In summary, microwave energy emitted from a microwave that is turned on and running with nothing in it can have an effect on nearby electronics, particularly those that operate on the 2.4 GHz band. This is due to potential leakage from the microwave, which can vary depending on the quality of the shielding. While the leakage may not be harmful to humans, it can cause interference for sensitive electronics. It is important to read the User's Guide or Owner's Manual of a microwave to understand the potential risks of running it without a load.

Can the microwaves emitted from a microwave that is turned on and running with nothing in it have an effect on nearby electronics, i.e. computers, cell phones, surround sound receivers?

Yes, microwave energy can leak out of your oven and interfere with nearby electronics. I've found that the electronics most affected are those that use the 2.4 GHz band, which is where the oven operates. 802.11 wireless cards and cordless phones are especially susceptible.

I've measured leakage from ovens, and it can be all over the map, depending on the quality of the shielding (especially around the door). Running the oven empty probably means that even more energy is leaking out.

There probably is small leakage, but not enough to harm us. The shielding on the door is usually enough to stop enough from leaking out. But for sensitive electronics, the situation is otherwise.

Most microwave ovens have a warning in their User's Guides about not running the oven without a load (something to heat). I think it can cause the magnetron to overheat maybe? Or maybe it can cause too high emissions as you are implying. If you can find a User's Guide or Owner's Manual to an oven, it will probably say. Maybe you can find one online at a manufacturer's website.
 

Related to Microwaves with Nothing Inside

1. What are "Microwaves with Nothing Inside"?

Microwaves with Nothing Inside (MWNI) are a type of microwave oven that do not contain a rotating dish or turntable inside. Instead, the microwaves are distributed evenly throughout the interior of the oven using a stirrer or fan, allowing for more even heating of food.

2. How do MWNI ovens work?

MWNI ovens work by using a stirrer or fan to distribute microwave energy evenly throughout the interior of the oven. This allows for more even heating of food without the need for a rotating dish or turntable.

3. What are the benefits of using a MWNI oven?

One of the main benefits of using a MWNI oven is more even heating of food. This can lead to better cooking results and less need for stirring or rotating food during cooking. Additionally, MWNI ovens tend to be more compact and have a larger interior capacity compared to traditional microwave ovens.

4. Are there any downsides to using a MWNI oven?

One potential downside of using a MWNI oven is that some foods, such as larger or heavier items, may not cook as evenly without a rotating dish or turntable. Additionally, the lack of a rotating dish may limit the types of cooking and baking dishes that can be used in the oven.

5. Can any recipe be used in a MWNI oven?

Most recipes can be used in a MWNI oven, but it is important to follow the cooking instructions and make any necessary adjustments for the lack of a rotating dish. It may also be helpful to use smaller or lighter dishes to ensure more even heating of food.
