What can I use a magnetron to do?

The magnetron is partly damaged from sparking that is usually caused when metalic catlery is used even milk parkets with siver lining could damage. In your case the microwave will soon give in and you will have to replace the magnetron.

Sound like a magnetron go to bad; here are the steps we took to replace it

Warning: You are not an electrician or repairman, following steps are from my experience. You should be careful while handling capacitor and other parts.

Unplug Microwave at least few hours before
Remove Microwave from above oven range by somebody holding Microwave from ground unscrew the screws from cabinet
Remove top cover of Microwave
Make sure to keep screws correctly in a place you remember what goes where
Make sure capacitor is discharged, GE manual inside Microwave says capacitor will discharge within 30 seconds once it is off. As a precaution check the voltage in capacitor to make sure there is no electricity
Remove other panels around magnetron part
You need to remove lot of connecting wires, should be careful to note down what goes where
If possible take digital photos to refer back when you put everything back together
You may need to remove transformer to easily remove and replace Magnetron. If you can't remove Magnetron easily then remove bottom panel of the Microwave and remove transformer
Now it should be easy to remove magnetron
Replace new magnetron and screw it. We had to put one outside part from old magnetron to new one because new one was missing that. Check to make sure both old and new one are exactly the same
Make sure put all wires properly back
Now put transformer back and screw it
Put capacitor panel in place and screw it
This might be a good time to test the Microwave to make sure it works fine now
Now cover the top panels and start to screw everything
Once everything assembled put the Microwave back above range put screws from top

Hope this helps (remember to rating this free answer).

With all due respect, what are you doing to it?
If you use it with nothing in the cavity, that will kill the magnetron otherwise it will last for years and years.
Very unusual and Bosch is a well respected name.
If there is a probem with the oven, Bosch will replace it so take it up with Bosch.

you have a problem with your magnetron tube, and when the magnetron tube goes bad, the diode almost always goes out with it. you should be able to order a replacement tube from your manufacturers website, if you cant let me know and ill try to help you more.

here are the steps to replace the magnetron tube, if you want to do it yourself that is. if you have a professional do it, it can be pretty costly.

1. Unplug Microwave at least few hours before
2. Remove Microwave from above oven range by somebody holding Microwave from ground unscrew the screws from cabinet
3. Remove top cover of Microwave
4. Make sure to keep screws correctly in a place you remember what goes where
   
5. Make sure capacitor is discharged, GE manual inside Microwave says capacitor will discharge within 30 seconds once it is off. As a precaution check the voltage in capacitor to make sure there is no electricity
   
6. Remove other panels around magnetron part
7. You need to remove lot of connecting wires, should be careful to note down what goes where
   
8. If possible take digital photos to refer back when you put everything back together
   
9. You may need to remove transformer to easily remove and replace Magnetron. If you can't remove Magnetron easily then remove bottom panel of the Microwave and remove transformer
   
10. Now it should be easy to remove magnetron
    
11. Replace new magnetron and screw it. We had to put one outside part from old magnetron to new one because new one was missing that. Check to make sure both old and new one are exactly the same
    
12. Make sure put all wires properly back
    
13. Now put transformer back and screw it
    
14. Put capacitor panel in place and screw it
    
15. This might be a good time to test the Microwave to make sure it works fine now
    
16. Now cover the top panels and start to screw everything
17. Once everything assembled put the Microwave back above range put screws from top

it is mostly fault of magnetron tube inside Microwave. ge has a 10 year warrenty on this part and they can fix it for you for 200$ OR you can order the part from the web and install it yourself. when the magnetron goes out, the diode almost always goes out too so you'll need another of those too. so if you dont want to replace these then buy a new one if not the the steps to repairing are:

1. Unplug Microwave at least few hours before
2. Remove Microwave from above oven range by somebody holding Microwave from ground unscrew the screws from cabinet
3. Remove top cover of Microwave
4. Make sure to keep screws correctly in a place you remember what goes where
   
5. Make sure capacitor is discharged, GE manual inside Microwave says capacitor will discharge within 30 seconds once it is off. As a precaution check the voltage in capacitor to make sure there is no electricity

Hello Case_reimus,

Problem is... (as an old radio-man sees it)
There is NOT a lot more "things" than the
MAGNETRON... to work with...!!

The sole source of ENERGY in the basic Microwave
is the MAGNETRON and if you are in love with the
idea of melting single pats of BUTTER... your NEW MAGNETRON will soon be the "problem"
again ... (excluding convection heat sources).

The nature of the high frequency is such that
less than an approximate cup of water... standard
measurement
TAKING 3 MINUTES to boil... !!

Will allow EXCESS RADIATIONS to be re-absorbed
by the MAGNETRON itself... causing extended
cooking times and PRE-MATURE MAGNETRON failure.

There is no finer type of recycling than to keep a
worthy appliance working beyond it FULL LIFE-CYCLE.

When the microwave is not heating, that means the magnetron is not working. This is what provides the heat to the microwave. I do believe the magnetron has a 10 year warranty.

If you wish to replace it, here is how:

1. Unplug Microwave at least few hours before
2. Remove Microwave from above oven range by somebody holding Microwave from ground unscrew the screws from cabinet
3. Remove top cover of Microwave
4. Make sure to keep screws correctly in a place you remember what goes where

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts, then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

I have an over the oven microwave that blew a magnetron after 4 years. Could be the same thing. It was out of warranty for the free labor, so I took it apart (I'm kind of a geek) and found out the magnetron was gone. Shortening the story: I bought a new magnetron from an online place and replaced it and it works fine. If you have someone replace your magnetron, see if you can get it for free-they have a long warranty on the magnetron ($150 part) and at 5 years, you probably qualify. Rich

If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

You can also order from MicrowaveSvc , they also provide parts.
