Question about GE JVM1850 1000 Watts Microwave Oven

1 Answer

I have a GE JVM1850CH06 over the stove microwave. It works fine; however, it sometimes has a loud noise that sounds like a vibration or a bearing going out. Checked in the top part for anything loose, but didn't see anything. Inside the microwave looks like a door on the top that says open and closed, but I was not able to open it. Could that door be the noise? Any suggestions?

    I have a similar issue with a similar model... JVM1860BF001. At first I thought the noise was something caught in the vent, but since the noise only occurred when the microwave itself was on (as opposed to the vent, which I had cleaned thoroughly), I realized I had to dig further. I've since isolated the problem to the stirrer motor, it sounds like maybe something has disintegrated inside the motor housing.

    The plastic cover inside the microwave is the stirrer cover... gently remove the plastic plug and rotate the cover in the direction indicated and the cover and stirrer will drop into your hand. I ran my microwave (with a cup of water in it to absorb the energy) with the stirrer removed, and confirmed that the stirrer drive was still working... but still had the noise. I then disconnected the power to the stirrer motor (long needlenose pliers thru the vent opening, pull the plug) and voila! sweet blessed silence...

    I haven't dropped the unit to replace the motor yet... I'm assuming that's what needs to happen?

It may be a louver or the problem might be the hood vent exhaust fan.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can download GE owner's manuals and installation instructions here in order to check those by the book.

Also on those models, electrolytic capacitors sometimes fail on the control circuit board, leading to humming and chattering of relays, etc.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.

If you have trouble with your exhaust fan or cooktop lights, please have it repaired right away so the problem doesn't cascade on you.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

    A failing vent fan I can understand, but what would cause a lamp failure to lead to other problems?

Microwave buzzes when off


This is the power transformer humming, sometimes when transformers get older you get vibrations in the windings due to magnetic fields generated within the transformer which causes the humming noise, It's more annoying than anything and won't affect the operation of the microwave.

Sounds like you Magnetron has failed. The only way to repair this is to replace the part. Some microwaves have an extended warranty on this part. Check your manual and Call GE for service if it does. If the warranty has expired you might as well buy a new microwave unless you are very attached to this one. Hope this helps

When you press start the microwave starts with a low hum and sounds like a bearing or fan is vibrating, micrwave still heats up and works just runs rough. Bruce


Ther is a loose peace of metal in the magnetron, it is not a big worry, it's just noisy, i have a noisy microwave and it is working fine for 10 years now, if you use the defrosting mode you should hear the noise (on and off) because in the defrost mode the magnetron energises on and off, it could be the cabinet vibrating as well look for loose peaces of metal

Good luck!

When I read your post a shiver went down my spine... literally... You MUST be so careful working on/in Microwaves, you see they can be LETHAL...More service personnel, are killed each year servicing MW's, than any other, single piece of equipment. You see there is a BIG Capacitor inside This has enough energy, Joules, EVEN WHEN DISCONNECTED FROM THE MAINS. To KILL YOU. This must be discharged with a "Shorting Stick" BEFORE you touch anything else inside. Just touching anything connected to that Capacitor WILL SHOCK YOU. Obviously you haven't so please be careful. Anyway I have done my "Duty, and told you. What you do now, is up to you.

Grinding noise/noisy turntable


Your turntable motor is probably failing.

If you or someone you know decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

Normally you have to remove the bottom cover of the microwave (looking up from the stove top) and then the motor is accessible.
