SOURCE: Noisy magnatron

First of all, if you press against the right side of the outer cover of the oven, does that lessen the noise? If so, it may be that a rubber cushion on the side of the HV transformer has fallen off.

If it had that hum but was not heating, I would first check the HV rectifier diode.

But since it's cooking, I would say your magnetron is on the way out.

Unless the warranty is about to expire, I'd continue to use it and watch and wait.

SOURCE: GE spacemaker xl1800 and Pop tarts bad mix

it sound to me as if the high voltage diode is shorted. It could be inside the capacitor or out board the cap. The capactor could also be short but this is a rarity. Diodes are a cheep item . repace it and if it don't work its probably the magnatro. good luck.

SOURCE: The magnatron quit - is it worth getting fixed?

Magnatrons rarely go bad.

Check your door safety interlock switches. Do you open the door while the oven is operating?

If yes, you have burned the contacts of the little micro switches to the point that they are not functioning.

When this happens, the oven doesnt know the door is closed and will not turn the magnatron on.

Remove the cover, DONT TOUCH THE SILVER CAN, check the switches for contunity.

The other possibility is the silver can is bad - dont touch it unless and until you undersstand withat it is and what it does. It can be very dangerous.

Replacement parts locally or www.repairclinic.com

Microwave will not heat food


Unless an expensive unit replacing the Magnatron and or Inverter that powers the unit will cost more than replacing the unit itself.

My Oster OM1201eovg microwave will turn on but it won't heat what I put in there. What's the problem?


Either the inverter which powers things or the Magnatron which in effect does the heating are bad.

If a fairly expensive unit it may be worth repair as these are of course two of the more expensive parts in the unit.

Mircowave runs but doesn't heat and it has a load hum.


You may need a new microwave..however, the diode may be defective or the magnatron tube may need replacing,,The magnatron tube is only warranted for 5 years so it may be used up as the model is (10years)fairly old.

Is not heating up or cooking food everything else works.


Well that's not good news! I suspect the Magnatron ( engine) is at fault here. The cost of replacement often exceeds the value of the unit. Considering these days a microwave can be bought new from about a $100.00 depending on size. Second hand ones can also be bought from about $30 with a warranty and a pre sales check.
Magnatron replacement is about $250 + labour of about 2 hrs

Microwave does not heat. several weeks ago our daughter put an aluminum can in the microwave. it has been working fine but has recently quit. could this be as a result of putting the aluminum can in the mw...


more that likley it burnt out the magnatron
(the bit that heats the food up) its a big radio stashion realy, microwaves are radio waves and bounce off things like tins but they get bounced back at the magnatron and it over heats it till it burns out, the true word is "it ages it" but at the end of the day it just dont work no more,,,to buy a magnatron is not cheap and trying to fit one yourself is likely to kill you first
as there will be 1000's of volts still kicking about inside your microwave in the capacitor witch works just like a police stun gun, however it dont just stun you it could well kill you,, not smart to tuch this bit huh? its far safer to just dump the old one and buy a nice new one,,,but keep the little one's off it this time
im told they take 20 mins per pound to cook them?
i do like children,but iv never eat a hole one yet!

Microwave ac925eqk easi tronic - been told the mag tube has gone , what is it and is it worth repairing thanks


The Magnatron is the "heart" of any microwave without it there are no microwaves.

How much depends on what country you live in and what size it was 800 1000 watts etc. But most times a new model is cheaper than a repair as there is warranty and its new and improved.

Unit about #250-350 + labour 2 hrs minimum + any travel.

If you have home insurance and your repairer can say its "Fused" yu can claim fusion on your policy. Labour is not covered neither are any other parts other than the Magnatron.

Microwave does not heat


Hello, I have been repairing microwaves for years, and it sounds like you do have a bad magnatron tube, the magnatron tube generaly runs between $65.00 and $120.00 so the answer to your question about fixing the microwave verses replaceing it, that depends on how old the microwave is, how much you paid, and if you want to put the money into for the tube, and then you also have the labor of haveing it put in if you do not know how too do it safely.. If you want to attempt to repair it and replace the mag tube, I would be more than happy to give you the instructions to do so safely!!! If you decide to fix it, send me a reply to this message, and i will furnish you with a phone number to reach me at to give you instructions...........hope this helps......p.s. I do not charge for any information i give you.....
