Why doesn’t the microwave heat up and how can it be fixed?

In recent days, numerous consumers have expressed their confusion and frustration due to a recurring problem affecting one of the most commonly used household appliances: the microwave. Many people have reported that their microwaves have stopped heating, causing inconvenience and food wastage.

One of the most common reasons why a microwave could stop heating is the magnetron, the component responsible for generating the microwaves that heat the food. This device can fail due to prolonged use, overheating, or manufacturing defects. Once the magnetron stops functioning properly, the appliance loses its heating capability.

Another factor that could explain this problem is the microwave’s thermal fuse. This element acts as a safety measure, protecting the appliance from overheating. If the microwave gets too hot, the fuse melts and cuts off the power supply to the magnetron, preventing the microwave from heating the food. In these cases, it is necessary to replace the fuse for the appliance to start working again.

In addition to the magnetron and the thermal fuse, other components such as diodes and high-voltage capacitors may also be responsible for the problem. A faulty diode can prevent the current from flowing properly to the magnetron, while a damaged capacitor may fail to store and release the energy required for the appliance to function.

Experts advise users not to attempt to repair the microwave themselves, as manipulating electrical components without proper knowledge can be dangerous. Instead, they recommend contacting a specialized technician who can diagnose and solve the problem safely.

Some users have also mentioned that their microwaves have stopped heating due to simpler issues, such as doors that do not close properly or faulty safety latches. In these cases, it may be less costly and quicker to carry out the repair.

The increasing dependence on microwaves in daily life has made any malfunctioning a major inconvenience for consumers. For this reason, it is essential to perform regular maintenance and follow the manufacturer’s recommendations to prolong the appliance’s lifespan and minimize the chances of failure. In case of any malfunction symptoms, seeking help from a professional may be the best way to ensure that the microwave starts operating efficiently and safely again.
