Can the lights at home work, the rice cooker, the pressure cooker is not normal? 250

This problem is a common problem in the family, and it is actually very simple.

The power supply of the average home is divided into three parts:

The first is the lighting part, which refers to all the lights installed in the room. When we disassemble and install lighting equipment, we can turn off the switch of this circuit, but it will not affect the power supply of other circuits such as wall switches.

The second is the low-power part of the wall socket, which refers to the socket in the room that connects to electrical appliances such as TVs, refrigerators, computers, and desk lamps. This part of the circuit is closed and will not affect the power supply of other circuits such as lighting.

The third is the high-power part of the wall socket, which generally refers to the wall socket in the kitchen, which is used to connect dishwashers, microwave ovens, water heaters and other electrical appliances. This part of the circuit is closed and does not affect the power supply to the circuit outside the kitchen.

There is lighting in the room you mentioned, but household appliances such as rice cookers and washing machines cannot work without electricity, indicating that the wall switch is powered off, such as power short-circuit, power break, etc., you can carefully check the distribution box to see if there is a loop control switch turned off. If there is, just push it up.

You said that the light can use a rice cooker and a pressure cooker are not normal, it may be that your voltage is low and the voltage is unstable, so you can't use something that is too high.

Maybe it's a problem with the wiring in the house.

You can measure the voltage first, now many lamps and televisions and computers are used switching power supplies with a wide range of voltage, sometimes it can work normally, but rice cookers, pressure cookers, range hoods can not work normally.

That is, the power is insufficient, that is, the voltage is low, and the high-voltage power cannot be moved, and the converter needs to be installed.

Find a professional, or an electrician or something.

It may be that there is a problem with the store's review, or the voltage is unstable, so it is necessary to check it carefully and analyze what is the cause? It's best to find a professional electrician to take a look, because you still have to find a professional in terms of electricity, because your own messing affects safety.

It is the voltage instability, so it is necessary to check it carefully, analyze what is the cause of it, and find a professional to check it!

Low voltage may cause this phenomenon, find a professional to use a multimeter to measure it, professional things, professional people do.

Maybe there is a problem with the electricity of the socket, you see you are talking about the electrical appliances that want to be plugged in have a problem, and there is no problem if you don't plug in, you can find someone to take a look.

The lights and rice cookers at home, the pressure cooker are parallel circuits, the power of the lamp is small, and the low voltage is not affected, but the rice cooker and the pressure cooker are powerful, and the voltage is low.

An electric pressure cooker is an electrical appliance that can use a high-pressure environment to cook food faster and turn it into delicious cooked food. However, in the case of improper maintenance or carelessness, the electric pressure cooker also has certain minor problems. For example, why does the display light not light up during the steaming process?

This will directly cause the electric pressure cooker not to work, so I will give you a few reasons why the electric pressure cooker does not light up today!

Cause 1: The electric pressure cooker is not energized or there is a problem with the circuit. As we all know, all household appliances need to be energized to be used normally, once you find that the electric pressure cooker is plugged into the electric board and still does not light up, it means that there is a problem with the circuit of the plug-in board, or there is no power.

In this case, it is necessary to see whether other electrical appliances are energized normally in time, and the plug-in board should be replaced if needed.

Cause 2: The capacitor is damaged. We all understand that capacitors play an important role in electrical products, mainly using capacitors to block DC through AC, and also to store and release all the charges that can be used as filters, and then can output all signals.

It is the most important part of the electric pressure cooker, and all such situations need to be replaced in time. Replacing the capacitor requires a professional to repair it.

Reason 3: The circuit board is damaged. The circuit board is one of the most important components of an electrical appliance, and once there is no circuit board, all appliances will not be powered on again.

Through the connection and fixation of circuit boards, an electronic device can be composed of an electronic circuit with a specific function as in physics, and the specifications are relatively small and beautiful. It plays an indispensable role in electrical appliances. As long as there is damage to the circuit board, it means that the appliance can not be used continuously, so the circuit board should be replaced in time.

This also requires professional maintenance personnel.

The indicator light is on after the rice cooker is powered on, but the reason why the rice cannot be cooked and the maintenance:

1. The source wire is broken. Check the power supply wires with the ohmic stop of the multimeter;

2. The current limiting resistor is fused. At this point, the resistor can be checked with the ohmic stop of the multimeter. If the resistor is fused, it must be replaced by the current limiting resistor of the same model, and cannot be directly replaced by a wire;

3. The heating tube is burned out. A rice cooker without a current-limiting resistor works for a long time and burns out the heating pipe. At this time, check the heating element with the ohmic stop of the multimeter, and if it is broken, it must be replaced together with the heating plate.

First. There was a circuit break. In other words, there is a circuit in the circuit of the heating function.

The second current-limiting resistor is fused. Then it won't continue to work.

The third heating tube burned out. This needs to be replaced.

Wishing you a happy life!

The reason why the rice cooker is not heating may be that the fuse resistor is burned out.

The fuse resistor of the rice cooker may burn out because there are foreign objects on the bottom of the pot or the heating plate, so that the inner pot of the rice cooker cannot fully contact the heating plate, and if the temperature of the heating plate is too high, it will cause the fuse resistor to burn out.

However, at the same time, it protects the heating plate of the rice cooker, carefully check the foreign matter at the bottom of the rice cooker or the heating plate, remove the foreign matter and clean the bottom of the pot or the heating plate, and be careful not to throw off the safety resistor.

The bimetal sheet used to keep the heat of the rice cooker is accidentally adhered to the contacts, which is easy to cause the fuse to be burned out due to continuous heating, so pay attention to replacing the bimetal sheet.

If this is the case, it is necessary to carefully trim the inner pot deformed by the rice cooker to restore the original state, and the repaired inner pot can still be used, but the deformed heating plate cannot be used, and it must be replaced with a new one.

1.When the rice cooker light is on, it is not possible to cook, which is a common phenomenon.

2.The main cause is the blowing of the heated heating wire, or the damage of the electronic components of the touch switch.

The light is just on, and the cooking button has been pressed.

1.First of all, a white tube-shaped element in the rice cooker with a lead at the bright end and marked with 130° is clamped with pliers, and then the leads at both ends are connected together to power on. This method can only be used on an emergency basis and can be replaced as soon as the same component is purchased in the future.

2.First of all, change the electrical appliance to check whether the socket has electricity, borrow a multimeter, and first test whether each line is connected, including the power plug line. (Pay attention to see if the fuse is burned).

Then test whether the heating wire has burned out. (The heating wire has a certain resistance value, if there is no resistance value or infinity, the heating wire is broken, you can go to the hardware store to ask if there is the same specification.) Don't forget to bring your heating wire.

If there is, check whether there is a problem with the plug wire, and whether there is a bad contact, etc., and then press the switch for 5 seconds, open the lid, and if there is heat in the pot, it is a problem with the power indicator light, otherwise it is a local problem such as temperature insurance or temperature control inside the pot.

The voltage pot can't jump the light after cooking the rice is cookedReason:

1. The temperature control diode or temperature control resistor is damaged;

2. Deformation of the pressure switch or oxidation of the contact of the switch;

3. The temperature control switching relay is damaged (relatively rare).
