Vibrating Noise and Electrical Smell

Used the microwave for six weeks when it began having a loud vibrating noise and electrical smell. Sent for repairs where they first said they could find nothing wrong. They then replaced the magnetron. Used three times and the noise and electrical smell has started again. Still under warranty.

The noise and smell usually come from a bad transformer. If the magnetron has burned out usually the transformer will need to be replaced as well. The transformer is right behind the grille on the right hand side.

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.

Washer is making a loud noise when its trying to rinse

you will have to open up the panel to check where the smell comes from. It could be on the motor which may cause also a loud noise or from the electrical, loose connection or bad relay may cause a noise of a different kind.

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

Vacuum is making a loud noise

Is the smell rubber or electrical. If rubber then the belt is slipping and needs to be replaced, they stretch after awhile. Also is the brush roll turning freely, or is it bound up, it may have to be replaced. If the smell is electrical, then probably the motor is going bad and will have to be replaced.
