It means that there is no pot and pan, which is a problem with the pot inspection circuit. Generally it is a large resistance bad or 5uf capacitor.

To buy an induction cooker online, you have to buy it on a large platform with quality assurance such as First Department Store or JD.com.

Supor. Induction cooker failure**e0 means internal circuit failure.

The range of internal circuit faults is very wide, either very simple or very complex, ranging from inter-line leakage, to abnormal power supply, abnormal voltage of various detection signals obtained by MCU, etc., including key board leakage, oil pollution is too dirty can appear E0, which is an incurable disease.

When overhauling, in line with the idea of from simple to complex, follow the easy to.

Difficult maintenance principle.

The maintenance starts from the power supply, and the three major voltages of 300V, 5V and 18V are first tested.

5uf safety capacitors.

The voltage at both ends must be about 300V (between 285V and 320V), the voltage is abnormal, and the induction cooker does not heat up and does not work or causes burning out the power tube. The voltage is insufficient, usually the 5uf capacitor fails.

5V is the main working voltage of the system and the reference voltage of each detection point, and the voltage cannot enter normal operation if the voltage is abnormal.

18V is the working voltage of the power output drive circuit and the fan, if the voltage is abnormal, it will stop working at least and lose the power tube.

Check a few other major capacitors.

It's resonance. After the capacitor fails, it will not be heated, the heating efficiency will be low, and the power tube will be damaged.

2UF is the power grid filtering and anti-interference capacitor, which will be intermittently heated or not heated after failure, and the life of the power tube will be affected at worst.

10UF 450V is the main filter capacitor for the secondary power supply.

After failure, it can cause 5V and 18V abnormality, and damage the power chip.

Check whether the circuit board is too dirty, including the key control board, whether the keys are leaking, etc., and clean them up, or sometimes there will be unexpected gains.

Check the synchronous detection circuit, and check whether the resistance value of the main resistance of the pot inspection circuit has become larger.

Do a repair welding for each high-power component, especially chokes, large capacitors, and rectifier bridges.

Power tubes, constantan wires, connectors everywhere.

Wait. The above inspection can basically rule out the problem of E0, if it is not solved, it is necessary to systematically check and measure the changes in the voltage parameters of the control chip from the details, and take the resistance method, voltage method, current method, waveform method, etc. to check and judge the fault position. Due to the wide range of E0 faults, it is not possible to go into detail here.

The E1 test is not suitable for cookers or pans are not suitable for induction cooktops. In the past, when it was good, it would also appear e1 if the pot was removed, and if the pot was removed from Xilu before, this fault was mainly due to the failure of the pot detection circuit! Or maybe there's a problem with the power supply.

Repair method: replace the pot first, if it still doesn't work, check whether there is an obvious break in the internal circuit, if found, connect it. If there is an obvious fracture without Kai code, it is recommended to go to the designated repair shop for repair.

Hello dear, I'm glad to answer for you, Supor induction cooker shows E2** is the internal heat dissipation of the machine is not smooth or the temperature sensor in the machine is faulty, the solution steps are: 1. You can check the thermistor of the first surface of the IGBT. Then carefully check whether the connection between the IGBT temperature measurement thermistor and the CPU is disconnected, and whether the C104 ceramic capacitor with 5V grounding at one end of the thermistor is short-circuited.

2. If the damage on the wire reel temperature measurement thermistor LM339 is damaged, it will also show that E23 will be turned on after a while, and after a while, see if the fan is normal, and the temperature measurement thermistor can also cause this fault. 4. The exhaust outlet is blocked. 5. Sensor failure.

If the sensor is faulty, the thermistor needs to be replaced. Professional maintenance personnel can be asked to overhaul.

1. The pot detection function displays: if the induction cooker is removed in the process of use, the buzzer will automatically alarm, and the induction cooker will automatically shut down if the pot is not put on within 30 seconds. In this case, the fault can be solved by simply putting the pot on it in time**e0.

2. Power tube over-temperature protection: In the process of using Supor induction cooker, if the power is too high, it will automatically stop heating, and then the fault **e0 will be displayed, and it will continue to work after the temperature drops.

3. Anti-interference protection of induction cooker: If the instantaneous voltage exceeds 330V is detected during the use of the induction cooker, the induction cooker will automatically stop working, and the fault **e0 will be displayed, and the heating will continue after the voltage returns to the normal value.

Hello, e0 is an internal line fault, it is recommended to check the sampling resistor, if it is okay, change the board, thank you for adopting.

1. Supolaire induction cooker failure**.

There are roughly three common faults of induction cookers:

1 Explosion - burn fuse and IGBT.

The specific performance is that there is no response when the power is on, and the whole machine does not work. When we disassemble the machine, we will find that the insurance has exploded, and it has exploded so badly that the glass walls of the insurance have exploded black. If we check further, we will find that the IGBT under the large radiator is also broken, and sometimes the rectifier bridge is also burned, but the rectifier bridge is much stronger than the IGBT, and in general, only the IGBT is burned.

What to do if the induction cooker is broken.

What to do if the induction cooker is broken.

In the face of this situation, we should not rush to replace the parts and test the machine. Also check if there are any other bad parts. When I encounter this situation, I will measure all the resistance of the large resistance value in the circuit, as well as the two triodes (8050, 8550) that drive the IGBT, and then see if the 300V filter capacitor and resonant capacitor are bulging.

If that's all right, replace all the bad parts except the IGBT. At this time, the power test machine is used to test whether the B pole 0V of +5V, +15V or +18V and IGBT is normal. Only when these voltages are normal, can He Travel install IGBT.

This eliminates most of the explosion faults.

EO failures are usually caused by problems with the detection circuit.

First, the voltage detection circuit. The PC version automatically detects whether the home voltage is normal, for example, 230V higher or lower than 200V, and it will show a normal fault**.

Second, the current detection circuit. The current detection circuit is mainly to detect whether the current on the output high voltage side is normal. Circuits are usually formed by several large resistors connected in series.

3. Temperature detection circuit. The temperature detection circuit is mainly to detect the temperature of the furnace surface, or the temperature of the power tube. When the temperature is too high, it automatically protects the shutdown.

Fourth, start the vibrating soup circuit. When the starting oscillation circuit is faulty, it is the same as not putting the pot to alarm, and the oscillation circuit is faulty, relatively speaking, it is very difficult to repair.

The power tube is broken, try another one. If it doesn't work, there is a problem with the sensor, try applying some heat dissipation glue.

Internal circuit faults are mostly due to the large resistance resistance in the overvoltage protection circuit.

The internal circuit of the E0 is faulty, so send it for after-sales repair.

Supor induction cooker is guaranteed for several years.
