What is the reason for Supor C21S02 A Black C Induction Cooker E3?

Supor induction cooker maintenance failure** safety protection; Pot detection function: During the use of the induction cooker, if the pot is removed, the buzzer will alarm once per second, display EO, power stop output, and no pot will be re-placed on the panel within 30 seconds, and the induction cooker will automatically shut down. ;Material Discomfort Detection Function:

When the induction cooker uses non-ferrous or large uneven pots, the buzzer will alarm once per second, display E0, no power output, and automatically shut down after 30 seconds. ;Small parts detection function: when the induction cooker uses the pot less than 8cm, the buzzer will alarm once per second, display EO, no power output, and automatically shut down in 30 seconds.

Automatic shutdown without keystrokes within two hours: In order to prevent accidents after people leave, the system will be automatically shut down without keystrokes within two hours. Over-temperature protection at the bottom of the pot:

When the induction cooker detects that the temperature at the bottom of the pot is too high, the power output is suspended, and the temperature is lowered before continuing to heat. ;High voltage protection function: when the induction cooker detects that the input voltage exceeds 270V, E3 will be displayed, and the power output will be suspended, and the heating will continue after the voltage is normal.

Low voltage protection function: when the induction cooker detects that the input voltage is lower than 170V, E4 will be displayed, and the power output will be suspended, and the heating will continue after the voltage is normal. ;Power tube over-temperature protection:

When the induction cooker detects that the temperature of the power tube is too high, the power output is suspended and the temperature is lowered before continuing to heat. ;Anti-interference protection: When the induction cooker detects that the instantaneous input voltage is over 330V, the power output will be suspended, and the heating will be continued after the voltage is normal.

Sensor detection function: when the induction cooker detects an open circuit or short circuit of the power tube sensor, it will display E1 and will not output power; When the induction cooker detects an open circuit or a short circuit in the furnace surface sensor, it displays E2 and does not output power.

1--Supor C19S04-A-TD0501T, display E4 after booting: motherboard R256 resistor 470K open circuit. 2--Supor C21A01-TD0525T has no response after starting, check the breakdown of D902 rectifier tube.

3--Supor C21S02 displays E2 after 30 seconds, and the temperature sensor of the power measuring tube is open, and it is normal after replacement. 4--Supor 19s01-a shows e1Check R28 deterioration.

6--Supor C21A01 induction cooker has no response after starting, check the 15V voltage, check the power supply side plate 2m starting resistance open circuit. 7--Supor C21S02-A (Black C)-TD0501CT, E1 is displayed after start-up, the resistance value of the resistance R28 is increased to 1000K, in fact, it is 820K, after the replacement of the Supor C19S07-A-SDBS01-190, the light is on after the start-up, and the pot is not checked, and the R51 resistance is increased to 520K, and the induction cooker of the Supor C16BS is turned on after the change, and the indicator light is on alarm, not heated--R473 and R551, The resistance value is 32K and the change to 75K 10-Supor C21S12-A intermittent heating occurs, and the 4UF capacitor is added to 8UF after OK. Or cut off the R55 synchronous resistor 180K output pin, and directly lead to the J19 input with the wire, and remove the J19 flying wire.

11-Supor C21A01-B-DL02-A0 This motherboard E0 is 10K resistor bad. 12-Supor C19S05-A appears E2, and a resistance of about 200-300K is on the thermistor. Supor induction cooker common faults**E0 internal circuit faultsE1No pots or pans are not suitable for induction cookerE2 IGBT power tube overheating protectionE3 overload protection (generally voltage higher than 253V), E4 undervoltage protection (generally voltage lower than 175V), E5 sensor open circuit, E6 furnace surface temperature overheating protection.

Overload protection (generally higher than 253V).

The induction cooker shows E3 because the connected voltage is too high. Induction cooktops support a wide voltage range and can operate between 90 and 270 V.

There are three scenarios for the possibility of an overvoltage leading to E3, and how to fix it:

1. The voltage at home is indeed high, which is unlikely. And it's good to judge whether other major appliances at home can work normally.

2. The voltage detection circuit is faulty, which needs to be sent for repair.

3. When the machine enters the water, use a hair dryer or take it to the window to bask in the sun.

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.

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.

Pro-Supor induction cooker E0 solution: 1. Supor induction cooker thermal abnormal treatment:

The temperature rise of the door control tube is too high: This fault is mainly manifested as the induction cooker stops heating after working for a period of time, and the alarm sound or the door control tube overtemperature fault**, and then automatically turns into standby. Check whether the fan is running normally, and check Q204, Q205, D262 and the fan if not.

Pay attention to whether the air inlet and exhaust channels of the chassis are unblocked, and whether the door control pipe heat sink is attached to the oil stain. If the fan is functioning properly, check the door control excitation circuitry. The main thing is to check whether the leakage current of ZD201 is too large, whether the performance of Q4 and Q6 is normal (it is good to replace it), and whether +18V is low.

2. Cleaning method when E0 appears in Supor induction cooker: It is very convenient to clean the ceramic plate. If it's a slight dirt, wipe it with a soft, damp cloth.

If it is oily dirt, wipe it with a soft, damp cloth with a small amount of toothpaste or mild detergent while the cooker is hot, at this time be careful to burn your hands, and then wipe with a soft, damp cloth until no residue remains. The shell can be cleaned with a general neutral detergent. Keep the bottom of the pot clean every time you use it, don't dry burn, and wipe it with toothpaste or detergent crystals when it changes color.

When shutting down, you need to wait for the fan to stop completely before unplugging the power. 3. If it is not heated, then you need to shut down the induction cooker, and then restart it to see if the fault is automatically eliminated. If you still can't use the induction cooker normally after turning it on, you need to check whether the components on the porcelain plate of the induction cooker are the same as the original, and see if the electromagnetic components are burned.

If this happens, we need to replace an electromagnetic component. 4. If the induction cooker indicator light is not lit, first of all, we should take a look at the surrounding environment, such as whether the plug has fallen off, or whether the fuse has been burned, and then look at whether the pot used is suitable for the use of the induction cooker, whether it is placed in the right position, etc., these can help you solve the fault that the power indicator light is not lit, and there is a situation, that is, the internal parts are broken, and at this time, you can only find professionals to help repair it. Hope mine can help you <>
