SOURCE: Crackling sound in microwave vent when power is off

By "powered off" can I assume you mean that it is plugged in and at idle, not cooking, just showing the clock?

If so, I'd say your control board is failing.

If my assumption is wrong, please write back with more details.

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

Feel free to contact me directly (and please remind me of your 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.

SOURCE: burning wire smell

Hello jvtmad1,
All of the previous comments are relatively good ideas but let me offer some additional advice,
First off, You need to determine if the burning smell is coming from the Microwave itself or from the receptacle that provides power to it. Most wall receptacles are rated for 15 amps and should easily handle your microwave ovens power requirements. A simple check might be to run a hair dryer on the same receptacle without the microwave plugged into it. They draw comparable power so that should eliminate the recptacle as the culpret, On the assumption that the burnt wire smell is coming from the microwave itself, then your best bet is to return it to the store for a repair or replacement. Unless you are properly trained on how to sservice that, you probably shouldn't attempt it. As stated in previous comments, it should still be under warranty. If you have a bad filament transformer, magnetron or the wiring between them, that is not something you want to fiddle with yourself.
In summary, eliminate the receptacle on the wall as being the problem first.
If you find tha your receptacle is the problem, then you may be able to remove or disable power to it by switching off teh appropriate circuit breaker or fuse.. then take off the face plate and check the integrity of the wires going to that receptacle and making sure they are tightly secured to the terminals of the receptacle. I would assume that if that were the problem, you would notice a burnt smell as soon as you took off the face plate. Hope some of thes ideas help you resolve your problem...

SOURCE: GE JVM1660BB Microwave makes loud noise when

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

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 find helpful exploded view diagrams and order parts by entering your full model number here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)

To remove it from the wall, 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.

Microwave smell like burning rubber

Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

-Best Regards-

Smells like burnt wires

It is very possible it may have burnt wire or burnt capacitor. Remove unit, remove top cover and look inside to see if you see any burn marks or burnt wires. Also check fuse to see if it is good or not.

Burn at bottom of microwave

First try cleaning the burned mark off. Dip a scrubber in lemon juice and sprinkle salt on it; this is also great for burned coffee pots. The smell can be gotten rid of this way: Boil lemon peel in water, then put the water in a spray bottle. Not only will it make your microwave smell fresh but the lemon oil will make it easier to clean. If it still smells of burning rubber, take the back off and inspect the wiring. IF you see burned wiring, please do yourself a favor and replace the microwave!

Microwaves work by making the molecules in food get "excited"-they move more-meaning, if there IS rubber burning, then there will be minute molecules of rubber in your food, which is BAD for your immune system. If it's just burned chocolate, though, it is harmless unless you are allergic.
