Is it dangerous if a microwave works but doesn't heat?

With the development of science and technology in modern society, every household has more small household appliances. Our lives have become much more convenient, but how do we solve problems with these home appliances? Now every household has a microwave oven, but microwave ovens often have problems, such as: What if the microwave oven works but does not heat? What is the problem? Next, please follow the editor to see how to solve it.

There are three main reasons why the microwave oven cannot heat: 1. The voltage is too low. 2. The microwave oven's high-voltage fuse is broken. 3. Caused by leakage of high-voltage diode. When the voltage is lower than 187V, the microwave oven will not heat. Because the high-voltage transformer in the microwave oven must be higher than 187V to work properly, it is recommended to avoid peak electricity consumption when the voltage is lower. To eliminate the first cause, you can use a multimeter to troubleshoot the microwave oven in order to solve the problem more quickly.

The specific steps are as follows:

1. Troubleshooting for non-heating: Disassemble the microwave oven casing, first discharge the voltage of the high-voltage capacitor, and adjust the multimeter to the R×1kΩ position. Detect components that are more prone to failure. For example: high-voltage fuse, high-voltage transformer, high-voltage capacitor, high-voltage diode, and magnetron. Everyone knows that the main reason why a fuse blows is because of excessive current. When using a multimeter to test, you need to set the multimeter to the R×10kΩ position to test the high-voltage capacitor and high-voltage diode again. It is found that the high-voltage diode has resistance in both the forward and reverse directions. Under normal circumstances, the forward resistance is about 150kΩ and the reverse resistance is infinite. Therefore, it is judged that the high-voltage diode is leaking. The high-voltage diode and fuse are replaced to eliminate the fault.

2. How to replace the microwave oven fuse: First, know the location of the fuse: remove the outer shell of the induction cooker, and the fuse of the induction cooker is located at the bottom between the transformer and the fan. (Open the outer shell of the microwave oven and follow the power cord. You will find a "small plastic box" which contains the fuse.

) Again, remove the fuse with the plastic casing and replace it with a fuse of the same specification to test the machine. It is recommended to place a bowl of water on the turntable.

In summary, the above is my answer to the problem of the microwave working but not heating. Through the editor's introduction, everyone can solve the problem by themselves according to their own conditions. Be sure to pay attention to safety and prevent explosions and other situations. If it is still usable, just try your best to ensure your own safety and health.
