4. The high-power resistance of the synchronous circuit is damaged or deteriorated, resulting in abnormal detection circuits;

5. The PWM pulse signal is abnormal and the pot is not checked;

6. The long line is moldy and rusty, which will lead to poor contact and will also lead to non-inspection of the pot;

7. The microprocessor MCU is damaged.

The induction cooker shows E0, which is usually a failure to check the pot. The possible reasons are roughly as follows: 1. The detection resistance at the bottom of the wire reel and the IGBT temperature detection resistor are damaged, 2. The main voltage is too low due to the poor filter capacitor of a solder joint at the bottom of the motherboard, so that the voltage detected by the synchronous circuit is abnormal.

4. The high-power resistance of the synchronous circuit is damaged or deteriorated (330K, 470K or 820K resistance), resulting in abnormal detection circuits, (Midea induction cooker case: R29 3901 chip resistance breakdown is disassembled and replaced with OK), adjustable resistance (maximum) 500 ohms; d1;D125, PWM pulse signal is abnormal and the pot is not checked. Focus on checking the peripheral components of the synchronous circuit (LM339, such as:

Tapering capacitor (2A222J)), PWM drive pulse loop (between R12 and IGBT control pole, pay special attention to C9 and C10) 6. Mildew and rust of the long row wire will cause bad contact and unchecked pot. 7. The leakage of a 1kV porcelain capacitor of the pot inspection circuit causes the failure to inspect the pot 8. The microprocessor MCU is damaged.

You have to check what is the fault ** represented by e0, which is on the manual of the general induction cooker, under normal circumstances, e0 represents no pot, no pot, and generally it is an internal circuit problem of the induction cooker.

If you repair it yourself, it is very troublesome, it is recommended to check the sampling resistance of the pot inspection circuit, if there is a warranty, send it to the warranty.

The maintenance method when the induction cooker appears E0: The ceramic plate is very convenient to clean. 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.

Add e0**, lack of e5, e6, e9**, e0 means internal fault, e4 means power supply undervoltage overvoltage, digital tube display fault** and eliminate the old lady induction cooker maintenance **table no pot e1 every 3 seconds.

Go to the maintenance department during the free period. When it expires, trade in the old one.

e0** is not detectable pot. There are the following reasons for the failure of the pot detection circuit:

1. The secondary coil of the current transformer is open and short-circuited.

2. Poor secondary welding of current transformer.

3. Adjustable potentiometer failure.

You didn't talk about specific brands. The induction cooker shows E0, which is usually a failure to check the pot. The possible reasons for this are roughly as follows:

1. The bottom detection resistance of the wire reel and the IGBT temperature detection resistance are damaged.

2. A solder joint at the bottom of the motherboard is soldered;

v The main voltage is too low due to poor filter capacitance, and the voltage detected by the synchronous circuit is abnormal.

4. The high-power resistance of the synchronous circuit is damaged or deteriorated (330K, 470K or 820K resistance), resulting in abnormal acceptance of the detection circuit, (Midea induction cooker case: R29 3901 chip resistance breakdown and dismantle 330 ohms and replace it with OK), adjustable resistance (maximum) 500 ohms; d1; d12

5. The PWM pulse signal is abnormal and the pot is not checked. Focus on checking the synchronous circuit (LM339 pin peripheral components, such as: silk fiber capacitor (2A222J)), PWM drive pulse loop (between R12 and IGBT control pole, pay special attention to C9, C10).

6. Moldy and rusty long rows will cause bad contact and unchecked pots.

7. A 1kV porcelain mask and capacitor leakage of the pot inspection circuit cause non-inspection of the pot.

8. The microprocessor MCU is damaged.

Please check yourself, and if necessary, you can seek a professional to come to deal with the problem.

1. After the power is on, the induction cooker cannot enter the heating state, and the "EO" character displayed on the display screen is fault**. If the component is damaged, it needs to be replaced and repaired.

2. Determine the approximate damage of the fault

1) Open the shell of the induction cooker, in order to ensure the safety of maintenance, remove the ring plate and then carry out maintenance.

2) After power-on, measure the voltage of each pin of the integrated circuit IC3C (LM339), and compare with the normal values listed in the same table, the voltage of the pin and the 14 pins are incorrect.

3) Judging from the measured wax voltage value, the voltage on the pin of the 14-pin signal output terminal of IC3C (LM339) is not right, which may be caused by the abnormal voltage of the pin, and the cause of the abnormal voltage of the pin should be checked first.

3. Find the reason for the abnormal foot voltage, check the core 16 (470K ohms) of the components related to the foot voltage of IC3C (LM339), and find that the forward and reverse resistance values at both ends of C400 (220PF) are close to zero, and the inspection has been broken down and short-circuited.

4. Failure ** is a measure that can be carried out when EO, including shutting down and restarting, and observing whether the components are burned out so that they can be replaced. This is usually due to a short circuit in the internal circuitry. If you don't understand it, it is recommended to go to a special after-sales maintenance service center for maintenance.
