Is it normal to be hot and cool in the microwave?

Normal, to put it simply, the microwave oven is by emitting microwaves, so that the water molecules in the food move violently at high speed and friction to generate heat, the original old-fashioned microwave oven is through a rotating reflector at the top to let the microwave move back and forth, and later, that is, most of the current market is a glass disc at the bottom of the rotation, so that the food evenly receives the microwave, to achieve the effect of heating, but there are two points to explain, one is that although the plate is rotating, if the food is placed too biased, it will also lead to uneven heating. The second is that microwave, he has a characteristic, it will reflect when it encounters metal, so if you heat food with a stainless steel plate, there will be a lower part, that is, the side in contact with the plate will heat first, and the upper part will be slower, microwave has a penetrating effect on general ceramics, glass, heat-resistant plastics, wood, bamboo, etc., so it is the best utensil for microwave cooking. Give it a try, that's probably one of the reasons. Hehe.

Normal. Two reasons:

1. The heating time is not enough, microwave oven.

The heated food is uneven, and it will be heated evenly after a little longer;

2. The turntable does not rotate, resulting in uneven heating of food, check whether the turntable motor is rotating.

Abnormal, the microwave oven is mainly heated by friction between ions, which has a certain relationship with time, but there will be no hot and cold at the bottom.

Not normal, it is heated by microwave and should be relatively uniform.

Summary. Check whether the power supply of the microwave oven is normal, if the voltage is too low, that is, when it is lower than 187 volts, it will cause the microwave oven to not heat, because the microwave oven must be higher than 187 volts to operate normally. If you find that the microwave oven does not heat up because the voltage is too low, you can replace the voltmeter, or try to avoid using the microwave oven during the peak electricity consumption period, because many people will use the power supply during the peak electricity consumption period, resulting in the voltage will drop.

If you use a metal container, only the metal container will appear in the microwave, especially the relatively tall stainless steel bowl.

Meals are not heated.

Metal containers cannot be used.

No metal is used.

The microwave is working properly is that the food is not hot.

Check whether the power supply of the microwave oven is normal, if the voltage is too low, it will disturb the alarm, and when the alarm is lower than 187 volts, it will cause the microwave oven not to heat, because the microwave oven must be higher than 187 volts to operate normally. If you find that the micro-bending oven does not heat up because the voltage is too low, you can replace the voltmeter, or try to avoid using the microwave oven during the peak electricity consumption period, because many people will use the power supply during the peak electricity consumption period, resulting in the voltage will drop.

It's just asking you if it can be solved.

I can't repair it myself, so I need to find an after-sales service.

There are two reasons to sell and rush: 1. The heating time is not enough, and the microwave oven heating food is uneven, and the heat will be uniform if the time is a little longer; 2. The turntable does not rotate, resulting in uneven heating of food, check whether the turntable is upgraded and the motor is rotating.

Why the dishes heated in the microwave oven are cold quickly, I think it has nothing to do with the heating method, and it is still determined by the indoor temperature.

First of all, when timing, don't choose enough time at a time, but heat the food in increments. For example, when heating rice, first heat it on medium-high for 3 minutes, and then 2 minutes. Generally, the maximum time is not more than 4 minutes, which has a protective effect on heating containers, especially plastic products, and secondly, the food will not appear half hot and half cold.

Your microwave oven should be a flat-plate model, and most of the flat-plate microwave ovens on the market now have poor heating uniformity, generally the right side is hot and the left side is not hot; It is advisable to heat things up to the right side of the food as much as possible, rather than in the middle.

I'll give you the answer to this question Most of your microwave oven is a new type of microwave oven that doesn't have a turntable Because it doesn't have a turntable, so the microwave has a rotating motor hidden in the furnace to achieve uniform heating Your problem should be that the turntable motor is broken, just replace it It's not a big problem, if you don't understand, ask me again.

It's a style that wants the food to rotate in the oven, and so is mine, because the food is not placed in the middle, and that's what it is. This phenomenon can also be mitigated by placing it in an airtight container.

Well, this is the selective heating of microwaves, which causes the temperature of the heated object to be uneven. I do industrial microwave equipment.

Because you should have put too much, or your microwave oven is broken!

Turn on small, or medium temperature, don't turn on high temperature!

Is your microwave oven flat or rotary?

It's very simple, I'm going to make it simple, and then I'm going to make it more complicated, and I hope you can understand it.

It is a microwave emitted when working in a microwave oven to produce water molecules when it penetrates items containing water molecules"Resonance"Phenomena, violent friction and collision between water molecules occur, so heat is generated, heating water-containing items.

It's complicated.

Microwave ovens mainly emit microwaves (that is, electromagnetic waves with a very short wavelength, but the vibration speed is very fast, about tens of billions of vibrations per second), countless microwaves form a microwave electric field, and the microwave electric field forms an electromagnetic field that vibrates n billion times per second.

This electromagnetic field can cause water in food, polar molecules that don't have the same centers of positive and negative charges, and collide with each other to generate heat (it's too complicated to explain, it's simple, there's a lot of magnets in a bunch of tacks in a box every second, and they collide with each other to generate heat).
