If only the induction cooker could still be turned on! The fan doesn't turn! Please check that there are 1 or 2 transistors around the fan pins on the circuit board, most of them are caused by damaged transistors, and by the way, check the current limiting resistors behind it.

If the transistor is broken, the resistor should be replaced! If the other buttons are not operable or the induction cooker does not work, it is estimated that the main chip will also have problems! Please describe the faults in detail or troubleshoot them one by one!

Check the two transistors and the resistors first!

If the voltage fan is normal, it is the failure of the induction cooker, and it is recommended to repair it after sale.

Induction cooktops, also known as induction cooktops, are a product of the modern kitchen revolution, which does not require open flames or conduction heating and allows heat to be generated directly at the bottom of the pot, so the thermal efficiency has been greatly improved. It is a kind of high-efficiency and energy-saving cabinetry, which is completely different from all traditional fire-based or fire-free conduction heating kitchenware. An induction cooker is an electric cooking appliance made using the principle of electromagnetic induction heating.

It is composed of high-frequency induction coil (i.e., excitation coil), high-frequency power conversion device, controller and ferromagnetic material pot bottom cooker. When used, an alternating current is introduced into the ** circle, and an alternating magnetic field is generated around the coil, and most of the magnetic field lines of the alternating magnetic field pass through the metal pot body, generating a large number of eddy currents in the bottom of the pot, thereby generating the heat required for cooking. There is no open flame during the heating process, so it is safe and hygienic.

The reason why the induction cooker fan does not rotate is analyzed, and it is eliminated one by one through the investigation method. If the induction cooker can be turned on and running, the fan does not rotate, and the fault lies in the fan circuit and the fan itself. If the induction cooker cannot be turned on and the fan does not rotate, the fault lies in the stabilized voltage power supply of 18 volts, 5 volts, CPU drive, etc.

Check from back to front, step by step.

Why does the induction cooker fan not turn?

1. The fan power supply circuit is faulty. Unplug the fan on the motherboard, hit the multimeter to the DC voltage level, run the induction cooker with power, and use the multimeter to measure whether the fan pins of the motherboard have a voltage of 12V. If there is no voltage, follow the line to check the upper circuit.

2. The fan itself is faulty. If there is a normal voltage output at the pins of the motherboard, it can be concluded that the fan is broken, and try a different fan.

How to repair the induction cooker fan if it does not rotate?

Fault phenomenon: the fan does not rotate (the indicator light is normal). Fault phenomenon analysis: According to the principle of induction cooker, the causes of the fault phenomenon can be basically divided into two situations:

1. If the induction cooker can be heated normally, and the fan does not rotate. The 5V power supply is normal and the 18V power supply is normal. The scope of the fault should be in the fan control circuit and the fan itself.

2. If the induction cooker cannot be heated normally, and the fan does not rotate. It means that the fault mostly occurs on the 18V power supply and single-chip microcomputer.

Fault circuit inference: 5V regulated circuit, 18V regulated circuit, fan circuit.

Maintenance guide: The output voltage of 18V power supply is 18 01V normal when powered on, and the B pole voltage of Q10 (D667) triode is about 0 7V normal when it is turned on. When the CE pole of the transistor D667 is short-circuited with tweezers, the wind pole operates normally.

In this case, it can be inferred that the fault should be a defective triode Q10 (D667). Remove the D667 measurement and find that its BC pole has been opened, and test the machine after replacement to confirm troubleshooting. Remove the fan and measure the winding wire pack with a multimeter, its resistance value is less than the normal value or the open circuit is damaged.

For the wire package that is not too badly damaged, it can be disassembled and repaired by itself.

After removing the wire wrap, a circle to retreat the winding wire layer, when retreating to the scorched short circuit, cut off a section of the short-circuited wire slightly (if the number of short-circuit burned coils is more, it should be lengthened with a wire diameter of 0 1mm high-strength enameled wire according to the length of the total number of burned turns), and then re-twist and weld the wire head, and then wrap the welding head with yellow wax cloth, and then wrap the wire back into the insulating varnish and soak it and bake it for ten years. If the motor winding has been seriously burned, it should be rewound with the same type of wire diameter (wire diameter is 0 1mm, the number of turns is about 5200 turns), or replace it with a new exhaust motor.

1. The connection point between the stator coil and the lead wire of the fan motor is welded: re-welding is sufficient. 2. The winding of the fan motor is damaged

Test the resistance value of the fan with the ohmic gear of the universal meter, if there is an open circuit, a broken wire or a short circuit, etc., it means that the motor has been damaged and should be repaired or replaced in time. 3. After the induction cooker is energized, it is not heated, the fan does not rotate, and the interface circuit inside the microprocessor chip is damaged, so it is necessary to replace the chip or modify the interface circuit in time for emergency treatment. 4. The fan motor is damaged

Test whether the motor and motor are normal, and if the voltage and capacitance are normal, replace the damaged motor. 5. The cooling fan can also be replaced. Additional Information:

Precautions for the use of induction cooker: 1. It is best to use a dry rag immediately after the induction cooker is used to wipe the surface clean, because we will definitely have some residual substances in the process of use, such as vegetable leaves or moisture, etc., often keep the induction cooker clean and store it well, it will feel like new. 2. When using the induction cooker normally, whether you need to cook or need hot pot, you must follow the instructions to do it, you can't just say that you want to hurry, that is, you can cook some noodles as much as possible, which will easily shorten the life of the induction cooker, and you must turn on the fan to cut off the power after use.

3. For example, if you use an induction cooker once, don't use it for too long, not only to increase the burden on the induction cooker, but also to damage the entire electric stove wire.

The induction cooker fan does not rotate! 1.It's possible that the fan blades are stuck with something!

2.The fan is broken! 3.

The control triode of the fan is damaged! 1, 2 two situations, if you are interested, you can solve it yourself! The fan is used to dissipate heat from the internal parts!

Hope to repair it as soon as possible!

At that moment, dozens of guests arrived one after another, and three people wearing square scarves and a Taoist priest came behind, and they walked in, and everyone didn't recognize them. One of them wore a square scarf and said, "That is Mr. Ji Tianyi?"

Ji Tianyi said: "The little brother is." What do you have to say, sir?

The man took out a letter from his sleeve and said, "Brother Ji Wei is very respectful." Ji Tianyi continued, opened it with Xiao Jinxuan and Zhuge Tianshen, and realized that it was Xin Dongzhi, Jin Yu Liu, Guo Tiebi, and Lai Xiashi, and said:

Have a seat. "When the four of them saw that something was going on here, they were going to take their leave. The monk palace pulled him and said:

Four came from afar.

This problem should be that the fan is damaged or the fan wire is not in good contact, causing the fan to stop, you can replace a fan or reconnect it.

If you can't handle it yourself, you can only find a master to deal with it. This fee. It's definitely going to be dozens.

The repair method of the fan does not turn is as follows1. If it is confirmed that it is a socket problem, please plug the electric fan into another wax socket. If it is confirmed that the wire of the fan is broken, replace it with a wire of the same specification.

2. First clean the oil and sludge of the fan motor, and then drip the lubricating oil on the rotating shaft. Runtong sensitive lubricating oil can be car lubricant or sewing oil. You can consult the salesperson before purchasing, and it can be used for fan motors.

3. If the thermal fuse or starting capacitor of the local branch fruit fan motor is damaged, these two parts need to be replaced directly. It is possible to contact for a replacement or pay for the replacement within the warranty period.
