Joyoung induction cooker maintenance points, Joyoung home appliance maintenance points

Moreover, no matter what the fault of the induction cooker, after replacing the components, you must not rush to connect the online disk test machine, otherwise it will cause the igBTT and fuse tube to burn out, or even the rectifier bridge. In the case of no terminal block, the voltage of each point should be tested by power-on, such as 5V, 12V, 20V (some 18V, 22V), and the wave type output of the drive circuit (normal is square wave), and it can also be tested with a digital multimeter 20V file (normal voltage fluctuates). Because the general induction cooker has a pot detection, about 30 seconds, to measure the drive output within 30 seconds of starting, you can turn off and turn on again if you can't see clearly, and then connect to the online disk after the detection is normal.

After the induction cooker is broken, the detection circuit should not suspect that there is a problem with the chip at the beginning (more than 95% of the chips will not fail), even if the chip has a problem, it must be available to the manufacturer that produces the induction cooker, the market cannot buy, and the same model on the market cannot be replaced.

Joyoung induction cooker is a high-tech small household appliance, which uses the principle of electromagnetic induction, which is more convenient, fast, hygienic and energy-saving and environmentally friendly. But if you run into a problem, you need to repair it. The following is an introduction to the maintenance method of Joyoung induction cooker:

1.Power supply problem: First of all, check whether the power supply is normal and whether the plug is loose to ensure the normal power supply.

If the power supply is normal, but the induction cooker still does not work normally, it is possible that the chip, coil and other parts are damaged, and you need to contact a professional for repair. 2.Cleaning issues:

The heat dissipation holes, radiators, cooktops and other parts of the induction cooker should be cleaned frequently, especially after use, the remaining food residues and oil stains should be cleaned in time. 3.Hunger Control Problem:

If there is a problem with temperature regulation, such as unstable temperature and uncontrollable, it can be solved by adjusting the size of the heat dissipation hole and cleaning the dust accumulation. 4.Line Issues:

Problems such as poor line contact and short circuit may also cause the induction cooker to not work properly. In this case, it is necessary to check the power cord, plug interface and other parts to ensure that the line is in good contact. 5.

Ignition problem: If the heat is large or small when the induction cooker is ignited, you can check whether the ignition device is damaged and whether it needs to be replaced. 6.

Display problems: If there is a problem with the display, such as unable to display, incomplete display content, etc., maintenance personnel need to further check the chip, interconnection cable, driver, etc. The above is the introduction of Joyoung induction cooker maintenance methods, we must pay attention to safety during the maintenance process, avoid touching electronic components, if necessary, you can ask professionals to repair.

At the same time, it is necessary to maintain good daily maintenance and timely cleaning in ordinary use to avoid excessive dust and dirt and improve the service life of the induction cooker.

1. Remove the circuit board, power on, and check whether the voltage of the 16th pin of the main control IC (U4) is.

2. If the voltage is normal and the fault is not eliminated, it means that the main control IC itself is damaged.

3. Replace the main control power-on test machine and troubleshoot.

4. If the voltage measured in the first step is abnormal, use a multimeter to check whether D1, 2, R11, R226, Z2, C203 is normal.

5. If the above components are not asked by Yu Pai, then it can be confirmed that the main IC is damaged, and the fault can be eliminated after replacement.

The premise is to find the root cause and solve problems and failures accordingly.

1. E0: internal fault of the circuit.

2. Turn on the machine to check whether the internal cable and reel lead are falling off.

3. Check whether the components on the board are complete, such as the vertical as before (such as the resistance burned black).

4. Check the solder points (virtual soldering, missing soldering, etc.).

5. Touch the CPU, whether the LM339 is too hot (after power-off) 6. First remove the pins at both ends of the wire reel.

7. Check whether 5V and 15V are normal.

8. Whether the voltage of the LM339 pins is normal.

9. Test whether the four high-voltage resistors of the rubber quantity R21 R24 are normal (remove the measurement) 10. Check whether the Q12 Q15 transistor is broken down or open circuit, etc.
