Our microwave oven just quit. Wifey ordered a "magnetron" for me to replace but the appliance store says it should only be replaced by either a qualified microwave technitian or a damned fool. I unfortunately I never went to appliance school. The "heat" is on. Is this something I need to pay someone 100-150 dollars to replace?

my experience has been not so much with a fuse but a device called a thermal cutout. it looks like a diode. Reasons for it to cycle include the circular or cooling fan getting sticky so that heat builds wher it shouldn"t. ihave an old Panasonic that won"t die. ilubed the fan and replaced the cutout twice. It"s quite old now. the newer ones use a turntable whose gearmotor drives are practically unrepairable. they cost aprox 3/4 of what a new mw does.

I have had magnetrons burn out - they are nothing more that a filament in a specially designed envelope. They are not difficult to replace, but like the guys said, make sure those capacitors are fully discharged, and the plug is unplugghed! When you get in there, it will probably be pretty obvious how to replace.

Still under warranty and you have to do the labor?

Yeah, the unit is 8 years old but my wife checked with them and theyre sending us a magnetron gratis. Labor wasn,t even discussed but you make a good point. how can I get them to spring for the labor, I wonder?

why replace expensive parts in a microwave oven? it's a lots cheaper to replace the whole oven. i bought mine about 4 years ago and now the prices are even cheaper. almost everything is made disposable now.

There is a high voltage diode that goes bad in those ovens.

If that diode goes bad they will stop heating and the oven had a different hum when it went bad on this one.

I will admit I have only worked on one but it is still working and I doubt you need a magnetron.

This my 2 cents worth.

Open up the cover and see if there is a fuse on the line voltage wiring somewhere. Mom and Dad had an old, high wattage one that worked great til it just quit one day about 6 years ago. Dad went out and bought a new one to replace it and has always hated it. Why he hung onto the old one is anybodies guess but he did. About a year ago we were cleaning out under the shed and out of curiousity he pulled the cover before throwing it in the scrap bin. There, staring him in the face, was a fuse. The clips holding it had some corrosion on them so he cleaned them up and replaced the fuse and it"s once again working like a new one. Well according to him alot better than the new one that took twice as long to get anything warm.

...but... stay away from the cheapie $50-$100 units at Wallieworld, etc. They are designed to last exactly one year and 1 minute. Spend a little more and get a real appliance.

They sure do have some HEAVY DUTY magnets in those microwaves. Handy for pickin' up roofin'
nails and such!

I agree with the others.. just get a new oven.


I've got electronic experience, and I've replaced a few in my time.. but was not fond of it. these were older units.. like 'radarange' (amana).. etc.... Do discharge the caps.

Many other repairs I've seen were thermal fuses.. or door safeties.. etc..

how do you discharge the caps? Couldn't I check and, if need be, replace the fuse without discharging the capacitor?

Yes.. if it is just a fuse ( ceramic cased ).or a thermal fuse.. ( metal cased ). or a door switch.. yes.. you could repalce those if you were carefull not to touch anything conductive inthere.. problem is.. it is very easy to do.

I made my own discharger.. it's not much more than an insulated probe with a wire hhooked to a gator clip. Wire is made from 8mm copepr core spark plug wire, and i have a power resistor inline so that it does not discharge all at once.

I clip the gator clip to ground then i probe all the hot spots I have a seperate probe with a neon lamp init that I use to check for power.. etc..

Listen to Soundguy... it's advice to LIVE by... discharge the "HV cap" before sticking your pinkies in there. Sort of like a DEFIBULATOR, if you don't!

Having repaired Microwave Ovens for years, the likelihood of the Magnetron being bad is slim. Most common problem, is the "in-line" fuse. Next, would be the door switches.

I would agree, I think the wife must want a new microwave as she keeps trying to kill this one. It isn't even a high dollar one, just a little Samsung with a turntable. One of these days she will probably succeed in killing it, but am on the 4th fuse and all works fine.

Hi Brad,

Wal-mart, Best Buy, Fry's, sell a new magnetron for under $100 installed. Such a deal!

I replaced one an old 800 watt Panasonic and it went OK. I happened to be standing right by it when it went Flash-Ka-Pow. I was very careful to discharge the caps and short everything to ground. I would never do it again because the prices have come down so far that it isn't worth it. In addition you can get rid of all the old bacon grease that had collected just by throwing it in the trash and putting a new one in it's place.

The magnatron was $60 at that time but I have noticed that they are much cheaper at Electronixonline.com.

No longer allowed to throw MWs, TVs, stereos, etc in the trash in California. They can be turned into a collection facility for free, so far. Now there is a state $10 "disposal charge" on that sort of stuff when buying new.

Not if you were trained in radar repair like me. Same circuit but ONLY about 15000 volts. Could be a lot of things other than magnetron. Like a fuze. Make danged sure that it is unpluged and those capacitors are discharged. Is a mistake to repair...just buy a new one, or only 10 to 20 bucks at any yard sale. So many litle screws atc. you will regret it.

For that price you can buy your choice of a dozen new microwaves with many new features. Besides the magnetron may not be the problem. Could be power supply or more likely the controller.
