Microwave Parts, Names, Functions, Diagram

In most homes, the microwave is one of the important instruments used to cook food and defrost, grill, or reheat. Whenever someone wants to make food hot, they can place it in and heat it. In the winter season, the use of microwaves is more. Due to its frequent use, there are chances of a breakdown. If you know the microwave parts then you can find the problem and replace them. But if you are not aware of the parts of the microwave then the repair person needs to call. There are possibilities to take a more repair cost or suggest to replace them. So to avoid such possibilities, we must know every part of microwave and its functions.

Parts of a Microwave and their functions

Transformer

As we know, microwaves require high voltage energy to cook food instantly. In the United States, an electrical plug gives electricity of voltage of 115 Volt-only, and this is not sufficient energy to cook the food instantly. So the microwave has a high voltage transformer in the microwave.

This high voltage transformer alters the voltage at the desired level to cook the food instantly. A high voltage transformer consists of a series of capacitors, and it loops the electric current to multiply the power and gives it to the microwave.

Magnetron

The microwave magnetron consists of a vacuum-like tube and a strong magnet placed on the same side of the control panel. Its function is to receive high voltage electricity coming from the transformer and convert this electricity into the microwave. It is for cooking the food.

Magnetron uses a specially created diode that controls the electron using a magnetic field. These two round-shaped magnets deflect the electron and move in a circular direction. This electron moves in the cavities of the anode and creates microwaves.

Earlier, this magnetron is big, but due to technological evolution, magnetron comes in a compact size which is very reliable.

Waveguides

A waveguide is to guide the microwaves coming from the magnetron. It is made from a hollow metal tube that transfers the microwave into the microwave cavity.

The inner wall of microwaves is reflective, which helps to heat the food quickly.

Cooling Fan or Stirrer

As we all know, heating instruments have a chance of overheating, and the same thing applies to microwaves. A cooling fan inside the microwave cavity helps to reduce overheating.

It overcomes the extra heat within the cavity and brings it back to the safe level by distributing air in the cavity.

In older microwaves, the stirrer is used instead of a cooling fan, but its function is the same as a cooling fan.

Cooking Case or Cooking Cavity

It is helpful to cook, grill, or defrost the food inside the cooking case. As we all know, the size of the cooking case is smaller than the entire microwave.

The microwaves coming from magnetron are very harmful to every human being. So that the cooking case is deep & walls are very thick just because not transferred microwaves through the atmospheres.

Rotating Disc / Turntable

A rotating disc or turntable fits inside the microwave through a locking mechanism. Its function is to rotate the food in 360 degrees which will help to cook the food more evenly from all directions.

It is made up of a glass plate. This rotating disc is easy to remove, and we can clean it also.

The door of microwaves comes with a special seal at the sides, which will help to close the cooking cavity in a very secure and protective manner.

Control Panel

The Control panel is a set of buttons or knobs to instruct the food by performing proper settings. The Control panel comes with knobs, buttons, or touch screens depending upon the type and brand of microwave.

With this control panel, we can set cooking time, the intensity of cooking, or some function such as defrost or grill mode. The series of numbers starting from 0-9 helps set the cooking timing & one digital display that counts the remaining time of cooking food. We can also set the alarm for the cooking time.

Door

It allows the user to place or removes the food from the microwave. Its function is to seal the microwave from all sides. It has a rubber seal on the edges of the door, which secure the compartment when the door is closed.

This door is also preventing the microwave from getting out from the microwaves. The microwave door comes with transparent glass, which helps to keep an eye on the food inside it.

Metal mesh lining on the door prevents the microwaves pass through the glass door. The gap in the mesh is large enough to keep eye on the food inside the cavity.

Power Cord

The power cord is the cable to give a direct supply of electricity to the microwave, and it directly connects to the main power supply.
