GE microwave replacement magnetron

I ordered a new magnetron from GE, part no. WB27X10370, for a GE JVM1850 microwave oven. They sent a replacement, part no. WB27X10017, as they do not make the original magnetron any longer. The old magnetron had 2 electric plug recepticles. The new one has one. Could you please tell me what is to be done with the 2 wires that went to the top plug that does not exsist on the new magnetron?

    Yes, it is the thermostat. I thought the new magnetron would come with a new thermostat attached to it. Removing the old thermostat and attaching it to the new magnetron did the trick. The microwave works great now. And GE sent the new magnetron free of charge even though the microwave was 3 years old. Thanks for your help.

    MicrowaveSvc,



    I had read on another web site that GE was having an abnormal number of magnetron failures on their Spacemaker microwave ovens and that I should call and see if ours was part of a recall. I told GE that the magnetron was bad and that I wanted a new one for a local repairman to install. They just asked for the model and serial numbers, name and address and sent it out. After it arrived I called three appliance repair shops and they all said they would not install it. So I installed it myself. GE did not ask me to sign anything. And yes, the part that I transferred to the new magnetron is listed as a "TCO - MAGNETRON", part number 62 in their parts diagram, which I assume is the thermal cutout you spoke of in your solution. Thanks again. You really know your stuff. Works like a charm.

    I have an old (18 years) combination oven with microwave on top from GE. The microwave is heating sporatically - meaning it might heat something now and then it won't immediately after and then it will heat up something later - so it isn't dead but it won't heat constantly. Is this the magnetron tube or a thermostat or something else? I don't really want to hire a technician because it would be worth more than the microwave - is this something i could fix myself (i'm pretty handy) or is it just dead. Thanks.

    The manetron on my GE space saver JVM1860BD has gone out. I have called GE they won't send me one. They want to send a tech. How do I get around this so I dont't have a major expense?

    Flyholm,



    Does the top plug has two black wires ? My old magnetron also has 2 plugs while the new replacement one only has the bottom plug (white). Are you saying that the top plug can be removed from the old magnetron and attached to the new magnetron ?



    Thanks

    2001 spacemaker microwave, lights up, sounds like it is working - a bit louder, but has no heat.

    WOW!! Can you reply back with a photo of the original magnetron?

    The new WB27X10017 can be found on Google images.

    Magnetrons have two terminals:

    The F terminal connects only to one of the two filament leads of the high voltage transformer.

    The FA terminal connects to the other filament lead of the high voltage transformer AND to one terminal each of the high voltage diode and capacitor.

    The case is actually the third terminal for ground.

    So I'd be very interested in seeing that photo of the new mag!

    Otherwise, maybe you're thinking of a thermal cutout or thermostat which must be moved from the old magnetron to the new one?

I also have a HotPoint (GE) Spacesaver Microwave Oven (MWO)that we got at Home Depot about 3 yrs ago. The magnetron quit yesterday and I found out online that this is a common occurance with GE MWO's. I found this string and thought I would attempt to have GE send me a magnetron to replace the defective original part.

I called Customer Relations (1 800-386-1215) and spoke with Nikita. I informed her nicely that I was aware that this is a common problem with GE MWO's and that I am a Union Electrician who would like to perform this repair myself. I simply needed the replacement part. She was very understanding and asked for the model and serial number and after a few minutes she supplied me with an order confirm #.

The part should arrive in a few days via FedEx and we will be back into space age cooking and also our appliances will still match. Thanks to all who posted to this string and clued me in (You have saved me a C note!).

I also wanted to send my appreciation to everyone in this thread and David in Omaha for the specifics he wrote. I was able to secure a replacement magnetron free-of-charge from GE this morning. I called the Customer Relations number; at first Mrs. Neighbor in CR asked if I wanted to purchase a replacement part, I also nicely explained I was aware this was a common problem and was requesting a free replacement, they verified my warranty status, transferred me to the warranty department where Angela also verified my warranty then took my address, provided me a order # and said it should arrive in 5 - 7 days.

Thanks FixYa!

At first I was concerned but then I realized what it was.

Congrats on their sending you the mag!

How did you convince them to do that? Did they make you sign a waiver?

We're happy to help and we appreciate your thoughtful rating of our answer.

    Thanks VERY much for giving me the details of how you got them to send the mag to you.

    I'll certainly share that with other owners so they can benefit the way you did.

    And of course I'll continue to ensure that folks have access to the necessary safety and installation information to do the job correctly and safely.

    And thanks for your kind words.

    You got it done safely and at no charge and made GE do what they should have done to stand behind their product.

    If I could rate you, I would give the rank of HERO.

    Good cooking to you!

I just talked to customer service and the part is under a 10 year warranty, but the catch is that a GE Authorized tech must come out and identify the problem, and if it is the magnetron, they can order the part for at no charge, but I would be responsible for the service call and installation. She said this is the rule on getting a part under warranty. The part is available on line through GE for $155 plus shipping, so I now have to call around and find out how much a tech will cost.

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

It just makes a growling sound and does not heat any thing up. The panels are working.lights timer ect..


The problem is most likely the magnetron that has failed, the two other possibilities are the high voltage capacitor and diode, all three work together to produce the heating a affect, repairs can be as much as a new microwave oven.

Rest all works,but not heating micowave xl1800


When the microwave does not heat the food, it means that the magnetron circuit has failed. It the part that generates the microwaves that heat the food. Often the part fails by shorting out causing a loud buzzing sound when you try to microwave something. The replacement part usually costs almost as much as a new oven, so it rarely cost effective to replace. Sorry.

Microwave all works,but does not heat.


Seames your magnetron is dead (device that produces the microwaves) or could be a fuse (be cearful when opening electric appliances), if it's the magnetron i'm sorry to tell you it's almost as expensive as a new microwave...

Good luck!

My GE Profile over range microwave spacemaker xl 1800 model jvm1870bf02 was working just perfect until my daughter decided to use the microwave as a timer and actual ran the microwave with nothing inside...


Magnetron is blown.
This high-energy microwave-transmitting device hides behind a small plate on side of oven.
The waveguide sticky-out part looks like a small tube.
Normally, water molecules absorb the energy, heating the food.
Without an absorbing 'load' inside the oven cavity, the high-frequency, high power energy bounces back into the magnetron and it destroys itself. (Magnetron Hari-Kiri).
In a nutshell, tech must renew magnetron.

Can I just disconnect the motor and operate the oven without it


You must have the fan running to cool the magnetron tube. It would burn up in short order without the fan.

Please Help my GE Microwave produces no heat!!


Most of the time it seems to be the magnetron. The Magnetron is what heats the food, when you remove the magnetron sometimes you will see signs of wear like a black or brown spot on the tube sometimes there is even a hole burned through. A cheap place to find these part is Global Micro Parts in Dallas TX. Usually Magnetrons are about $30 - $45 and shipping is only 7.95 there web site is www.allapplianceparts.com
