How to solve the induction cooker failure E3, and what happens to the induction cooker E3

If there is e3** in the induction cooker, it should be a problem with the grid voltage.

The E3 protection is a type of protection that induction cookers have (of course. The fault display** is not necessarily the same), and its purpose is to prevent the thermistor branch from opening and causing temperature runaway. Because the setting of this protection value in the induction cooker directly affects the low-temperature working performance of the induction cooker, it is for some products that cannot be started at low temperature.

To check this protection circuit in particular, it can generally be considered normal as long as it can ensure that it can work normally in the -5 environment.

What to do if the induction cooker shows e3.

The occurrence of E3 in the induction cooker is a malfunction of the thermostat.

The E3 alarm of the induction cooker belongs to the high voltage protection, and its purpose is to prevent the temperature runaway caused by the open circuit of the thermistor branch. Induction cooktops will only work properly if the voltage is between 175-285V. When a mains sampling circuit component fails or leaks, it will be detected by the CPU and E3 will appear.

First of all, it is necessary to confirm whether other electrical appliances in the home can work normally, and if so, you can rule out external factors and determine that the induction cooker thermostat is faulty. The back cover needs to be removed to check if the thermostat is working properly. If the thermostat is normal, check that the sensor is positioned correctly.

When the induction cooker is moved, or if it is impacted, the temperature sensor will be offset, and the temperature cannot be accurately monitored. In this case, it is only necessary to adjust the position of the temperature sensor.

Precautions for the use of induction cooker

1. The table top where the induction cooker is placed should be flat. If the table top is uneven, so that one foot of the induction cooker hangs in the air, the gravity of the cooker will force the stove to force the shape of a plum or even damage it when it is used.

2. The induction cooker in the work heats up with the heating of the pot, so it is necessary to pay attention to the inlet and exhaust holes of the induction cooker without blockage, and the intake and exhaust are smooth and free of stagnation. In addition, once it is found that the induction cooker is cracked and the fan stops rotating, the power should be turned off quickly to cool it down naturally and then sent to the maintenance station to check the cause of the failure, and it can be used again after it is completely repaired.

3. Try to choose special pots and pans for induction cooker to match the use of induction cooker. In addition, there is a certain limit to the load-bearing capacity of the induction cooker, and excessive weight will cause damage to it.

Answer how to solve the induction cooker E3 1, the temperature of the induction cooker E3 is usually too high in the ceramic plate, and the protective measures are started, which may be the sensor failure of the induction cooker, resulting in no way to transmit the actual temperature to the motherboard, so that the motherboard has no way to work, at this time it is recommended to replace the new sensor.

2. It is also possible that the position of the sensor is incorrect, resulting in the detected temperature is not the actual temperature of the board, and it is recommended to reinstall the sensor.

3. It is also possible that the thermostat is faulty, so the heating wire does not stop working, so it cannot receive the stop instruction from the thermostat, and it is recommended to replace the thermostat with a new one.

Solution: E3: Ceramic plate high temperature (main sensor bad): IGBT overheat protection. Check whether the IGBT temperature detection thermistor is open, and whether the fan circuit or 18V power supply circuit is normal.

The power supply of the induction cooker requires very good contact, so as to avoid unnecessary heating caused by the increase of contact resistance and the increase of current caused by bad contact.

Expand knowledge: Induction cooker, also known as induction cooker, is composed of high-frequency induction coil (i.e., excitation coil), high-frequency power conversion device, controller and ferromagnetic material pot bottom cooker. When used, an alternating current is introduced into the ** circle, and an alternating magnetic field is generated around the coil, and most of the magnetic field lines of the alternating magnetic field pass through the metal pot body, generating a large number of eddy currents in the bottom of the pot, thereby generating the heat required for cooking.

It is a product of the revolution in the modern kitchen, which allows the heat to be generated directly at the bottom of the pan without the need for open flames or conduction heating, so the thermal efficiency is greatly improved. It is a kind of high-efficiency and energy-saving cabinetry, which is completely different from all traditional fire-based or fire-free conduction heating kitchenware. An induction cooker is an electric cooking appliance made using the principle of electromagnetic induction heating.

There is no open flame during the heating process, so it is safe.

Classification: According to the power of the induction cooker, it can be divided into two types: household induction cooker and commercial induction cooker

According to the classification of the stove, the household induction cooker can be divided into single-head furnace, double-head furnace, one electric and one gas, and multi-head furnace

The working voltage of the single-head furnace is 120V-280V, the most common is 1900W-2200W, which is widely used in home stir-frying and cooking; It was developed relatively early and has been widely used in China;

The working voltage of the double-head furnace is also 120V-280V, at present, there is a flat and a concave and double-flat in the domestic market, the general single-head power is 2100W, and the double-head work at the same time does not exceed 3500W, and there are not many domestic users at present;

One electricity and one gas is the product of combining induction cooker and gas stove, one burner can use traditional gas, and the other burner uses induction cooker, with a general power of 2100W, which is an emerging product in the past two years;

Multi-head furnace, generally two induction cooker stoves plus a far-infrared stove, at present, there are very few domestic production, and now only the introduction of foreign technology by Midea is doing; Commercial induction cooker: mostly 380V voltage, 3-35kW, and widely used, frying, frying, frying, boiling, steaming, stewing, stewing, grilling, potting and so on. 50% less fuel cost than traditional oil stoves, and 60% less fuel costs than traditional gas stoves.

No open flame, no heat radiation, no smoke, no ash, no pollution, no increase in room temperature, no production of CO, CO2, SO3 and other harmful substances, the environment is protected. The kitchen is quiet, clean and refreshing, leaving the chef feeling comfortable and physically and mentally healthy. It is a veritable eco-friendly product.

Applicable occasions: any place where traditional stoves are used, such as hospitals, factories and mines, hotels, restaurants, colleges, institutions, etc.; Ideal for unfueled** or fuel-restricted applications such as basements, railways, vehicles, ships, aviation, etc.

E3 refers to the temperature of the induction cooker ceramic plate too high protection, when E3 has a problem, the cause and solution are as follows:

1. The sensor is damaged, resulting in the inability to transmit the real-time temperature to the motherboard, so that the motherboard stops working, and the sensor can be replaced to solve the problem;

2. The position of the sensor deviates, resulting in the detected temperature not being the temperature of the actual panel, which can be solved by re-fixing and installing the sensor;

3. The thermostat is damaged, resulting in the heating wire being working all the time, and the thermostat cannot be received from the thermostat to stop heating, and the thermostat of the induction cooker needs to be replaced.

Summary. Hello, 1. The induction cooker has a fault self-test function. The E3 display illustrates high voltage protection.

2. At this time, we need to test whether the voltage at home is normal, if it is normal, it means that it is not the cause of the voltage at home, and if it is not normal, it means that there is no problem with the induction cooker itself.

3. If there is a problem with the induction cooker itself, it means that the voltage protection sensor of the induction cooker is faulty or the voltage caused by the fault inside the induction cooker is too high.

How to eliminate the E3 fault of the induction cooker?

Hello, your question has been received, and now the answer is being sorted out for you, typing is a bit slow, wait a minute.

Hello, 1, the induction cooker has a faulty self-inspection reputation stove noisy. E3 display indicates high-voltage protection 2, at this time we have to test whether the voltage at home is normal, if it is normal, it means that it is not the cause of the voltage at home, if it is not normal, it means that there is no problem with the induction cooker itself 3, if the problem of the induction cooker itself, it means that the voltage protection sensor of the induction cooker is faulty or the voltage caused by the fault of the induction cooker is too high.

Good. Hello, I hope it can help you, I wish you a happy life and all the best.

Where should electromagnetic faults be checked and discharged?

Hello, induction cooker failure, first check whether the power cord is damaged, whether the plug is wet, and the contact is not good.

That's fine, I'm talking about a malfunction inside the induction cooker.

Hello rotten potato, the magnetic stove should be a habit to overhaul the electric hunger silver, and if the induction cooker fails, the high-pressure part of the socks should be checked first and then the low-voltage part should be overhauled, because the high-voltage part has the highest failure rate.

The inside of the induction cooker is full of oil, so it is not recommended to disassemble it.

If the induction cooker at home has been used for a long time, it will show some ** faults. What is the fault of the induction cooker E3? PChouse will take you to find out.

The induction cooker shows that E3 is a fault**, which indicates the high temperature (the main sensor is bad), which means that the main sensor of the induction cooker is faulty. The sensor is a kind of detection device, which can feel the spine of the measured information, and can transform the felt information into an electrical signal or other required form of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

The solution is to make sure that other electrical appliances at home can work normally, that is, the internal circuit of the induction cooker is faulty, and each induction cooker has a sampling circuit with a market voltage, which can work normally when the voltage is between 175 and 285V! When the detected voltage is applied to the CPU when the mains voltage sampling circuit component fails or leaks, the CPU is falsely protected by false alarms.

The buttons of the induction cooker are of the light touch type, and the fingers should not be too heavy when using, but should be lightly touched and pressed on the grinding ruler. When the button is activated, the finger should be removed and not held down to avoid damaging the reed and conductive contact.

How to repair the E3 fault of the <> induction cooker: E3 is a kind of protection that the induction cooker has, the purpose of which is to prevent the temperature runaway caused by the open circuit of the thermistor branch. Because the setting of this protection value in the induction cooker directly affects the low-temperature working performance of the induction cooker, for some products that cannot be started at low temperature, the pre-circuit of the protective limb should be specially checked.
