A microwave has long become an integral companion of every kitchen. She greatly facilitates the cooking process and is a faithful assistant to the hostess. However, even such an irreplaceable thing can become malfunctioning. You can find out the cause of the breakdown and carry out repairs yourself.
Possible reasons
Household appliances, even of high quality, someday fail. In most cases, defective parts can be replaced, and the device will work with renewed vigor. Microwaves are no exception.
The termination of functioning can be caused by several factors:
- open door;
- disturbances in the work of batteries;
- transformer malfunction;
- failure of the magnetron;
- necessary replacement of fuses;
- capacitor replacement;
- setting the wrong mode.
Before carrying out diagnostics and repairs, it is recommended that you carefully read the instruction manual. It shows all the nuances of each selected part, as well as the subtleties when working with the product.
If the work is stopped for other reasons, you should contact a specialist in the repair of household appliances. Such salons are present in every city.
It is often easy to find out even with a visual inspection why the microwave oven suddenly turned off or did not start working at all.
Open door
Microwave ovens emit powerful electromagnetic rays. Therefore, for the safety of the device, they are equipped with several types of locks. One of them is the inability to start with the door open. Therefore, the possible reason that the microwave does not turn on lies precisely in this.
If the microwave oven does not turn on, first of all, check the tightness of the door to the body. Between them remains a small gap necessary to restrain the rays. If the door moves away from the body, the start of operation becomes impossible. In this case close the door tightly to resume operation.
A possible reason could be loosening loops. To restore, you must remove the door and replace the hinges with stronger ones. To work, you need only a narrow screwdriver. You can replace at home, contacting a service center is optional.
Setting the wrong mode
Such a seemingly insignificant trifle as setting the mode is of great importance. If the selection is incorrect, the food will be slightly heated. For stable operation, you need to select the correct mode.
Violations in the work of batteries
A possible cause may be a lack of voltage. You need to make sure that there is electricity in the remaining rooms of the apartment or office. If everything is in order, it is recommended to check the outlet and the kitchen appliance itself.
To check the outlet, you can connect other equipment, for example, an electric kettle or charging from a mobile phone. In the case of their work, the cause should be sought in the elements of the microwave itself. Melting can occur on the cord, because of this the contacts drop off, and the current supply stops. The best option for stable use is to replace the cord. To carry out this procedure, it is better to entrust the microwave oven to the master of work with household appliances.
A possible reason for the termination of work may be a malfunction of the outlet itself. For testing, it is recommended to connect other electrical appliances. If it is found that it has failed, you must contact an electrician for repair or replacement.
The congestion of the line has a great influence. If several appliances are connected to the outlet at once, the microwave oven may not start working due to interruptions. To do this, it is desirable to disconnect third-party devices from the network.
Violations in the operation of components
Difficulties in using the microwave oven may be caused by malfunctioning of the integrated parts. In case of serious damage, it is recommended to contact service centers to replace old parts and troubleshoot.
However, very often the microwave does not turn on due to minor defects. It is possible to identify the cause and eliminate some of them yourself. We will tell you what and how to do it at home.
Troubleshooting
Fuse Replacement
The main objective of microwave fuses is electrical protection. In the process, they can burn out.
Important! Upon examination, the appearance of the blown fuses is immediately evident: they are blackened and slightly swollen.
You can replace them yourself. When buying, it is important to pay attention to the identity of the new product to old parts. You can make the purchase in specialized stores or service centers.
Capacitor check
The reason when the microwave oven works, but does not produce heat, may be the failure of the capacitor.
You can check its performance using a special device - an ohmmeter. The resistance of the arrow indicates its malfunction.
Repair can be carried out independently, after buying a new device. Before resuming operation, it is recommended to re-check with an ohmmeter.
reference. The mark on the "infinity" sign indicates the restoration of the capacitor functions.
If this is not possible, it is better to contact a specialist.
Transformer check
The transformer is one of the main insides of the microwave. He is involved in the processing and transmission of incoming voltage.
Malfunctions can be caused by burnout of the primary or secondary windingthat is noticeable during visual inspection. In such a situation, the right decision would be to contact the service center. Trying to replace yourself can make the situation worse.
Failure of the magnetron
Magnetron - the most important element of the microwave. It enters the executive circuit of the radiation generator. It is a small block with an antenna. It is he who is responsible for heating the dishes, highlighting special electromagnetic waves. In case of malfunction, the microwave oven can work, but heating will not be carried out.
For repairs it is better to contact specialists.
However, the magnetron can be replaced independently, at home. The new part must fully match the old. It is important to pay attention to this when buying.
To replace, carefully remove the back of the case and find the magnetron. After that, the old part is removed and replaced with a new one. It remains to attach the rear back of the case. After completing the steps, check the microwave operation.
Attention! All work on the replacement of failed internal devices should be carried out only after the power supply is cut off.
Failure to follow safety precautions can result in personal injury and serious harm to human health.
Conclusion
The microwave oven has firmly established its position in the market for kitchen appliances. Its failure always becomes a surprise and a great chagrin for the owner. You can conduct a small diagnosis and replace broken parts yourself with a few simple steps and safety precautions.
