific device. If all other household appliances are working properly, no defects were found in the wiring, the reason lies in the device itself.
It is necessary to immediately disconnect the device from the voltage. You should try to replace the light bulb in it and check the contacts, perhaps they are oxidized and dirty.
It is strictly forbidden to work with any household appliances without special protective equipment and tools. You can only use the standard controls without disassembling the devices. If a person does not have the skills of an electrician, it is better to contact a qualified specialist. Electroshock does not warn about itself in advance, and the consequences can be dire.
