SOURCE: burning odor, no heat

A burning smell along with a different sound (growl) USUALLY indicates a breakdown in the High Voltage Side. This is not a direct short (short circuit) or the line fuse would have blown shutting everything down. The High Voltage Side is made up of-- The Secondary ,or High Voltage Side of The High Voltage Transformer, A High Voltage Diode, A High Voltage Capacitor, and The Magnetron. If The High Voltage Transformer is the problem it will smell like a florescent light ballast burning, and will smell each time you turn on the MW. A HV Diode burns and opens, thus no more smell. A HV Capacitor usually does not burn nor does the Magnetron. There is no Cheap-Fix unless you can see that the HV Diode is burned into and you can get to it to replace. CAUTION: Always unplug from power before attempting to repair. NOTE: If you replace a Diode make sure it goes back in the same direction it came out. Yes there is a front and back.

SOURCE: Microwave makes loud noise and does not heat. Smell of light burning

After the way GE behaved by doing business with Iran, wouldn't buy a thing from them. look for the equivalent product from another source. Jeffrey Immelt's citizenship should be revoked and he should be sent off to live on a deserted island

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

SOURCE: I have a JVM1630WB GE Spacemaker microvwave oven.

It's almost certainly a shorted high voltage rectifier diode or a failed magnetron.

We have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Here are some handy links you or someone you know can use for test help:

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html

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.

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.

You can also find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If it's within the magnetron portion of the warranty (for this model it's 10 years from the date on the tag inside the unit) but out of the original full warranty (1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

G.E. they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.


If it is not within the magnetron warranty, you can find helpful exploded view diagrams and order parts by entering your full model number here.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

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

Something is burning, there are high voltage parts in a microwave oven and they wear out. You probably need a new diode. Part number WPW10492276 google it

Coleman EB15A - Buzzing noise from transformer area, no heat or fan


see this causes and proceed. God bless you
Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Exhaust Fan Motor If the microwave is loud when running the fan motor might be
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

LOUD BUZZING NOISE AND THE ANSWER I RECEIVED WAS FOR A DIFFERENT MODEL. CAN I FIX IT MYSELF?


If the loud buzzing noise is present when cooking food, the magnetron is the likely cause, some models are louder than others. But if the buzzing noise is there without the microwave running it should be checked. No! this something that should be checked by a professional for safety.

Buzzing sound when you turn on .also smells like burning


The magnetron is failing, "heats food" and in some cases gives off a burning smell, "classic symptom" repairs will run close to a new microwave oven or more.

Microwave makes a loud buzzing noise and emits a burning plastic smell


This indicates the magnetron has failed, buzzing sound and odor are classic symptoms. It is cheaper to replace than have it repaired.

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

My Kenmore 721.626222 which I have had about 6 years, runs but does not heat. There is also a strange smell - something like a burning smell.


When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

Whirlpool microwave makes loud buzzing noise


When your microwave oven won't cook your food, and, you hear a loud buzzing sound, it’s normally caused by a faulty (a) diode (b) high-voltage capacitor (b) magnetron.
The diode would be the most likely culprit of the three components. It’s also by far the cheapest!

Kenmore 721.80524500 makes a buzzing, grinding noise


Your problem is due to the "magnetron" arcing to the wave guide within the microwave. Picture someone arc-welding stuff together inside the microwave casing, that's essentially what's happening. It is a fire hazard and you should stop using the microwave immediately. As far as I know, there isn't a recall on that particular model (though there was on another similar Kenmore/Whirlpool model) so if it's out of warranty, you're out of luck.
