What is the reason why a light in the home circuit suddenly goes out while other electrical applianc

This situation is common in building residents, because there are several branch lines such as lighting, ordinary electrical appliances, and high-power (air conditioning) electrical appliances in the control box of the building residents, which are opened by their respective air.

Manage. If only one light goes out suddenly, first make sure that the other lights on the same lighting circuit are not on, which is caused by the tripping of the lighting line, otherwise this lamp is faulty.

One light went out, and the other appliances were still functioning. There are two reasons for this: First, the lamp has been broken for a long time. Second, the lamp port and the lamp are falsely connected, resulting in ineffective conduction. The solution is to change the bulb and tighten the lamp port.

1 The light is broken. 2. The lighting switch tripped.

In the home, lighting, sockets, and kitchen appliances are all independent.

There are many reasons why the lights don't light up! It is possible that the bulb has reached the end of its useful life and needs to be replaced with a new one. If the bulb still does not light up after replacing it with a new one, it means that there is a problem with the control circuit of the switch, and it is recommended to find a professional electrician to repair it.

This means that the light bulb in your house is broken, and it is okay to replace it with a new one, and there is no problem with the rest.

Only 1 light went off, everything else was normal, apparently the bulb itself or the rectifier was damaged.

Lighting circuit failure in the home needs to be checked and repaired, a light goes out for many reasons, it is possible that the lamp itself is broken, or there may be a faulty line.

In this case, I think it should be a problem with the mountaineering, it should not be a problem with the line, if there is a problem with the line, then he will not just simply wash his face, but will have a series of reactions. So when we do things, we don't have to worry about the existence of problems.

Hello! Judging from your description, it is likely that the lamp is out of order, first check whether the lamp is abnormal, and if there is a backup, you can also replace it.

This is because the lamp is connected in parallel with other electrical appliances. If the light is broken, it will not affect the use of other electrical appliances.

The light is broken or the power supply is malfunctioning.

There is a higher chance that the bulb will be broken.

Most likely, this light is broken.

1 The light is broken.

2. The control switch is disconnected.

The lights at home suddenly all went out, but the electrical appliances had electricity, and there were three problems with normal operation:

1. Whether the air switch or leakage protector at home trips, no tripping, go to the meter box of the home appliance to see whether the leakage protector at the lower end is tripped, if it trips, press the blue or red switch on the leakage protector, and then close the leakage protector, if it does not trip again, you can use electricity normally to indicate that it has been solved! If there is no power after closing, it may be that the leakage protector has burned out.

2. The leakage protector can not resume normal electricity after closing, indicating that the leakage situation is serious, and you can temporarily unplug all the sockets at home, especially high-power electrical appliances such as hoods, electric water heaters, air conditioners, washing machines, etc., and then try to restore electricity after closing.

3. If the air switch and the meter box leakage switch are not tripped, and the yellow light is lit on the smart meter, it means that the power supply company's system is automatically cut off because of arrears, and you can pay Alipay or WeChat; After payment, wait for the yellow light to turn off, and press and hold the white button on the smart meter.

There are the following possibilities:

1) When a certain light is turned on, the bulb flashes and goes out, and other electrical appliances are still working normally, and the fault is.

The filament is broken or the circuit is broken at the bulb;

2) When I insert the lamp plug into the socket in the original circuit, all the lights go out suddenly, and the fault is.

A short circuit occurs at the plug of the desk lamp;

3) When a lamp is turned on and off, sparks emerge from the wire joints of the lamp, and the lamp flashes and flashes, the fault is.

Poor contact at the wire joints of the lamp.

Analysis: (1) The resistance of the filament increases with the increase of temperature; After closing the switch, the bulb turns on and goes out, which means that the bulb burns out and the current in the circuit is too large, that is, the bulb resistance is small at this time

2) The reason for the excessive current in the circuit: one is a short circuit, and the other is that the total power of the electrical appliances is too large Both of these situations will cause the fuse to blow out or trip, so that other electrical appliances in the home will stop working

3) When there is a virtual connection at the wire joint, there will be sparks at the wiring, and it does not work when using electrical appliances

Generally, the power supply at home is divided into two ways, one is lighting, one is the socket, your home is lighting, your switch tripped, check the lamp, close the switch.

The power supply line of the lamp, the lights are all turned off, it means that it is not the problem of the bulb, usually the circuit is connected in parallel, as long as the bus of the lamp power supply is found, it is not the connector is loose, or the electric switch is broken, ......

Summary. Hello, if all the lights at home are off, but other electrical appliances such as refrigerator space can operate normally, generally speaking, there is a problem in the wire connected to the light, because all the lights are connected in series, that is to say, as long as there is a fault in one place, all the bulbs will go out, so you can find a professional electrician to help you repair whether there is a fault in the wire connection?

The lights at home suddenly all went out, but the electrical appliances were powered and working normally, is it a problem?

There was a switch on the fuse box that tripped, and the light was on for a second and jumped again.

It is very likely that there are too many lights on, causing it to trip, or it is possible that the wire connection is unstable.

There's a small blue button on the side of the switch, and I press it and send it again, but I can't send it.

It is very likely that the wires inside are burned and need to be replaced, which needs to be repaired and replaced by professional electricians.

Is the fuse in the fuse box burned?

Well, yes, it's very likely.

The lights are on in the kitchen! All outlets have electricity!

Didn't you say that all the lights are not on? It's likely that the lights in the kitchen don't use the same wire as the lights in your other rooms.

The air opening of the control light tripped, and the socket is supplied by another way of electricity, so there is electricity, as long as the air opening of the light is turned on, it can be restored to normal.

Before the lamp plug is inserted into the socket, the household appliances are working normally, and when the rear socket is plugged in, the lights at home suddenly go out Indicating that the circuit at the end of the lamp wiring is short-circuited, resulting in a sudden extinguishment

Therefore, d
