The electric kettle boils for a while and the power goes off? What s the deal with the electric kett

First of all, most of the reasons why we use the electric kettle to trip when boiling water is that the thermostat and the temperature fuse are very problematic, which will cause the heating plate to not be energized, and we can directly replace the thermostat or fuse.

Secondly, it may also be because of the leakage of the electric kettle will cause some lines to trip due to electricity, or it may be an electrical appliance at home, if the power used during this period is relatively small, the grid voltage will gradually increase, and there are some bad lines or electrical appliances will be caused.

There is also a possibility that the wiring inside the kettle may burn out, resulting in the heating plate not transmitting electricity.

This is a normal phenomenon, boiling water, the kettle will automatically cut off, but the water can not heat up again, it has to cool down, when the temperature drops to a certain extent, the natural kettle begins to work again, boiling the water until the water boils dry. Please note! When the water dries up, the kettle will **.

1. The electric kettle is opened at the same time with multiple electrical appliances at the same time, so that the electric power is too large and the power is automatically cut off, it is recommended to use the electric kettle alone for testing;

2. If the electric kettle is used for too long, or the power is cut off due to internal damage, it is recommended to overhaul it;

3. The electric kettle is a temperature control switch, with a temperature control probe, when the temperature is set, and the water reaches this temperature, the electric kettle will be powered off, it is recommended to check whether it is a temperature control kettle, and whether the water temperature is set too low.

The electric kettle will not be powered off after boiling for a while, but it will automatically cut off the power of the kettle after it is boiled, and then wait for it to get up.

It is recommended to replace the base under the electric kettle to prevent unnecessary trouble.

This should be caused by poor contact in a certain position, such as a dented metal sheet in the base, or a switch or thermostat.

The contacts are ablated, and the power cord is connected.

caused by oxidative rust.

If you have the conditions, use the elimination method to rule it out, put the electric kettle to another socket and try it, I mean another socket that can boil water normally. If it does not trip, it can be determined that it is the fault of the electric kettle, and if it still trips, it is recommended that you replace a larger circuit breaker.

The electric kettle heats up for a while and then loses power, which is caused by poor contact between the bimetal sheets.

The electric kettle will be turned off after a while, this is a hot hole, there is hair, Guangguang, and the item can be repaired.

When the furnace wire is broken, when the temperature rises, it expands and the contact point is disconnected. aqui te amo。

Possible reasons are:

1. Fever. The disc is damaged.

2. a thermostat.

or the thermal fuse is damaged, causing the heating plate to be powered. 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 is passed by the lever principle.

Push the power switch to power off. 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 high manganese steel instead of stainless steel.

This 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.

Hello dear, the electric kettle will be powered off after a while, the answer is as follows, it is usually installed at the bottom of the electric kettle or near the bottom of the side of the temperature control switch is damaged, you can see when you disassemble the kettle, the shape is cylindrical, there is a fixing screw mounting hole on each side, there are two connecting wires on it, you can see the words 110 or 105 on the surface after removing, some electric kettles have two such switches, but the installation position is different, the function is the same. This kind of temperature control switch is sold in general home appliance accessories stores or electrical repair points, about 5-10 yuan. When purchasing, be sure to buy the same switch as the original, not higher or lower than the original temperature value, otherwise the water will not be turned on or will not jump.

In addition, if the contact between the temperature switch and the wall of the pot is loose or separated, it may also cause the fault you said, first you check if it is not loose according to the previous method, and then use a heated soldering iron to heat the contact surface of the temperature switch for about 30 seconds, and do not hear a "click" sound, which proves that the switch has been damaged and must be replaced.

The contact is made of a bimetal sheet, because the metal is sensitive to heat expansion and contraction, so when the temperature does not reach the set value, the bimetal sheet is a curved shape, and its contact is closed and connected. When the water is heated to a set temperature, the heat of the water is transferred to the bimetal sheet in the thermostat, which straightens the contact and de-energizes it. When the temperature drops, the bimetal sheet returns to its original state, so that the contacts are connected to the energized and heated state.

The two sides of the bimetal sheet are conductors of different substances, and the double metal sheet is bent due to the different degree of expansion and contraction at the changing temperature, and touches the set contact or switch, so that the set circuit starts to work. This is more direct and timely, and can accurately sense the water temperature.

1. Fill the kettle with clean water, cover the lid, turn on the power and press the switch, it takes about 5 minutes for the kettle to boil the water and automatically cut off the power.

2. Add water to the kettle without covering the lid (note that the lid is not closed), you will find that the hot water in the kettle has been boiling, but the kettle has not been automatically powered off.

3. Add water to the kettle without covering the lid and heat it until the water in the kettle becomes boiling, let it boil for a while, and find that the kettle will not automatically cut off. Then close the lid of the kettle, stay for a short time and the kettle will automatically power off.

And once the water is boiling, the switch at the handle of the kettle cannot be pressed immediately, and it needs to wait for the temperature to drop before it can be pressed. These three small experiments can also confirm that the automatic power off of the kettle depends on steam, and the actual control switch device is a steam switch with a bimetal sheet.

After the electric kettle is filled with raw water, the upper cover should be covered and the lower power switch should be pressed to start the boiling water, the water will produce a large amount of water vapor when boiling, the electric kettle has an air guide pipe in the handle, and the water vapor reaches the bottom of the kettle along the air duct, and a bimetal sheet is heated, due to the different thermal expansion coefficients of the bimetal sheet, it is bent after being heated, and this bending force pushes the switch to reset and disconnect the circuit.

To sum up, a pot with a temperature switch will never boil to 100 degrees Celsius (more than 80 degrees Celsius at high altitudes can make water boil). Because the kettle must be stopped several degrees in advance to ensure that the kettle stops heating stably, if it is not designed in this way, then the kettle with this temperature switch may never stop heating; There is no need to consider the above problems when using a steam kettle, as long as the water boils and the steam heats the bimetal, the heating can be stopped! The advantages and disadvantages of the two kettles are that the temperature of the kettle with the temperature switch is always close to the boiling point, but it can be kept warm and it can be automatically reheated after the temperature drops, while the other is only heated once to the boiling point without keeping warm!

This is an internal failure.

Pro, how long has the kettle been used, first, the reason why the electric kettle tripped, the reason for scale, the electric kettle has been used for a long time, and the surface of the electric heating pipe is covered with a thick layer of white mineral sediment, that is, scale. Too much scale will not be easy to conduct heat, which will not only increase power consumption, but also affect the service life of the electric kettle, and will also cause the electric kettle water to trip before it is boiled. The solution is to use baking soda to wipe back and forth in the limescale area, or pour the 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, and remove it.

2. Spring reason: The electric kettle trips because after the power is turned on to heat the water, it is boiled to a boiling state, so that the steam impacts the bimetal sheet on the switch, so that the expansion contact of the bimetal sheet disconnects the power supply. The bimetal is forcefully touched to the heating element through a small spring. When the electric kettle has been used for a long time, the spring loses its original elasticity, and after a period of power, the spring temperature is slightly too high, and the metal sheet will be disconnected in the circuit.

At this time, the electric kettle will trip if the water cannot be boiled, and the solution is to replace the spring.

2. The working principle of the electric kettle is to use the water vapor generated when the water boils to deform the bimetal sheet of the steam temperature sensing element, and use the deformation to push the power switch through the lever principle, so that the electric kettle will automatically cut off the power after the water is boiled. If it does not trip after boiling, it is necessary to pay attention to whether the temperature control of the electric kettle has failed, causing the switch to fail. You can disassemble the circuit guard board, find the temperature control variable resistor, adjust it and try it, if it still can't solve the problem, it is recommended to find a professional maintenance master to solve it.

Questions. Where is the spring.

In the handle or the display light position.

The electric kettle will be heated for a while and stop for a while, and the switch will not jump, which may be due to the following reasons:

1. There is a problem with the temperature sensor of the kettle;

2. The heat conduction process is not good;

Change to 3, anti-dry burning induction metal sheet can be removed, the stove imitation so that there is less of an anti-dry boiling function and the same as ordinary electric kettle, remove it will not jump, but to manually prevent the water from boiling dry.

Summary. It may be that the metal piece of the temperature sensor is broken, or it may be that you always open the lid to boil water, causing the water vapor to enter the temperature sensor part and make it malfunction. Or maybe some other lever mechanical part is broken.

You look at the air drying for a while, if it can't be good, then replace it with a new one, it's not expensive.

What is the problem of uninterrupted power after the water in the electric kettle is boiled?

It may be that the metal piece of the temperature sensor is broken, or it may be that you always open the lid to boil water, causing the water vapor to enter the temperature sensor part and make it malfunction. Or maybe some other lever mechanical part is broken. You look at the air drying for a while, if it can't be good, then replace it with a new one, it's not expensive.

There is a temperature control switch on the bottom heating plate of the electric kettle, and when the temperature reaches 90 to 100 degrees, the contacts of the temperature control switch will automatically pop on and off the power. The switch contacts close automatically when the temperature drops. In your case, the temperature control switch is broken, and you can buy one and replace it according to the model after disassembly.

Summary. The main reason why the electric kettle does not trip after boiling water is because there is a problem with the steam switch or temperature control switch.

The main reason why the electric kettle does not trip after boiling water is because there is a problem with the steam switch or temperature control switch.

Because the electric kettle is connected to the power section hall to heat the water to 100 degrees Celsius, the water will begin to boil, usually the steam switch of the ordinary electric kettle is in the handle position, when the double gold in the steam switch does not hold the hidden piece, the switch contact is opened by the hot steam impact, so as to disconnect the power supply. If the steam switch fails, it won't trip and will continue to burn until the water is dry.

There are two situations, one is that in the case of no water, the electric kettle will reach 100 degrees after being powered on for a while, and the temperature control switch will automatically cut off the power supply; Second, in the case of water, the water will automatically be powered off before it is boiled, indicating that the temperature control switch has been damaged.

Answer: Hello, the electric kettle will automatically turn off the power before it is boiled Reasons and treatment methods: 1. It may be because the surface of the electric heating pipe of the electric kettle is stained with a layer of extra-thick scale, and the scale is too poor and not easy to conduct electricity, so it cannot boil water in the end. The solution is that people use baking soda or a special scale cleaner to remove the scale, and the electric kettle can be used normally.

2. The electric kettle will automatically cut off the power before it is boiled, it may be that when the water is about to boil, the steam impact the bimetal sheet above the switch will expand and disconnect the power supply, because the spring of the bimetal sheet loses its original elasticity. The solution is to replace the spring of the electric kettle. 3. The electric kettle will automatically turn off the power before it is boiled, and it may be that its temperature control switch is damaged, people use a screwdriver to turn the screw at the bottom of the electric kettle, find the temperature control switch on the bottom lid and replace it.
