Should the Top of a Microwave Get Hot?

When I first purchased my microwave, I was surprised to find that the top of the appliance became hot during use. I couldn’t help but wonder if this was normal. After doing a bit of research, I learned that it is indeed normal for the top of a microwave to get hot while in use. In this article, I will explain why this happens and whether or not you should be concerned about it.

Why does the top of a microwave get hot?

Microwaves work by emitting electromagnetic waves that heat up the food inside. These waves are produced by a magnetron tube located inside the microwave. When the waves are emitted, they bounce off the metal walls and eventually reach the food, causing it to heat up. However, a small percentage of these waves are also absorbed by the metal case, causing it to heat up as well. This is why you may feel heat on the top surface of your microwave.

Is it normal for the top to be hot?

Yes, it is perfectly normal for the top of a microwave to get hot during use. In fact, it is a sign that your microwave is working as it should. The heat on the top surface is simply a byproduct of the energy being generated by the magnetron tube. As long as the heat is not excessive and the microwave is properly ventilated, there is no reason to be concerned.

Should I be worried about the heat?

While it is normal for the top of a microwave to get hot, it is important to ensure that the heat is not excessive. If you notice that the top of your microwave becomes extremely hot to the touch or if you smell burning, it could be a sign of a malfunctioning appliance. In this case, it would be wise to have your microwave checked by a professional technician to ensure it is safe to use.

How can I reduce the heat on the top of my microwave?

If you find that the heat on the top of your microwave is bothersome or if you simply want to minimize it, there are a few things you can do:

Make sure your microwave is properly ventilated. Ensure that there is enough space around the microwave for air to circulate. Avoid placing items on top of the microwave that could block the airflow.

Use the correct power settings. Cooking at higher power levels for longer periods of time can generate more heat. Try reducing the power level or cooking in shorter intervals to minimize the heat produced.

Clean the vents. Over time, dust and debris can accumulate in the vents, hindering proper ventilation. Regularly clean the vents to ensure optimal airflow.

Consider using a microwave cover. A microwave cover can help trap the heat inside the appliance, reducing the amount of heat that is emitted through the top surface.

Conclusion

In conclusion, it is normal for the top of a microwave to get hot during use. This is due to the absorption of electromagnetic waves by the metal case of the appliance. As long as the heat is not excessive and the microwave is properly ventilated, there is no cause for concern. However, if you notice excessive heat or burning odors, it is advisable to have your microwave checked by a professional. By following these tips, you can minimize the heat on the top of your microwave and ensure its optimal performance.
