Sort of rare these go unless it started to arc and smoke!! Most probable failures are high voltage diodes, control electronics.
If you are sure that is your problem then
Remove outer panel and short high voltage capacitor with a jumper wire, then disconnect all wires to magnetron and unscrew the nuts from it and pull out. Check the condition of the rf seal at base of magnetron and inspect waveguide to verify no burn marks.
Also sometimes a mica diffuser will smoke and burn right at the waveguide entrance to the oven cavity. Make sure to note where wires go where. If you put the wires in the wrong places you will get a blown fuze or a nice light show

Hello there,

You are right that the problem is from the magnetron, it is defective and need to be tested and replaced. Since you have a multitester, you will be needing a ohm meter, here are the steps to testing and replacing the magnetron.

To test the magnetron, please follow these steps,

NOTE: Before you test this component, make sure your microwave is unplugged, and that you have discharged the capacitors.

There are two tests to conduct in order to determine whether or not a magnetron has become defective. If you receive results other than what are detailed below, you will have to replace your microwave's magnetron. Each test is described for you here:

TEST 1: Locate your magnetron and label each of the wires attached to it so that you know which wires are to be replaced where. Set your ohmmeter to the lowest resistance scale. Take a resistance measurement between each of the magnetron's terminals by touching each probe to one terminal each. Reverse the probes and take a second resistance measurement. Each measurement should read less than one ohm.

TEST 2: Set your ohmmeter to its highest resistance scale. Touch one of the meter's probes to a magnetron terminal. Touch the other probe to the metal magnetron housing. Take special caution to not touch the two probes together. This could result in an inaccurate reading. This test should produce a reading of infinity - indicating an open circuit.


To replace the magnetron

Have a certified and experienced appliance repair technician examine and replace your magnetron. This task is much too dangerous for the average layman to perform on his own


Hope this was helpful you.

All the best

I HAVE NATIONAL MICROWAVE/CONVECTION OVEN MODEL NN-C781 JF.IT IS NOT TAKING POWER SUPPLY..LOCAL REPAIR SHOP SAYS MAGNETRON IS NOT WORKING...WHERE AND HOW CAN I PROCURE THIS SPARE PART?


You can try MCM electronics, Digikey or Newark as they have replacement magnetrons. Also, replace the high voltage diode that is associated with that magnetron or you will probably burn up your newly acquired magnetron.

Energies associated with magnetrons can be fatal. Know what you are doing prior to replacement.

Hmv9305/01 microwave @ 13months old the magnetron blew, authorized bosch repairman, replaced using bosch magnetron. warranty for 90 days jan of 2011 same problem, why does this happen? should i ditch...


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.

How to replace a electron for a jenn air microwave


maybe you mean MAGNETRON ... replacing the magnetron is not difficult if you are mechanically inclined .. the problem is getting a proper replacement that doesnt cost more than the oven .. there are also other things that can make the magnetron look bad ... diode, capacitor, transformer,triac and thermal switch ... but if you are sure the magnetron is bad then make absolutly sure the power is not connected before doing anything .. the voltage and current inside the microwave can be fatal if its plugged in ... the cover comes off with just a few screws (top sides and back) .. inside you will find the electronics and a fan that blows on the magnetron's fins .. there is a plug at the bottom of the magnetron that just pulls out ... there are 4 bolts at the top that hold the magnetron in place .. you may have to lossen the transformer or other things like panels to make room to remove the magnetron.. observe how the magnetron was oriented and install the new one the same way .. if you are not skilled in this sort of thing then it is far better to get someone to help you that is .. many ham radio operators (general class and above) have at least knowlege of how this works and how to work safely ..

Micro wave won't heat


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Stopped heating


Ok, if the fan and everything else is functional, this will point directly to a failed Magnetron assembly. this device is responsible for the heating process and, if it is not working properly, your microwave will not heat. Simply replacing the Magnetron will fix this issue.

New GE Magnetron. Where does this new HV diode go?


Fixed it. There was a back capacitor fuse (I believe that's what it's called) on the old magnetron. I removed it and put it on the new magnetron. The HV diode is on the big silver capacitor and very easy to replace. I just didn't see it. It was definitely the magnetron and I hope that this new one comes with a warranty for 5 more years.
