Question about GE JVM1650 1000 Watts Microwave Oven

1 Answer

JVM1650SH05 Intermittent won't heat

I have had this unit for about 5 years. Last year the unit stopped working. Called GE they replaced the magnatron. Two days latter it stopped heating again. GE came back and replaced the magnatron again. a few weeks later same thing, stopped heating. At this point i went out and bought a counter top unit to use. One day i tried the oven and it worked. Now it works intermittently. I took it down off of the wall opened it up and all looks good inside. I checked the door switches all ok I checked for loose wires, all look ok. What else should i be looking for. I would like a solution before I hang it on the wall again.

Thank you,
Chris

On many of these GE (by Samsung) and similar models, there were "underperforming" magnetrons that would fail, often causing other damage.

In many cases, these ovens also need to have the high voltage rectifier diode and/or stirrer replaced.

In rare cases, the cavity would be overheated and the whole oven would need to be replaced.

In some cases, a service center will have a stock of magnetrons, and they may be of the "underperforming" type instead of the newest version.

So a repairman may (knowingly or not) be replacing a failed magnetron with one that is destined to fail soon.

It may be an innocent mistake, or it may be a way of not having to deal with a bunch of bad stock parts that may cost him time or money.

And if you just go put them in ovens and bill GE for the part and your customer for the labor, you're making money.

There should be a 5-9 year warranty on the magnetron.

Details of this whole magnetron saga are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.

I would check that, then call contact GE to find a different local servicer if possible.

Whether you use that servicer or a different one, I would mention or show the bulletin to them even if your model is not affected. It may have similar trouble that needs to be addressed thoroughly.

You need a thorough, competent checkout.

My 10 year old GE Spacemaker XL1400 microwave has stopped heating the microwave's contents.


probably a magnatron failure
take it to an appliance repair shop for a proper diagnosis and get a quote as repairs can be more expensive than new unit

GE Spacemaker XL - fan stopped working, light will come on and timer will count down.


either the magnatron fried , or the fuse fried... either way the microwve has to be taken down and opened up.
If you have the serial number , GE will send you a replacement magnatron (but will not service the unit for you).
contact GE and they will take care of you... the magnatrons are warranted for like 10 years....

HVM1750 won't heat


The magnatron is likely to be the problem... though I have seen the fuses go , they usually follow the magnatron.
If your unit is under 5 years old , the Mag is covered under warranty and all you need to do is contact GE at
gechsconsumerrelations@ge.com

with the serial number of your unit and they will send you the replacement magnetron imediately and free of charge.

You are responsable to have the part installed , but there are videos on Utube that will walk you thru it no problem.

Problem with the GE Spacemaker (JVM1640SJ) Microwave Oven GE Spacemaker XL1800 won't heat food anymore....It worked this morning, now won't heat. What should I do?


GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.

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.

Doesn't heat anymore. The noise from the oven is louder than it has been. Unit is 5-years old.Touch pad works fine.


5kv fuse is probably blown..this is connected to the magnatron and is probably a white casing with wires coming out of it-spade connections..fuse is inside this..prob cost about 5-6 pounds on ebay

Model J VM1650BB1 Microwave will not heat anymore. Was working fine the day before. All other items working...light, turntable and fan. What is the problem and how can I fix it?


The model is GE JVM1650BB1. After searching information on the internet, it is almost 100% the Magnatron that has stopped working. Unless I can get GE to give me the part for free and try my hand at replacing it, it does not make sense to pay to have it fixed. Whether GE or another serviceman comes to fix it, it will cost as much as a new one. For this unit, the Magnatron is over $100 from what I can tell.

If you have another suggestion, I'd like to hear it. Seems like GE and perhaps other brands have planned obsolescence with the Magnatron part. Amazing how there is no recall on this part and the consumer groups do not go after this. Good thing our airplanes don't have parts like this that can break in months or years.

Hi, I have a big over-the-range GE microwave installed in my kitchen near my prep sink, not over a range. After I had it for 2 years, I received a letter from GE that there was a problem with the...


Microwaves usually have several years' warranty on the magnetron itself - such as 5 to 9 years!

I would call the GE Answer Center with your model and serial number and ask them how many years the magnetron is covered under warranty.

Also ask them for the numbers of a few local GE-authorized warranty service centers.

(GE Answer Center® 1-800-626-2005 Open Monday 6 a.m. ET through Saturday midnight ET)

If the mag is still covered, and you take it to a GE-authorized warranty service center, you'd not have to pay for the magnetron.

And taking it to the shop will indeed save you a lot of money.

If you decide to remove it from the wall, the installation instructions will be very handy to have. If you don't have them, you can find them online here.

Good luck and be safe!
