Anybody know anything about microwaves?

[Speedy_Gonzales]

Hey...thats not bad thinkin!

where did u buy it ???? some stuff has dates printed on it when it was made

[Rhinohuey]

My dad got it at Best Buy.

Best Buy is much smarter than say wal-mart.......plus their volume is not as high and they can check it out......their warranty is only a month.......if u tell them it has only been less than a month dont tell them an exact day or week .....if u do they will pull up all sales and look to see if u did buy it when u said u did

Microwaves are radio waves.
In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz).
Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars.
When they are absorbed they are converted directly into atomic motion -- heat.
Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics.
Metal reflects microwaves, which is why metal pans do not work well in a microwave oven.

You often hear that microwave ovens cook food "From the inside out."
What does that mean?
Here's an explanation to help make sense of microwave cooking.
Let's say you want to bake a cake in a conventional oven. Normally you would bake a cake at 350 degrees F or so, but let's say you accidentally set the oven at 600 degrees instead of 350.
What is going to happen is that the outside of the cake will burn before the inside even gets warm.
In a conventional oven, the heat has to migrate (by conduction) from the outside of the food toward the middle (See How a Thermos Works for a good explanation of conduction and other heat transfer processes).
You also have dry, hot air on the outside of the food evaporating moisture. So the outside can be crispy and brown (for example, bread forms a crust) while the inside is moist.

In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food.
No heat has to migrate toward the interior by conduction.
There is heat everywhere all at once because the molecules are all excited together.
There are limits, of course.
Radio waves penetrate unevenly in thick pieces of food (they don't make it all the way to the middle), and there are also "hot spots" caused by wave interference, but you get the idea.
The whole heating process is different because you are "exciting atoms" rather than "conducting heat."

In a microwave oven, the air in the oven is at room temperture, so there is no way to form a crust.
That is why microwavable pastries sometimes come with a little sleeve made out of foil and cardboard.
You put the food in the sleeve and then microwave it.
The sleeve reacts to microwave energy by becoming very hot.
This exterior heat lets the crust become crispy as it would in a conventional oven.

Sorry dude but microwaves are microwaves and radiowaves are radiowaves. They are classified by the wavelenghts size (megahertz like you said.) From Ultraviolet, to radio, to micro, to infrared, to visible light that we can see, etc. Theyre all different frequencies but they travel through space the same way just in different size waves. They wouldn't call them two different things if they were the same thing. If you were to classify all of them under one category it would be radiation. Hense nuke the food in the microwave your zapping it with radiation.

just buy the same one from walmart if u can?

[Anthracis]

Buy a replacement...Aren't microwaves like 50 bucks these days?

I think my dad will probably just buy a new one. I just thought I would try to figure it out just for the heck of it.

that would work

Then when you return it just find the most bord teen that works there and could care less if the store gets ripped off.

or do it when they are real busy

i work in a service shop... we repair microwaves but we dont do samsung anymore due to samsung being assholes... anyways i will try and ask someone what the problem is.. but if you call the service 1800 number or w.e and ask the canadians for service they will transfer you to a service center
