If your microwave is making an unusual or loud humming noise, you may have a problem with the magnetron. This component is part of the high voltage circuit and provides the microwaves that generate the heat. If the magnetron is defective, it may cause a loud humming or buzzing noise.

Beside this, how much does it cost to replace a magnetron in a microwave?

Here are prices for parts (excluding labor) that commonly need to be replaced in malfunctioning microwave ovens: Magnetron: $100–$150. Transformer: $100–$150. Touchpad: $20–$50.

One may also ask, why does my Samsung microwave buzz? Samsung Microwave is loud or noisy. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances, the magnetron emits a low hum. A defective high-voltage diode can also cause the magnetron to be loud.

Beside this, what sound does a microwave make?

The whooshing sound a microwave oven makes has nothing to do with the magnetron, which resonates at a frequency far too high for human hearing. The noise is from the fan that blows air across the magnetron to keep it cool. HUM: Microwave ovens also produce a hum.

Can my microwave explode?

As others have mentioned, microwaves themselves don't explode, they heat things. Since they can penetrate food, they heat water in the food that's on the food's interior.
