Lg Microwave Model Lmvh1711st Noise

We have a LG Convection microwave that is only about 3 months old.Right out of the box it would make a very load buzzing sound while in use. This happens only part of the time, maybe 30%. The other times it makes no abnormal noise(runs quitely). It cooks just fine but this iregular buzzing noise is not right. We had a service tech. out and he replaced the Magnatron,Diode and I believe a capacitor. It was fine for about the first five uses but is now doing the same thing. Any iseas on wat the problem may be? Thanks
