How to use this microwave oven. Why is it not responding when I press the menu after powering it on?

**Can't see clearly, looks like a touch screen.

When the microwave oven fails, you should first look at it if it is ** malfunctioning, the most common problem is the button, but if there is no problem with the button, it may be that there is a problem inside the microwave oven, usually the line inside is faulty, as follows:

1. The most prone to failure of the microwave oven is the button, if the button is used for a long time, the internal joint may be loose or broken, so it is easy to contact the poor or simply unable to press the connection place. There is a tool to open the button after checking and soldering again.

2. You can see if the power connection of the microwave oven is correct, if the power connection is incorrect, the button will not respond, we can try to plug in the power again. Make sure the power cord is not damaged. If it is damaged, leakage will also cause the microwave oven to not respond no matter how much you press it.

If the cord is damaged, you can replace it with a new one.

3. The failure of the microwave oven may also be caused by the failure of the internal electric board, in this case, the line contact between the electric board and the panel inside the microwave oven may become poor, so you can carefully check the circuit and reconnect. If the fault is caused by the desoldering of the circuit board, it can be sent to the repair shop for repair. If the repair is not good, it is best to replace the circuit board with a new one directly.

4. If the microwave oven does not respond, it is possible that the line connected to the turntable is broken, generally because the microwave oven has been used for a long time, and there are some circuit breaks caused by aging inside. This situation is more dangerous, because the wiring is broken, but the microwave oven will still heat up, so it is easy to cause some more serious situations. Therefore, in this case, you must turn off the power supply in time and send the microwave oven for repair.

Don't worry if the microwave oven doesn't respond to it, you can see where the problem is**, if the problem is relatively small, you can try to solve it yourself.

Summary. 1. The main reasons for the microwave oven microwave plug-in failure (no heating) are: bad control board, bad high-voltage transformer, damaged high-voltage transformer fuse, bad high-voltage capacitor, bad magnetron, bad high-voltage diode, bad gated microswitch.

2. The maintenance method of microwave oven microwave is not heated: check whether the display is normal, if normal, the power supply. If there is no response at all after the microwave oven is plugged in, it means that the power supply part is faulty, and first check whether the socket is wiped.

Whether there is electricity, if there is electricity, there is no response, it should be that there is a fuse in the Midea microwave oven that is broken. Or maybe the transformer burned. You can open it and check it out.

The microwave oven plugged in the power supply does not light up, and the reasons are as follows: 1. There is no external power supply (the external power supply is not powered, and the microwave oven is not powered, which is a normal phenomenon.) 2. When the external power supply is determined, check whether the microwave oven plug is plugged in.

3. Check whether the microwave oven power indicator is on, and whether there is a ** prompt?

I'm still a little confused, can you be more detailed?

The main reasons for the microwave oven microwave plug-in failure to respond (no heating) are: bad control board, bad high-voltage transformer, damaged high-voltage transformer fuse, bad high-voltage capacitor, bad magnetron, bad high-voltage diode, bad gated microswitch. 2. The maintenance method of microwave oven microwave not heating is:

Check whether the display is normal, if it is normal, it means the power supply. If there is no response at all after the microwave oven is plugged into the power supply, it means that the power supply part is faulty, first check whether the socket is wiped. Whether there is electricity, if there is electricity, there is no response, it should be that there is a fuse in the Midea microwave oven that is broken.

Or maybe the transformer burned. You can open it and check it out. The microwave oven plugged in the power supply does not light up, and the cause analysis is as follows

1. There is no external power supply (no external power supply, no microwave oven is not power, it is a normal phenomenon.) 2. When the external power supply is determined, check whether the microwave oven plug is plugged in. 3. Check whether the microwave oven power indicator is on, and whether there is a ** prompt?

The analysis is as follows: 1. Poor contact: see if the contacts inside are loose, including tin points; When the door is closed, is it closed in place, there will be loose sometimes, and the fuse should be tightened.

2. The keyboard input circuit or monolithic microcomputer input port is faulty: the microwave oven light touch film Mingzen switch is a 4 6 matrix switch, under normal circumstances, when the key is not pressed, the 10 lines between the row and column are not connected to each other, when pressing a key, the two lines corresponding to the key and the column should be connected.

3. If only a few buttons fail, the micro-motion buttons embedded in the interior are aging and out of order, and they can be replaced, and the ones sold (miscellaneous electricity market) are very cheap. If all of them fail, the internal computer board fails, and the entire board is replaced.

4. During the warranty period, find a professional maintenance personnel to start up and check.

When there is no response after the microwave oven is plugged in, the following problems may occur with the positive pin:

Power issue: First make sure the outlet is working properly, you can try plugging in other electrical devices to confirm that the power supply is working. If other electrical appliances are working properly, then it is possible that the power cord or plug of the microwave oven is damaged and needs to be replaced.

Before the fuse problem is buried: A microwave oven will usually have one or more fuses inside it to protect the circuitry. Check that the fuse of the microwave oven is not blown out, and if so, you need to replace it with a new one.

Control panel issues: The microwave oven's control panel may be malfunctioning, preventing it from responding to the power switch. Try pressing a different button on the control panel or resetting the control panel to see if bending responds.

If there is still no response, the control panel may need to be repaired or replaced.

Internal faults: If none of the above methods solve the problem, it may be that there are other faults inside the microwave oven, such as damaged circuit boards, faulty power modules, etc. At this time, it is recommended to contact professional maintenance personnel for overhaul and repair.

Please note that safety is paramount when dealing with any appliance-related issues. If you do not have the relevant technical knowledge and experience, it is recommended to seek professional repair services or consult the manufacturer's customer support department.

It may be the following reasons that cause the Weiwu Haobo oven to not respond after plugging in the power supply:

Poor contact of the power cord: check whether the power cord is plugged in tightly, whether it is damaged or broken;

Burn out the fuse: Check whether the fuse of the microwave oven is burned and the fuse needs to be replaced;

Damaged control board: If the power cord and fuse check are normal, the control board of the microwave oven may be damaged and the control board needs to be replaced.

High-voltage porcelain or transformer failure: If none of the above is a problem, it may be a faulty high-voltage porcelain or transformer in the microwave shaker furnace and needs to be repaired or replaced.

It is recommended that users should find professional and technical personnel for maintenance after self-inspection is fruitless.

Summary. 1. If the power fuse, overheating protector, timing switch and other parts of the microwave oven are damaged, the microwave oven will not be energized;

The microwave oven plugged in and didn't respond, what's going on.

Hello, glad to answer for you.

The main reasons why the microwave oven does not turn on the power are:

1. If the power fuse, overheating protector, timing switch and other parts of the microwave oven are damaged, the microwave oven will not be energized;

2. The power socket is in poor contact, and there may also be no power-on;

3. The fuse degree is blown out, such as the voltage rises suddenly;

4. The fracture of the door hook of the microwave oven will also cause the microwave oven to fail.

5.During the warranty period, find a professional maintenance personnel to start up and check.

The microwave oven plugged in and didn't respond, what's going on.

The main reasons for the failure to respond (not heating) of the microwave oven micro-envy argument wave plug-in are: 1. The control board is bad 2, the high-voltage transformer is bad 3, the high-voltage transformer fuse is damaged 4, the high-voltage capacitor is bad 5, the magnetron is bad 6, the high-voltage diode is bad 7, the door control microswitch is bad, the microwave oven microwave is not heating The maintenance methods are: 1. Check whether the display is normal, if it is normal, the power supply is normal; 2. Press the microwave button to see whether you hear the suction sound of the power breaker, if the power strip is not replaced; 3. Check whether the thermostat is normal, such as normal inspection of magnetron, high-voltage capacitor, high-voltage fuse, high-voltage transformer, high-voltage diode, and gradually replace it if it is not normal; 4. Check whether the door hook and each intermodal block are normal, if the gap is not normal.

What is the reason why the microwave oven does not respond when plugged in? Hello dear! Glad to answer for you, failure analysis:

One. The user's socket is not well connected. Two.

The normal working voltage of the microwave oven is AC 220V, if the working electroosmosis is lower than 180V, the microwave oven can not work normally, and the power supply voltage fluctuates greatly to produce the phenomenon of heating and not heating. Three. The plug in the furnace is not in good contact.

When the weather is cold, the metal plug in the furnace is wide and the socket is retracted, and if the contact is good, it will work normally. Four. If you can't even turn the turntable, then there must be something wrong with the circuit components inside.

Hope it helps!

1. The voltage is too low: the microwave oven has requirements for voltage, if the microwave oven does not heat the first operation is to look at the voltage, when the voltage is lower than 187v, it will cause the microwave oven not to heat, because the microwave oven must be higher than 187v to work normally. Workaround:

Avoid peak hours when using a microwave oven, or replace the voltmeter.

2. High-voltage transformer damage: a small part of the microwave oven is not heated because of the damage of the high-voltage transformer, if you judge whether the high-voltage transformer is broken, the microwave oven is turned on after the light is on but the turntable does not move, and it cannot be heated, it is likely that the high-voltage transformer is broken. Workaround:

Replace the high-voltage transformer.

3. Diode damage: the microwave oven does not heat the diode short circuit caused by the proportion, when your microwave oven is turned on, the light is on, the turntable is also moving, but it just can't be heated, it is likely that the high-voltage diode is broken. You can see if the high-voltage diode is normal, if the result is infinity, it means that the high-voltage diode is broken.

Solution: Replace the high-voltage diode.
