The microwave is one of the most popular electronic equipment and is often present in any kitchen. But like all household appliances, it has a useful life period and, therefore, it is quite normal that some problems can damage it. Still, some situations can be avoided. We discuss some of them below. If, finally, you cannot solve a problem with your microwave, do not hesitate to hire a professional microwave repair. But before getting into “the situations”, you need to know how a microwave works…
How does a microwave work?
Microwave ovens use microwave radiation that’s where their name comes from, they are electromagnetic waves ranging from 300 Megahertz (MHz) and 30 Gigahertz (GHz), to generate them a magnetron is used that is inside the microwave oven and that in practice causes water molecules that are present in food to rotate and vibrate. These vibrations and rotations of the water molecules produce heat, which is what cooks food, now you know why and how food is heated so quickly in the microwave.
Here are some situations your microwave is malfunctioning:
1. The microwave plate does not rotate
This is perhaps one of the most common problems in microwaves. Normally, this situation can happen because the container is larger than the plate or because it is too heavy. Check both options and, if it is not due to either of these reasons, also check if the plate is correctly placed. In the microwave, there is a rotary motor that is responsible for turning the plate. If after checking that everything is correct and the chainring continues without turning, the most likely cause is that the motor is damaged, so it will be necessary to change it.
2. The microwave does not heat
First of all, check if the container you are using is suitable for heating in the microwave, because, on many occasions, this is the reason why the food stays cold. Still, if you notice that the container is hot, this means that the microwave heats properly. If it does not heat at all, you may have a problem with the magnetron, the power of the diode, the capacitor, or some defect in the door closing.
3. The microwave does not turn on
It may seem like basic advice, but the first thing to check in this case is whether the connection is properly seated. Also, check if the cable is damaged. If you do not find any problems, it is best to take the product to a repair center, as you will most likely need help from a qualified technician, since one of the most common reasons for this situation is that a fuse is defective or the motor or the door closing mechanism has a problem.
4. The microwave produces sparks
Although it seems strange, this is also one of the most common microwave problems. It is caused, in a great part of the occasions, by grease or food stains inside. In this situation, you must unplug the microwave and clean it. If the microwave is still sparking, the problem may be internal, so you will need a support team to take a look at it.
Finally, you should know that it is advisable to repair only those things which you know how to do, do not repair anything that you do not know. Inventing is not part of electrical repairs as the consequences could be fatal.
