The electric kettle suddenly doesn t work, who knows what the reason is?

I opened the base, and the heating resistance wire inside broke. This is the case that 80% of electric kettles are broken, and if your kettle has been used for more than two years, you don't have to repair it and replace it with a new one. One is for safety, and the other is that a pot is not expensive for more than ten yuan.

The electric kettle suddenly can't be used, the electricity in this description may be burned out, or um, when boiling water, you don't pay attention to getting water, mixed electricity, this is possible, if you can repair it, you can repair it, you can't repair it, you can change it to a new one, now this kind of thing is still very cheap.

There are many reasons why the electric kettle cannot be used, mainly the following points: 1. Poor contact between plugs and sockets; 2. There is an open circuit in the power line; 3. The metal sheet in the base interface is deformed or ablated, resulting in poor contact; 4. Ablation or poor contact of switch contacts or power cord connectors; 5. The contact of the thermostat is ablated or damaged; 6. The heating element is damaged.

Poor contact of plugs and sockets, dented and deformed metal sheets in the base, ablation of switch contacts, ablation of thermostat contacts, loose ablation of connecting wire connectors, and damage to heating pipes may cause problems such as non-heating.

The electric kettle suddenly doesn't work, who knows what the reason is? If it can't be used, it may be a short circuit in the line, or it may be a poor contact.

Hello, generally speaking, the electric kettle suddenly can't be used, it is usually a problem with the circuit, you can take it to the after-sales service department to check it.

First of all, check the base of the electric kettle, is the power part good? If there is a multimeter, measure the switch and heating element of the electric kettle, the principle of the electric kettle is very simple, and it is also very easy to repair.

1. Most of them are the problem of temperature control, because temperature control is the heart of the entire electric kettle, and its main function has been to control the water to automatically disconnect from the power supply, or connect the power supply, and accept the corrosion of steam for a long time, resulting in the deformation and rust of the temperature control spring steel sheet, so that the power failure or power on can not be normal;

2. If the electric kettle is energized and the heating plate is not heated, this fault should consider what material the electric kettle is;

3. If it is a plastic kettle, it is generally enough to replace the heating plate directly;

4. But if it is a stainless steel kettle, it is estimated that the entire steel pot body of the electric kettle will be scrapped, because the heating plate of the stainless steel body is welded, there is no way to replace it, the heating plate of the stainless steel kettle, and some accessories of the kettle are not the same as the mold of each manufacturer, so if there is a problem with the electric kettle, it should be returned to the factory directly for maintenance.

The reasons and solutions are as follows:

1. Most of them are the problem of temperature control, because temperature control is the heart of the entire electric kettle, and its main function has been to control the water to automatically disconnect from the power supply, or connect the power supply, and accept the corrosion of steam for a long time, resulting in the deformation and rust of the temperature control spring steel sheet, so that the power failure or power on can not be normal;

2. If the electric kettle is energized and the heating plate is not heated, this fault should consider what material the electric kettle is;

3. If it is a plastic kettle, it is generally enough to replace the heating plate directly;

4. But if it is a stainless steel kettle, it is estimated that the entire steel pot body of the electric kettle will be scrapped, because the heating plate of the stainless steel body is welded, there is no way to replace it, the heating plate of the stainless steel kettle, and some accessories of the kettle are not the same as the mold of each manufacturer, so if there is a problem with the electric kettle, it should be returned to the factory directly for maintenance.

Possible reasons are:

1. The heating plate is damaged.

2. The thermostat or temperature fuse is damaged, resulting in the heating plate not being energized. The thermostat or insurance must be replaced directly.

3. There is a high possibility of leakage, it may be a line, it may be an electrical appliance, and the power consumption during this period will increase the voltage of the small power grid, and some bad lines or electrical appliances will leak due to the increase in voltage.

4. The internal circuit is damaged, resulting in the heating plate not being energized. It is also a direct replacement line.

The working principle of the electric kettle: the water vapor generated when the water boils deforms the bimetal sheet of the steam temperature sensing element, and this deformation pushes the power switch to power off by the lever principle. It is not self-resetting when it is powered off, so the kettle will not automatically reheat after the power is off.

There are many electric kettle products on the market that choose not stainless steel but high manganese steel, which is due to the fact that the price of nickel in the market is much higher than the price of manganese, and some manufacturers choose high manganese steel in order to save costs. The corrosion resistance of high manganese steel is poor, and it is easy to precipitate a large amount of heavy metal manganese due to corrosion during use, and long-term excessive ingestion by the human body will bring health risks.

After the electric kettle is used for a long time, the surface of the electric heating pipe is covered with a thick layer of white mineral sediment, that is, scale. This kind of excessively thick scale is not easy to conduct heat, which not only increases power consumption, but also affects the service life of the electric kettle.

So use edible white vinegar to remove limescale. Pour 0 5L of edible white vinegar into the pot and soak it for more than 1 hour, and then wipe off the scale on the electric heating pipe with a damp cloth.

Possible reasons are:

1. The heating disc is damaged.

2. The thermostat or temperature fuse is damaged, resulting in the heating plate not being energized. The thermostat or insurance must be replaced directly.

3. The possibility of leakage is wide, it may be a line, it may be an electrical appliance, and the power consumption during this period will be small, and the voltage of the power grid will increase, and some bad lines or electrical appliances will leak due to the increase in voltage.

4. The internal circuit is damaged, resulting in the heating plate not being energized. It is also a direct replacement line.

Electric kettle is a common appliance in modern families, and people are prone to some failures in the process of using electric kettles, such as electricity but not heating. Today, the number of people will be answered for you one by one.

1. What should I do if the electric kettle is not heated.

If the measured resistance is still there, it means that the fault is in the pot body circuit, and the handle cover assembly should be disassembled for maintenance. The focus is on the power supply and touch (reset) switch and insulation switch. You can use the multimeter R1 gear to check whether the switch action and contact on/off are good.

If it is found that its action is not good, you can check whether the bending angle of the small tongue of the thermostat and the position of the switch connecting rod are normal, otherwise they should be corrected separately. If the switch operation is normal and its contacts cannot be connected, it means that the switch reed or contact is damaged, and the switch box can be disassembled for cleaning and repair.

The indicator light is on, indicating that the power supply has been added to the indicator circuit, and the fault is in the electric heating pipe or its connecting part, and the electric heating pipe is damaged and the contact is poor. Remove the electric heating pipe and measure its resistance value.

The electric heating pipe is damaged and can generally only be replaced. The poor contact is mainly due to the serious corrosion or deformation of the contact reed in the power plug assembly, which can be disassembled and repaired by disassembling the switch box, and it is best to replace it if the damage is serious.

Second, what is the reason why the electric kettle is energized but not heated.

After powering on, it is not heated, the indicator light is not on, and the fault is often caused by the power supply not being added to the electric heating pipe circuit. When overhauling, you can first use the multimeter R10 to measure the resistance of the 3-pin plug L and N ends on the power line of the base. When normal, the resistance is not pressed when the reset switch is not pressed, and the corresponding resistance value of the 1500W electric kettle is about 32 when the button is pressed.

If the resistance value is still after pressing the button, it means that the heating tube circuit is not working.

If the power switch is normal, the fault mostly occurs in the insulation switch, first see whether the reed of the bimetal sheet is pressed against the switch contact rod (white plastic rod), if it is pressed too tightly, it can be bent upward with tweezers until the distance between the two. If the distance between the bimetal sheet and the switch lever is normal, the switch box should be disassembled, and the contacts and reeds of the insulation switch should be cleaned and repaired.

It can be seen that there is a reason why the electric kettle is energized but not heated, such as the power supply is not added to the electric heating pipe circuit, and the resistance of the 3-pin plug L and N ends of the power cord on the base can be measured with a multimeter R10 during maintenance. When normal, the resistance is not pressed when the reset switch is not pressed, and the corresponding resistance value of the 1500W electric kettle is about 32 when the button is pressed.
