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 completely.

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.

THe buzzing noise is most likely coming from the magneton. The magnetron is the main component of the unit (it generates the microwaves). Replaceing it can be very expensive. You may be better off getting a new oven. Prices for new microwave ovens have dropped significantly.

Why is there a humming noise coming from the right, front bottom corner of my microwave when not in use?


That is because the power transforme is located in that area and being a transformer uses iron laminations to transform the energy from the primary winding to the secondary winding/s using magnetism caused by the alternating currents. This in turn produces eddy currents that excite the iron and cause vibration to be set up, (the principle is similar in a loudspeaker). That is where the noise is coming from.
Tightening up the laminations may help but it is normal for a small amount of humming/buzzing noise dependent on the manufacturing process of the transformer.
I hope that explains it for you.

You can check the relay and related driving circuit. If there is a short in the relay driving circuit there is chance for this type of problem. or the micro processor may be defective.
