Why doesn't the microwave turn on?

The microwave oven has long become an integral companion of every kitchen. It greatly facilitates the cooking process and is a faithful assistant to the housewife. However, even such an irreplaceable thing can become faulty. You can find out the cause of the breakdown and carry out repairs yourself.

Possible reasons

Household appliances, even high quality ones, sometimes break down. In most cases, faulty parts can be replaced, and the device will work with renewed vigor. Microwaves are no exception.

Termination of operation can be caused by several factors:

• open door;
• malfunctions of batteries;
• transformer malfunction;
• magnetron failure;
• necessary replacement of fuses;
• capacitor replacement;
• setting the wrong mode.

Before carrying out diagnostics and repairs, it is recommended to carefully read the operating instructions. It indicates all the nuances of each selected part, as well as the subtleties when working with the product.

If work is stopped for other reasons, you should contact a household appliance repair specialist.Such salons are present in every city.

Very often it is not difficult to find out, even with a visual inspection, why the microwave suddenly turned off or did not start working at all.

Open door

Microwave ovens emit powerful electromagnetic rays. Therefore, for device safety purposes, they are equipped with several types of locking. One of them is the inability to start with the door open. Therefore, a possible reason that the microwave does not turn on lies precisely in this.

If the microwave does not turn on, first of all you should check the tightness of the door to the body. There remains a small gap between them, which is necessary to contain the rays. If the door moves away from the body, starting the operation becomes impossible. In this case It is recommended to close the door tightly to resume operation.

A possible reason could be loosening of hinges. To restore it, you need to remove the door and replace the hinges with stronger ones. To work, you only need a narrow screwdriver. You can carry out the replacement at home; it is not necessary to contact a service center.

Setting the wrong mode

Such a seemingly insignificant detail, like setting a mode, is of great importance. If selected incorrectly, the food will be heated poorly. For stable operation, you need to choose the right mode.

Battery malfunctions

A possible reason could be lack of voltage. It is necessary to make sure that there is electricity in the remaining areas 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 socket, you can connect other equipment, for example, an electric kettle or a mobile phone charger. If they work, you should look for the cause in the elements of the microwave itself. Melting may occur on the cord, causing the contacts to come off and the current supply to stop. 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 a specialist who works with household appliances.

A possible reason for the stoppage may be a malfunction of the outlet itself. It is recommended to connect other electrical devices for testing. If it is found to be faulty, you must contact an electrician for repair or replacement.
Line overload has a big impact. If several appliances are plugged into the outlet at once, the microwave oven may not start working due to interruptions. To do this, it is advisable to disconnect third-party devices from the network.

Malfunctions in the operation of components

Difficulties in using a microwave oven may be caused by malfunctions of the built-in parts. In case of serious breakdowns, it is recommended to contact service centers to replace old parts and troubleshoot problems.

However, very often the microwave does not turn on due to minor defects. You can identify the cause and eliminate some of them yourself. We'll tell you what and how you can do at home.

Troubleshooting

Replacing fuses

The main task of fuses in the operation of a microwave oven is electrical protection. They may burn out during operation.

Important! Upon inspection, the appearance of blown fuses immediately catches your eye: they are blackened and slightly swollen.

You can replace them yourself. When purchasing, it is important to pay attention to the identity of the new product with the old parts.. You can purchase it in specialized stores or service centers.

Capacitor check

The reason when the microwave oven works but does not produce heat may be a failure of the capacitor.

You can check its performance using a special device - an ohmmeter. The resistance of the arrow indicates its malfunction.

You can carry out repairs yourself after purchasing a new device. Before resuming use, it is recommended to re-check with an ohmmeter.

Reference. The mark on the “infinity” sign indicates that the functions of the capacitor have been restored.

If this is not possible, it is better to contact a specialist.

Transformer check

The transformer is one of the main internal parts of a microwave oven. It processes and transmits incoming voltage.

Interruptions in operation can be caused by burnout of the primary or secondary winding, which is noticeable upon visual inspection. In such a situation, the right solution would be to contact a service center. Trying to replace it yourself may make the situation worse.

Magnetron failure

Magnetron is the most important microwave element. It is included in the executive circuit of the radiation generator. It is a small block with an antenna. It is he who is responsible for heating dishes, emitting special electromagnetic waves. If it malfunctions, the microwave oven may operate, but heating will not occur.

To carry out repairs, it is better to contact specialists.

However, the magnetron can be replaced independently, at home. The new part must completely match the old one. It is important to pay attention to this when purchasing.

To replace, you need to carefully remove the back of the case and find the magnetron. After this, the old part is removed and replaced with a new one. All that remains is to attach the rear back of the case. After completing the steps, check the operation of the microwave.

Attention! All work to replace failed internal appliances should be carried out only after a power outage.

Failure to comply with safety precautions can result in injury and serious harm to human health.

Conclusion

The microwave oven has firmly established its position in the kitchen appliances market. Its failure always comes as a surprise and great disappointment to the owner. You can carry out small diagnostics and replace broken parts yourself using a few simple steps and following safety precautions.
