How to repair Joyoung induction cooker display E3?

Joyoung induction cooker.

The display of e3 indicates that the voltage is too high, and the induction cooker is overvoltage protected.

The following is the Joyoung induction cooker fault table:

1. E0 internal circuit failure.

2. E1 function light flashes, the alarm is not put in the pot or the pot is too small3. E2 is overheated in the machine, the tuyere is blocked, the fan does not rotate, and the IGBT temperature sensor.

Open circuit or short circuit.

4. The E3 voltage is too high.

5. The E4 voltage is too low.

6. E5 ceramic plate temperature sensor is open-circuited.

7. The E6 pot is dry-burned, the temperature of the pot is too high, and the temperature sensor of the ceramic plate is short-circuited.

8. The temperature of the E7 reel is too high.

7. E8 is damp or dirty inside.

E3 means that when the grid voltage is too high and the voltage returns to normal, it will automatically exit the fault alarm state and restore the original working state.

Hello, the grid voltage is too high to show "e3", the grid voltage is too low to show "e4", please try it after half an hour, when the voltage returns to normal you can use.

What to do if the induction cooker shows e3.

Minor glitches Find a master to repair.

It is recommended that the landlord go to Joyoung's official website to find Joyoung's after-sales ** consultation, or find the after-sales maintenance point in your area**, and the after-sales personnel will be more professional.

Check for a few non-inductive capacitors and key leakage.

Joyoung induction cooker shows e3: The grid voltage is too high.

This is applicable to all models of Joyoung induction cooker (stove).

Joyoung induction cooker is a common problem, and other induction cookers are used well. Joyoung induction cooker often displays E3. There are also Joyoung induction cookers that can't use good Mrs. brand pots, and other induction cookers can't be used.

Summary. 1. First of all, we should test whether the power grid voltage of the user's home is normal, and the range of our induction cooker power grid is - the upper limit is 265V 275V, and the lower limit is 150V 170V (the voltage range of the induction cooker will be wider after 07). 2. If the power grid normally appears E3, it is a defective high-voltage protection circuit, which is mostly caused by the change of high-voltage resistance (partial voltage) (if E3 is still displayed, please go to the maintenance network for inspection).

3. (180V, 250V) check whether D91, D92, R91, etc. are normal, measure whether the voltage of the CPU 15 pin is about 3 4V (the size of the R92 resistance value can be changed according to the actual situation), and check whether the voltage of 5V and 15V is normal.

1. First of all, we should test whether the power grid voltage of the user's home is normal, and the satisfaction of our induction cooker power grid is 265v 275V, and the lower limit of the return judgment is 150V 170V (the voltage range of the induction cooker after 07 years will be wider). 2. If the power grid normally appears E3, it is a defective high-voltage protection circuit, which is mostly caused by the change of high-voltage resistance (partial voltage) (if E3 is still displayed, please go to the maintenance network for inspection). 3. (180V, 250V) check whether D91, D92, R91, etc. are normal, and the voltage of the 15 pin of the CPU is about 3 4V (the size of the R92 resistance value can be changed according to the actual situation), and check whether the voltage of 5V and 15V is normal.

Joyoung induction cooker E3 failure may be caused by the following reasons:

1.The power cord is in poor contact or damaged.

2.The internal circuit of the induction cooker is faulty.

3.The induction cooker control board is faulty.

4.Induction cooker sensor malfunction.

For the above faults, you can try the following maintenance methods:

1.Check that the power cord is in good contact and needs to be replaced if damaged.

2.Check whether the internal circuit of the furnace is loose or short-circuited, and reconnect or replace the circuit board if necessary.

3.Check whether the control board of the induction cooker is damaged or faulty, and replace the control board if necessary.

4.Check whether the induction cooker sensor is damaged or malfunctioning, and replace the sensor if necessary.

If the above methods cannot solve the problem, it is recommended to contact Joyoung after-sales service center for repair or replacement.
