How to Repair E3 Error in Induction Cooker?
This article explains the E3 error in induction cookers, its causes, and how to repair it. It covers the reasons for the E3 error, the role of ADC in microcontroller IC, and how to repair the E0 and E4 errors.
If your induction cooker is displaying an E3 error, it could be due to low or high input AC voltage. The main AC voltage sensing section of the induction cooker has a voltage divider resistor and a capacitor that work together to regulate the voltage. If either of these components is faulty, it can cause an E3 error to appear on the display.
To repair the E3 error, first, check the voltage divider resistor and see if it is open. If so, replace it with a new one. Next, check the capacitor next to the resistor and replace it if it is faulty. Finally, inspect the IN4007 diode in the main AC voltage sensing section and replace it if necessary.
It is also possible that the microcontroller IC socket pin and base have become rusty, which can prevent the ADC pin from receiving voltage and cause the E3 error. In this case, you will need to clean or replace the IC socket to fix the problem.

It is important to note that the E3 error can occur due to other factors as well, such as a faulty ADC in the microcontroller IC, which is responsible for converting analog values into digital values. To determine the exact cause of the E3 error, it is recommended to seek the help of a professional repair service.
In conclusion, the E3 error in an induction cooker can be caused by various factors including low or high input AC voltage, faulty components in the main AC voltage sensing section, and issues with the microcontroller IC’s ADC pin. By following the steps outlined above, you can repair the E3 error and get your induction cooker working properly again.

Frequently Asked Questions about E3 Error in Induction Cooker:
- What is the E3 error in an induction cooker? The E3 error in an induction cooker occurs due to low or high input AC voltage, or due to a problem in the circuit board of the induction cooker.
- What causes the E3 error in an induction cooker? The E3 error in an induction cooker may be caused by an open voltage divider resistor in the main AC voltage sensing section, a faulty capacitor, a faulty IN4007 diode, or a rusty pin in the microcontroller IC.
- What is ADC in a microcontroller IC? ADC in a microcontroller IC stands for Analog-to-Digital Converter, which converts an analog value into a digital value.
- What is the solution to the E3 error in an induction cooker? The E3 error in an induction cooker can be resolved by checking and repairing the high-value resistor, capacitor, and other components in the voltage divider section.
- What should I do if my induction cooker shows an E3 error? If your induction cooker shows an E3 error, you should check the main AC voltage to ensure it is within normal range, and if the error persists, you should repair the induction cooker.
- What is the voltage divider section in an induction cooker? The voltage divider section in an induction cooker is a section that divides the AC voltage to the ADC pin of the microcontroller IC in order to sense low or high voltage.
- Can the E3 error be resolved on its own? The E3 error may be resolved on its own if it is caused by low or high input AC voltage and the main power is returned to normal. If there is a problem with the circuit board, the error will persist and the induction cooker will need to be repaired.
- What are the ADC pins in a microcontroller IC used for? The ADC pins in a microcontroller IC are used to sense low and high voltage in the induction cooker, and to convert analog values into digital values.
- What is the standard for showing the E3 error in an induction cooker? There is no standard for showing the E3 error in an induction cooker, but most manufacturers show the E3 error when the voltage is low.
- How do I check the components in the voltage divider section in an induction cooker? To check the components in the voltage divider section in an induction cooker, you should check the high-value resistor, capacitor, and other components, and repair or replace them if necessary.
Note: These FAQs are general in nature and may not apply to every specific model of the induction cooker. If you are unsure about how to repair your specific model, please consult the manufacturer or professional repair service.
