Chances are you have a shorted high voltage rectifier diode or high voltage transformer, but it may be the magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

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.

If necessary, you can unplug the oven, temporarily disconnect the cooling fan near the microwave, and run it to see where the smoke may be coming from. Don't forget to reconnect the fan.

I have a maytag model mmv1164ws when you turn it on makes a buzzing and smells like something burning!


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

Buzzing noise and burned smell


Faulty diode pack and possibly magnetron.

Have ge profile spacesaver xl sensor. will not heat strange buzzing sound and burning smell. clock, light, vent still work


This is most likely a defective magnetron, especially with the burning smell. There are two other parts that can be a problem, the high voltage capacitor and diode, all three work together to heat food. If the magnetron is the culprit, probably cheaper to replace the microwave oven.

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.

After about 2 weeks of use, the microwave began to make a horrible buzzing noise from the "box" in the upper right hand corner on the back. It also smelled horrible. It then proceeded to stop working...


Two weeks? This is a warranty problem. The buzzing noise was probably either from high-voltage arcing or an overloaded transformer trying to drive a shorted component. The smell is from something electrical getting fried. Remember it; the next time you smell it, you'll know to pull the plug.

Faint buzzing sound smoke coming from back


The high-voltage transformer (or inverter transformer) has probably failed.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.
