It could, althought it may just be from the high-voltage power supply working correctly.

How does a microwave work?
A microwave oven heats food in a process called dielectric heating. The molecules in the food, primarily water molecules, are polar molecules - meaning they have both a positive and a negative pole due to the distribution of positive and negative charges on the atoms. When they are subjected to microwaves, the molecules rotate as to align themselves with the electromagnetic field, much like a compass aligning itself with the magnetic field of the Earth. Microwave ovens alternate the electromagnetic field to reverse the polarity, causing the molecules to then rotate the other way. Using the compass analogy, imagine taking a magnet and doing circles around the compass; the needle goes crazy. This excited rotation of (mostly) water molecules generates molecular friction with other surrounding excited molecules, generating heat.A common misconception is that the molecules have resonance with the particular frequency used by a microwave oven; ovens that use different frequencies can cook just as efficiently. Another misconception regards the safety of microwave ovens and their radiation. The radiation used in a microwave oven is in the form of radio waves; this is non-ionizing radiation, meaning it is not the same kind of radiation that can cause cancer; that kind of radiation is called ionizing radiation - sunlight and nuclear radiation are examples. Therefore, a microwave oven's radiation cannot cause cancer or other ionizing effects. It's also commonly believed that standing too close to a microwave oven can be harmful, but this is not true. A microwave oven acts like a Faraday cage; the holes in the metal grill that's visible through the oven door are essentially invisible to the radio waves, thanks to their wavelength, so most of the energy is reflected back into the oven. Other sources of microwave radiation, such as cell phones, cannot heat objects like a microwave for two reasons: The relative power of the transmission, and the fact that a microwave oven concentrates nearly all of the energy into the food, whereas a cell phone's transmissions dissipate in all directions, leaving the tiniest fractions of that energy to be absorbed by the body.It heats up and thaws the food that you have placed in the microwave
What safety precautions should you take with a microwave?
With a microwave oven, the major safety precautions unique to the device are to ensure that metals are never placed inside and to prevent any metal item from worming its way through the gasketing and creating a wave path from inside to outside the oven. Check the door interlock from time to time to be sure that the unit shuts off immediately if the door latch is released.Beyond that, the safety precautions are the same as for any small, electrical appliance:Mack sure the cord is in good conditionDon't operate it in water or when wet
Do hamsters explode in the microwave?
Hamsters do explode when placed on a microwave. They explode because the microwaves will make the hamsters heart go faster until they explode. I also heard it was because of radiation but im not realy sure. Correct me if im wrong.
At what distance be human eye placed from TV set?
Between three and four times the diagonal width of the screen (which is the manufacturer's size measurement).
How long do you put water in a microwave to get it to 175 degrees Fahrenheit?
That's going to depend on the cooking power of the microwave oven, the amount of water, the shape of the container it's in, exactly where inside the oven it's placed, or if the oven has a rotating turntable, the speed at which it rotates.
Do wind turbines affect radio and television signals?
If placed in the wrong location, wind turbines can affect radio and television signals.
What is the difference between waves used in microwave ovens and nuclear radiation?
Both microwave radiation and nuclear electromagnetic radiation are members of the same species, but they're as different as babies are from elephants, to wit, microwaves are much, much less powerful than nuclear electromagnetic radiation. Microwave radiation, for instance, makes atoms shift their position (and magnetic fields) very, very quickly. Now the definition of heat is "movement," so the faster anything moves, the "hotter" we say it is. Ergo, something placed in a microwave-radiation-field becomes noticeably "hotter." But comparing microwave and nuclear electromagnetic radiation is like comparing a face-slap to a 20-ton BOMB. Nuclear radiation comes from atomic nuclei, so "nuclear radiation" can strike, penetrate, damage, and even destroy atoms in their path. Big difference, capiche? Huge.We left out the part about nuclear particulate radiation. There is no comparison there. Additionally, nuclear electromagnetic radiation is ionizing radiation while microwave radiation is not.

How does cooking happen in a microwave?
When food is placed inside the microwave oven, the microwave released will 'agitate' the water molecules in the food, which causes heat to be produced, which then cooks the food.
What happen when bread is placed in a microwave oven for 6 days?
nothing
Does metal accidentally placed in a microwave oven become radioactive if it sparks?
no
How a cake will placed in a microwave and what temp?

What is another explanation for the cosmic microwave background?
This is the another theory, which may explain the cosmic microwave background.About 14 billion years ago, you had the "Big bang". Then you had the matter in the form of plasma for about 380,000 years. Till then light was absorbed in your universe. When the matter cooled down enough, light entered in your universe. The cosmic microwave background is in the form of "Glow". That means you are unable to locate the source of light. Cosmic microwave background is not associated with any stars or galaxies. Such type of glow light indicate that the rays are practically parallel. That means the lens of your space telescope perceives the radiation as parallel radiation. So the source of radiation is probably too far, for the astronomical scale also. So the radiation has been coming from other universes, which are too much away from your universe. You may be able to locate the source of radiation with twin space telescopes placed at Lagrangian points 4 and 5. The light is "red shifted" to microwave radiation, means that it has come through the areas of very high gravitational force. The radiation has been coming from all sides means that there are too many sources of light around your universe.
How is radiation used to check welds?
A source of gamma radiation is placed on one side of the weld, and a photographic film is placed on the other. Bubbles and weak points will appear on the film.

What is the difference between microwave oven and bain Marie?
A Bain Marie is a water bath with another section for the food to be cooked to be placed. The water is heated, and the food is placed in the other section then submerged. The heat of the water cooks the food. A Microwave Oven uses radiation energy to heat the water molecules within the food, which in turn heats the food. So to answer, the method by which they cook food is different :) Sources: personal experience, and links in related links
