How to Take Apart a Microwave

P3080001_2.JPG
Taking apart microwaves can be dangerous, on this instructable I will show you how to take apart a microwave safely and explain the parts and what you can do with them...

I found this microwave (pictured) lying around in the streets, I took it home with me and took it apart, meanwhile, I decided to make an instructable so you can get an idea of how to take apart a microwave and what its parts can be used for.

What Equipment You Will Need...

You will need tools to take apart a microwave, your bare hands won't work. :-)

  • A set of screw drivers with different shapes and sizes.
  • Wire cutters
  • Pliers
  • Alligator clip
  • Hammer (you don't need this unless something needs to be banged apart)

You might need other types of tools depending on the type of microwave you are going to take apart.

Warning!

Yeah, thats right, taking apart microwave can be very dangerous if you do it improperly...

There is an high voltage capacitor in there that can be still charge and can give out an lethal shock.

Begin Taking Off the Cover

Start taking the top cover off carefully and try avoid touching the wiring!

Discharge the Capacitor

Locate the capacitor, it should be near the big fat chunk of metal, the high voltage transformer. Then get your alligator clips and very carefully touch both terminals of the capacitor...

You may get an loud "SNAP" (which is unlikely) and that indicate the capacitor is discharged, do this a few more time to really make sure the capacitor is discharged..

And you're done! The microwave is safe to gut out!

Gut Out the Microwave

Well, what are you waiting for? Gut the microwave part you want!

What to Do With All of This Stuff?

P3080021.JPG
After you had gutted the microwave, you can find a lot of pretty good stuff, read on through the instructable to fine out what they are and what you could do with them!

The Magnetron

This device, the magnetron, is what heats up our foods...

There is hardly any use for this device, but the magnetron have two very large and powerful ceramic magnets! You can hack the magnetron open and extract the magnets and use them for your other projects.

The High Voltage Transformer

P3080022.JPG
Now this one, is the most dangerous microwave component of all... The high voltage transformer...

The transformer give out 2Kv (2000) AC with outputs of 500mA to 2 amps, far more than enough to instantly kill a person...

The transformer can be put to good use for many high power projects, but most often, people would mod them, and use them to draw arcs for fun... But that is going to be another instructable...

Here is an video of me drawing arcs and lighting sparklers with the microwave transformers.



For some very odd reason, after the sparkler is burnt out, the arcs are much longer, I don't know why it is doing it... Can any body give me an explanation?

Capacitor and Diode

P3080030.JPG
You can use those for some of your high power projects like tesla coils, can crusher, ect.

Line Filter

P3080031.JPG
Those things can be useful if you know what you are doing with them...

Cooling Fan

P3080026.JPG
P3080027.JPG
You can use the fan to cool your self down on a hot day...

I used it as a ventilation fan for my workshop to get rid of all or the solder fumes and other smokes...

Turntable Motor

P3080032.JPG
Those motors spin very slowly, you can add an plate on it rotors and display your things on the table.

Power Relay and Light Bulb

P3080035.JPG
You can use the relay for heavy load switching and if the light bulb still works, you can save it as an replacement bulb for other microwaves.

Bell and Timers

P3080034.JPG
You could use them as a timer for something?

Thermal Fuses

P3080033.JPG
Sometimes, you can find an thermal fuse(s) in a microwave - often found near the magnetron. They are used to break the circuit from the mains if the magnetron overheats...

Safety Switches

P3080028.JPG
The safety switches can be found near the door. You can use it for safety on your other projects or possibly build a beam robot with it...

Heating Tubes

P3080025.JPG
Very strangely, my microwave has two quartz halogen heater tubes.

If you have those tubes, you could use it to make your own heater, or you can salvage the tubes for the nichrome wire (heating element) and use it for some of your other experiments...

The End

Well, I hope you find this instructable helpful!
