a suitable replacement for the original
PGH brings up a good point; I have bought 'exact' replacements that must have been rejects from production since they were mechanically correct but inferior to the original in power, making a lame microwave out of one originally good one.
Unless the unit has a lot of service time, the more likely failure is the diode rectifier that handles the high current & voltage the maggie needs. That's an easier fix and you don't have a crappy microwave afterward.

It's not difficult to replace the magnetron. Only 2 to 4 screws hold it to its bracket (depending on model) and there are only two wires connected to it. The biggest problem sometimes is removing the cover. Many models use security screws to keep people from opening them. Also there are hazardous voltages that may be present even a good while after the unit's been off. But if you can open the oven, make good notes (or take a camera phone picture) about what went where if you have to take off any parts, and exercise some care, you can change the tube yourself.

Are you sure the part you're getting for free is good, and is a suitable replacement for the original?

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 megatron on LG/Goldstar microwave?


Replacing a magnetron (not "megatron", by the way!) is not difficult. In most ovens, it's held in by a few screws (usually 4) and there are two wires connected to terminals on the mag. Often it's harder to get the oven apart than it is to change the part.

However, you shouldn't try replacing a magnetron yourself. There are lethal voltages present under the cover, often for a long while after you've unplugged the appliance. In addition, unless the mag is replaced properly there is a danger of excessive microwave leakage. This is a repair definitely best left for a professional.

But why consider replacing the magnetron at all? It's the costliest part to replace, and you may find it only a little more expensive to buy a new oven. In fact, for small countertop models, the replacement cost is frequently less than that of a new magnetron. And if you're trying to solve a "no heating" symptom, the magnetron may not even be the trouble.

If you are determined to do the job yourself, there are sites online with parts and how-to information. But I strongly advise you not to do it

My microwave does everything except cook. what would the problem be?


If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.

In order to ascertain whether or not you wish to repair the oven, you need to consider the following: 1. The age of the appliance. Is the microwave oven still under a manufacturer warranty. If so, the repair should be performed at no cost to you. If not, you may have to pay for a service all, or attempt the repair on your own to save the cost of labor charges.
2. If you wish to repair yourself, you will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
3. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
4, The magnetron replacement part number for the model you have this question listed under is 8206317. The average cost is about $45-$50. NOTE: This model also has a thermal cut-out (TCO) mounted on the magnetron. The TCO acts as fuse and if blown, will cause the oven to fail as well. You can check the tco by removing it from the circuit and measuring across the terminals. If good, it should read 0 ohms. The part number is 8184951 and generally costs about $25.
You need to decide whether or not the cost of replacement parts and the labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble. Its not a difficult process, but it can be labor intensive to uninstall the oven.
If you have any questions, please post back and let me know. I hope you find this information helpful.
CAUTION: DO NOT operate a microwave oven, with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.

The microwave stopped microwaving, but the clock starts to countdown


Hi, with the MW ovens, there isn't too much to go wrong, and when they do there are three places we check, One the main circuit board, two the Magnetron and three the Power Supply in particular the High Power Diode.
MW's are VERY DANGEROUS to service, as they have a VERY large Capacitor in them which if touched when charged WILL KILL YOU,therefore I usually try and dissuade anyone from DIIYing a MW. Only skilled engineers should undertake repairs i feel.
In any event I would think that your problem is indeed the magnetron/High Power Diode., it usually is.
Please take the Unit to a reputable repair center, now when there ask for a "Quote" before allowing repairs to start. This way you will get an idea of costings, as you see often the replacement costs, like a magnetron can easy cost the repairer $100.00, and the cost of repairs can quickly approach the cost of a New unit, with a warranty... thus when armed with the costings one can then make an informed decision as to what to do,.

Oven will not heat but turnstyle and other features operate ok.Is there a fuse that can be replaced?


several of the GEs i have worked on with your symtoms turned out to be bad magnetrons ... if the magnetron gets too hot then it will go bad .. you can get it really hot by running it without anything in the oven .. but several of the failures were caused by a fan mount failure ... there is a fan that cools the magnetron .. it is mounted on a plastic framework .. if the plastic breaks or distorts then the fan is not aimed in the correct direction .. the air goes around the magnetron instead of thru it and it fails to cool the magnetron ... so in these cases the fan framework was repaired and a new magnetron installed .. often that repair costs more than a new microwave oven .. there are other things that will cause the same trouble .. a high voltage diode, a capacitor, a transformer, a relay and a high temperature cut out switch ... the cutout automatically resets once things cool down but it can go bad .. the cost of some of these things is not high but labor often dictates the repair vs replace decision ... magnetrons cost a lot unless you have connections .. .at any rate you dont want to be powerering the microwave when its taken apart .. with the cover off there is potentially fatal voltage and current avalible by just touching the wrong thing .. ..

I turn it on and everything works but it dont heat up the food. the air and light is on and it turns but it just dont heat up


There are several possible causes, but the usual one is failure of the magnetron tube which makes the microwaves. The tube is replaceable, but it's costly. With labor, the repair is likely to cost more than a new oven. (While it isn't difficult to change the tube - only a few screws and a couple of push-on connections - microwave ovens are best left to professionals. There are lethal voltages present and the chance of microwave leakage if repairs aren't done properly.)

If you want to keep this oven, let a shop diagnose the cause and give you an estimate. Otherwise check the Sunday paper ads for sales. (A retailer here in my city had a 900 watt oven for $50 recently. A new magnetron is at least that.)

Power comes on, but will not heat. can i fix this myself?


This is most likely to be a fault with the Magnetron, this can be an expensive repair & can be a difficult part to replace if you are not experienced with electrical goods. I wolud recommend taking it to a local repair centre & ask for an estimate. Depending on the age & the cost of your microwave when bought, it maybe more economical to buy a new one.

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.

Yes, it could be the Magnetron. If the unit is out of warranty, you can try to remove the rear cover (make sure unit is unplugged) and see if there is a blown fuse in the section that powers the Magetron. They are not too difficult to replace. MCM Electronics sells them and you can call them with your model and they can find a replacement for you will be able to see how much it will cost.
