Yes, it is very bad. When you run a microwave oven without any food inside, there is nothing to absorb the microwaves and they build up inside the cooking chamber. Eventually, something has to absorb them and that something is the oven's microwave source-its magnetron. The magnetron isn't good at handling excessive power that returns to it from the cooking chamber and it can be damaged as a result.
In all my years of experimenting with microwave ovens, I've only killed a magnetron once. But then again, I haven't run a microwave oven for more than a minute or two without anything inside it. If the oven works again after cooling down, then you're probably OK. The oven may have thermal interlocks in its microwave source to prevent that source from overheating and becoming a fire hazard. If the oven fails to work after an hour of cooling off, then you're probably out of luck. The magnetron and/or its power supply are likely to be fried and in need of replacement.

What will happen if you turn on a microwave with nothing in it?
the microwave will get really hot
Why do frozen vegetables have to be turned one quarter turn in the microwave after they have cooked for 2 minutes?
Uneven heating by microwaves inside oven. A turntable should help.
Can a microwave damage a credit card?
If you place it inside and turn the oven on, I presume that the card will be damaged.
is this mocrowave safe for children, does the door need to be closed for it to be operated?
Unless the child manages to get inside the microwave and turn it on, it is safe for children. And, yes, the microwave door needs be shut for the microwave to operate.
What is the difference between microwave and stove cooked food?
Microwave energy is electromagnetic (EM) radiation, and microwave ovens use energy at a frequency of about 2450 MHz (2,450 million cycles per second). This energy is in the microwave band of frequencies, hence the term microwave oven. The frequency is a good choice, because it is quite effective in causing dielectric heating in molecules in the food. This is because there are a lot of molecules within the food that will respond to the microwave energy. These molecules, because they have an electric dipole, will attempt to align themselves with the passing electromagnetic wave. They will be trying to turn back and forth at that 2450 MHz, and this generates heat, which warms/cooks the food.
How would you ensure even cooking of vegetables in a microwave?
Give them a turn or stir every couple of minutes to ensure they are cooked all the way through.
What happens if you turn off your xbox360 while game still inside?
nothing.
Why does cheese turn purple if you microwave it?
I have never had cheese turn purple when I microwave it. Sounds like b.s.
Why does cooked vegetables turn brown?
My best guess is that some of the sugar inside the vegetables caramelizes with the heat, turning the vegetables brown.

Is microwave cooked food is healthier than gas cooked food?
The first answer was :- i believe it is no because the microwave uses radiation waves to cook, either way microwave food is already gas pre-cooked.....My answer is :-The above answer is a common error although I simply can't understand why because Microwaves are a type of radio wave and are an electromagnetic wave...they are NOT a type of radiation but are wave like oscillations of electric and magnetic fields.The microwaves used to heat food in microwave ovens work by heating the water in foods at a frequency to optimally heats water molecules. The microwave energy is converted into heat energy of the water molecules, which in turn heat the other molecules in the food. You can not cook dry foods such as rice and pasta without water.
How do you defroast cooked chicken?
with a busen burner. turn it up to full power and watch your chicken (and the house) explode.
