Midea induction cooker MC EP192 burns the insurance, what is the reason for the failure?

There are two reasons, either there is a foreign object on the bobbin that short-circuits it, or there are burned components in the circuit that supplies power to the bobbin, so that it cannot be supplied with power if it is short-circuited.

If it is resistive burning, it should be open circuit or become larger, you check the IGBT to see if there is a short circuit in other places

Midea induction cooker is a high-tech kitchen appliance product, which uses electromagnetic induction technology to directly heat the bottom of the pot, which is loved by more and more people. However, in the course of long-term use, some problems will also arise. One of the more common is the failure of Midea's induction cooker fuse.

A fuse is a very small electronic component, which acts as a safety protection element, which can disconnect the circuit in the case of excessive current or short circuit, etc., to prevent the circuit from being overloaded and avoid accidents. Therefore, the fuse width is a very important component in Midea's induction cooker.

However, during use, due to some reasons, such as unstable voltage, temperature increase, excessive current, etc., the fuse may be burned, resulting in Midea's induction cooker not working properly. At this time, we need to disassemble the Midea induction cooker and take out the fuse for inspection and replacement.

The specific steps are as follows:

1.Disassemble the electromagnetic dry balance furnace.

2.Remove the fuse.

After turning on the induction cooker, the fuse can be found. In general, fuses are made up of metal wire, thermosoft plastic, and porcelain tubes.

3.Check the fuse.

Check if the fuse is disconnected, if the fuse has been disconnected, it is burned out and needs to be replaced. If it doesn't, the problem may be with another part.

4.Replace the fuse.

Prepare a fuse of the same specification, then clamp the two ends of the porcelain tube of the fuse with pliers, take out the burned fuse, and install the new fuse.

In short, the failure of Midea's induction cooker fuse is a relatively common problem, but as long as we master the correct operation method, we can easily repair it, prolong the service life of the induction cooker, and avoid greater losses and dangers.

1.Check the viper12 and its accessories again, and replace them if necessary.

2.Replace the thermostat of the detector, there is a possibility that the resistance value will drift.

3.Detect whether the resistance value of the chip resistance 62K on the back side has increased. (Connected to LM339 with 6 pins) 4Intermittent heating is a design flaw in this model of induction cooker, and the 62k patch on it is replaced with a trial.

Check the drive transistor and VR1 adjustable resistor to replace it.

Keep warm function, or retort function.

Check whether the power supply voltage of 305V, 18V and 5V is normal, and whether the rectifier bridge and capacitor are in good condition. and whether the drive transistors S8050 and S8550 are intact. Control whether the voltage of each arm of LM339 is normal.

The fan does not turn. Focus on checking the 18V voltage.

Midea's induction cooker start-up alarm does not heat up the fault treatment.

1. Test whether the voltage of 305V, 18V and 5V is normal, and overhaul it to normal;

2. Several high-power (mostly 1W and 2W) and large resistance (commonly used resistance between 200K-820K) resistors on the circuit board of the induction cooker need to be detected offline one by one, and if the resistance value changes, replace them according to the original parameters;

3, Drive pipe S8550 S8050, need to be checked;

4. The voltage of each pin of LM339 needs to be detected and the faulty components need to be eliminated;

5. Whether the capacitance capacity is normal, whether there is false welding;

6. Use a frying pan made of iron or stainless steel.

Hello! According to what you said, the problem should be that there are components inside your induction cooker that are damaged or broken down.

1. Check whether the fuse tube is damaged, blackened or burst.

2. If there are the above problems, the induction cooker must have a short circuit or breakdown of the components, which will cause the fuse to burn out, resulting in the switch tripping and breaking the circuit.

3. Check whether the rectifier bridge stack, filter capacitor and vibration capacitor are damaged.

4. Check whether the IGBT power tube is damaged.

Overheating burns out the field effect, 300V goes directly to the ground, and finally burns the safety.

It could be that the plug is loose, or your fuse is blown out, or the induction cooker is broken.

There are many reasons for the failure of Midea EP201 induction cooker, such as improper use, aging damage, circuit failure, and so on. The following are a list of several common faults and troubleshooting methods for preparing socks sources:

1.The power cannot be turned on: Check whether the power socket is normal, whether the power cord is plugged in, and whether the power switch is off. If it is normal to be sleepy, then it may be that the power cord is aging or burned out, and the power cord needs to be replaced.

2.Unclear or no display: first check whether the power supply is normal, then check whether there is a suitable pot in the cooking area, and check whether there is any debris in the cooking area. If all of the above is normal, then it is possible that the display is faulty and needs to be replaced with a new one.

3.Unable to heat or heating effect is not good: first check whether the pot is suitable and whether it is placed correctly; Secondly, check whether the ** ring is damaged and whether it is in normal working condition. If all of the above is normal, you can consider replacing the ** ring or replacing the controller.

4.Unstable temperature: It may be that the temperature controller is faulty, and the controller can be replaced; It is also possible that the temperature sensor is faulty and can be replaced with a new one.

In short, Midea EP201 induction cooker troubleshooting needs to be judged and dealt with according to the specific situation to avoid blind maintenance and misoperation leading to greater problems. It is recommended that users read the manual carefully before using the induction cooker, and regularly check whether the functions of the induction cooker are normal to ensure the safety of use.
