Galanz induction cooker c203 boots up and shows E0, that place is faulty, say specific point 5

1. The blades of the motor fall off.

Solution: Repair the motor blades.

2. The power supply voltage is too low, causing the motor speed to be too slow.

Solution: Adjust the power supply voltage.

3. The socket connecting the motor to the motherboard falls off.

Solution: Adjust the position of the outlet.

Dude: This problem is an internal circuit failure.

A. Display E0: E0 is a line fault, its detection range is wide, and any component in the whole circuit board will be damaged to indicate E0 fault. Due to its large range, we only analyze a few fragile circuits.

B. Open circuit (breakage) of the reel, c3UF capacitance variable value, as well as R3, R19, R14, R4, R5, R32, R37, R24 synchronous circuit resistors will show E0 when any of them are burned out (open circuit). So the display of e0 should check the above components and spools.

The C A221J capacitance change value will also display E0 without pulse output.

c. Check whether the four triodes of the driving circuit Q1, Q2, Q3 and Q4 and the DW V regulator tube are broken down and short-circuited. (The measurement method uses the diode to measure its voltage drop, which is normally between 650-750, if it is too small or makes a bi, bi sound, it means that it has been damaged).

D. Check whether the inlet electrode of Q1 has 18V voltage to supply it with power. Without 18V voltage here will show E0, to measure the voltage at both ends of R13. If there is one side and one side is not, it is the R13 that is open.

Since e0 can be displayed on the +5V control board, it is certain that the front part is fault-free).

If you are not a professional maintenance person, please do not repair it yourself

Check if there is any virtual soldering, if not, replace the capacitor C4 (222F) next to LM339.

What is the problem with the microwave oven e-3o?

Fault**: E-30 Fault Cause: Circuit fault (IGBT overtemperature).

Fault disguise size: E-30

Fault cause: circuit fault (IGBT overtemperature).

Solution: 1. Check whether the IGBT is faulty and overheated;

2. Check whether the resistance and capacitance of the outer hall are damaged;

3. Check whether the 5V and other voltages on the motherboard are normal, and whether there are other faults in the circuit;

When the machine is turned on, it will appear in a few seconds, less than three seconds, it is the failure of the inverter board, and more than three seconds is the computer board.

Induction cooker display **E2 meaning: voltage is too high, unstable, generally for the local electricity peak period, to judge whether the grid voltage reason, just wait 30-60 minutes before starting, if it can be heated normally, or intermittent heating work, that is, when the voltage is unstable, the induction cooker starts the protection program, the product is not faulty, wait for the voltage to be stable, will not report E2 and intermittent heating phenomenon.

e-0 or 15 minutes timer light flashes The power supply voltage is too low, causing the motor speed to be too slow or the motor blades to fall off.

e-1 or 30 minutes timer light flashing The power supply voltage is too high, causing the motor speed to be too fast or the motor is jamming;

e-2 or 45 minutes timer light flashing The temperature of the radiator inside the machine is too high or the thermostat socket is off;

E-3 or 60 minutes timer light flashes The thermistor is open or damaged, or the connection wire is detached.

Summary of faults in scheme B [original scheme cxxb-imp1 and cxxb-hyp1].

E1 IGBT high-voltage protection, generally not present.

E2 There is no pot, the pot is not placed correctly or the bottom area of the pot is too small. (It occurs more often, and sometimes it is a false alarm.) If E2 is reported for a short period and the heating is restored quickly, it can be considered normal).

The E3 thermistor sensor is open circuit.

E4 Supply Voltage Overvoltage Undervoltage, i.e., exceeding a defined maximum and minimum operating voltage.

E5 The whole machine is overcurrent, and the set current value is exceeded.

The E6 thermistor sensor is short-circuited.

E7 Fan Power Failure.

E8 Dry boiling or over-temperature protection of the pot body (over 260 degrees).

Galanz induction cooker shows E2 fault, E2 means no pot protection. Of course, you must have put the pot on it. This is a fault with an internal "pot inspection circuit". It needs to be sent for repair.

The reasons for this failure are mostly related to the boiler circuit, and the relevant components and their corresponding connecting lines in the pot circuit should be checked to see if there is cracking or poor contact.

Maintenance method. 1) Determine the approximate location of the fault.

Check the voltage between the feet of the microprocessor and the ground, in the state of checking the pot, the maximum is not enough, and when it is normal, it should be greater.

The inspection found that the RPL resistance value of the adjustable resistor became larger to about 21K ohms.

2) Troubleshooting.

Replace a new European adjustable resistor with the same specification and install it, and after confirming that it is correct, the power is turned on, and the work of the induction cooker is restored to normal, and the troubleshooting is done.

Landlord, you're mistaken. We are here in the [mobile phone area], not home appliances.
