Magnetron price

The magnetron is a high-powered vacuum tube that works as a self-excited microwave oscillator. Crossed electron and magnetic fields are used in the magnetron to produce the high-power output required in radar equipment. Today, we will review the Magnetron Price, microwave magnetron price and the magnetron sputtering system price.

Magnetron price

Replacing a microwave magnetron costs $100 to $200. This includes a part price of $50 to $100 and $50 to $100 for labor. A magnetron is the primary component that produces heat for the appliance. Now that you know the magnetron price, let us see other aspects of the magnetron.

The typical microwave magnetron tube has an average life of 2,000 hours of operation. That means you should be able to cook and heat food in a typical microwave oven for 2,000 hours before the oven loses power.

There are some causes which cook the food in a microwave oven with less heat or no heat. On that account, Check for the causes which make magnetron to fail.

And this is how a magnetron looks like.


Magnets Cracking

This cause happens when the damage occurs to the magnets of the magnetron, this result in reducing the magnetic field.

And overheating of the magnets also causes damage to the magnets in magnetrons. The cause for overheating is due to the microwaves reflecting back the back to the magnetron.

Burned out terminals

The insulator in the magnetron helps to insulate the whole magnetron from being attacked by the direct voltage. But if any damaged happens to it will lead to the insulator breakdown.

This insulator breakdown results in burning the terminal of the magnetron. It increases in every cooking cycle and leads to severer burnout.

Burned Antenna/Dome

We can see an antenna/dome of the magnetron in the microwave oven at the inside of the filament box. The reason for causing damage to it is reflecting back of the microwaves while cooking.

These reflected microwaves cause damage to the antenna/dome of the microwave oven by stopping it to send the microwaves.[amaplug_bestseller keyword=”microwave magnetron” style=”Popup (Bottom)” items=”5″ max=”10″ location=”com”]

Loose Connection of Magnetron

This is the common cause that happens to the magnetron. This loose connection leads to high resistance heat. This heat will burn out the other parts adjacent to the magnetron and results in forming black spots, burn marks on the damaged area.

Resistance Continuity

As the above causes are physical to observe, this resistance continuity belongs to the testing process.

This test is to check between the terminals of the magnetrons with an ohmmeter.

Before testing, you need to unplug the power terminal of the microwave oven.

By attaching the ohmmeter, the continuity of the resistance should be infinity. If the reading is other than continuity then there is something wrong with the magnetron in your microwave oven.

Check out the video for a test with multi-meter

Arc-over internally

This happens when there is a gas formation inside the magnetron. If the gas is present inside the magnetron it will give an arc-over internally when the power is applied suddenly.

Symptoms to Observe When a Magnetron is Failed:

Here are some symptoms to observe when a magnetron fails.

  • No heating
  • Burning smell
  • Arcing sounds
  • Snapping sound

Deceases in heating and stops before ending

If you observe these symptoms while cooking food in the microwave oven the immediately stop the oven by unplugging the main power supply and it’s time for you to replace/repair the magnetron.

But what is better to repair or replace the magnetron in the microwave oven

Replace or Repair the Magnetron

It always depends on the amount of damaged happened to the magnetron. So, it better to detects the problem first before choosing to replace/repair. As magnetron costs much to purchase, it’s ok the problem is repairable, if the problem is severe then you need to change the magnetron by purchasing the new one.

Sometimes the improper repair can raise the same problem again.

If you want to replace the magnetron with new one make sure that is done by a professional technician. Because a residue of the power will remain in the magnetron which can lead to shock.

But do you know how actually a magnetron works? Let us know the role of the magnetron in microwave oven.

How Does Magnetron work?

Generally, the microwave converts the electric energy into the microwave with the help of magnetron.

Cavity Magnetron

This magnetron is a vacuum tube with a cathode rod at center surrounded by a hollow anode rode with cavities in it.

On the pass of electricity, the electrons heat up the cathode rod. The heated cathode rod excites the electrons to the anode.

There the electric filed along with a perpendicular magnetic field also exists. So, due to the magnetic field, the excited electrons tend to move towards anode in a curved way instead of straightway.

These curved electrons tend to resonate with the cavities of the anode.

Theses resonation happens at the frequency equal to the frequency of the microwaves.

Thus the microwaves are produced for the magnetron from the antenna.

How Microwave Cooks Food?

Mainly the parts of the microwave oven are

  • Magnetron
  • Waveguide
  • Stirrer
  • Turntable

The produced microwaves will travel to the inner cooking chamber through the waveguide.

A fan-like stirrer will spread the microwaves al around the cooking chamber.

Due to the reflecting material coating of the walls, the microwaves get reflected.

This reflection then forms a to and fro motion of microwaves and finally penetrate into the food with water molecules on the turntable.

The water molecules in the food are dipolar and tend to vibrate with the microwave penetrations.

The food in the microwave oven thus gets heat up with the vibration of water molecules.

How to buy a microwave

Your Pizza Rolls deserve a good microwave. This countertop wonder, whose origins date back to the 1940s, is probably one of the most frequently used appliances in your kitchen thanks to its ability to reheat food fast (and cook a mug cake or two). There are a variety of options when it’s time to select a microwave, so we’ve broken down the options you have when you’re ready for a new microwave.


The first decision you need to make about a new microwave is where in your kitchen you want to put it. The location affects the price, features, size and installation of the appliance. You have three main options:

This is the most common type of microwave. They generally cost less and are significantly easier to install than other models. Just find a spot on the counter for it to sit, plug it into an outlet and you can use it right away.

The biggest issue with the countertop microwave is how much space it needs. If you have limited room on your countertop, you may either want to look at the smaller countertop models available, look into placing your microwave on a small cart, or consider another style of microwave.

Price: $40 to $700

External dimensions: From roughly 10 by 18 by 14 inches for compact models to roughly 14 by 24 by 20 inches for larger models

Internal capacity: Less than 1 cubic foot to more than 2 cubic feet

Wattage: Typically 600 to 1,200 watts

You install this style of microwave above your range, which will save you some counter space. These models have vent systems that take the place of the oven hood and lights to illuminate your cooktop.

Price: $190 to $1,300

External dimensions: Usually wider than countertop models, about 16 by 30 by 15 inches

Internal capacity: Less than 1 cubic foot to more than 2 cubic feet

Wattage: Typically 600 to 1,200 watts



Built-in models that you place among custom cabinets or paired with built-in, full-sized wall ovens are the most high-end (aka expensive) types of microwaves. Some microwaves in this category are even designed specifically as drawers with a compartment you pull out for your food.

Price: $500 to $5,000 and up

External dimensions: This varies widely depending on type, and drawers tend to have more depth than countertop or over-the-range models, hitting about 15 by 30 by 26 inches

Internal capacity: Less than 1 cubic foot to more than 2 cubic feet

Wattage: Typically 600 to 1,200 watts


It’s important to find the right-sized microwave that will meet your food needs and fit in the space you have for it. First, you want to measure the counter or other space where you plan to put your microwave. Then, measure the height, width and depth of any model you’re considering to find out if it will fit on your counter top, over your range or in a custom spot. The external dimensions can vary a lot, from 10 by 18 by 14 inches on the smaller side to 14 by 24 by 20 inches on the larger side.

Then there’s also the internal capacity, which can range from less than 1 cubic foot to 2 cubic feet or more. There doesn’t seem to be any set rule for how internal capacity correlates to size (like 1 cubic foot = small, 1.5 cubic feet = medium, etc.), but here’s an attempt to break it down:

Compact: Under 1 cubic foot

Midsize: 1 to 1.5 cubic feet

Full-size: 1.6 to 2 cubic feet

Extra-large: More than 2 cubic feet

Most microwaves are somewhere around 1.4 to 1.8 cubic feet. Still not sure which size you need? If you’re out shopping, bring in a plate or bowl from home that you plan to use often to make sure that it fits inside the microwave.

Still in doubt? Measure everything, take notes and check with your appliance retailer for help deciding what would work best. For over-the-range and other built-in models, you most likely won’t be the one installing your new microwave, so you can always avail yourself of their expertise.


Microwave wattage equals power. In general, the higher the wattage, the faster and more evenly your food will cook. Most microwaves sit somewhere between 600 to 1,200 watts. Larger, more expensive microwaves tend to have a higher wattage, so this is a price and size consideration that can strongly influence microwave cooking performance.

Many microwaves share common functions. Here are some microwave cooking essentials: cook time, defrost, power level and timer. Each one requires your direct input, but they are usually very easy to set. Most microwaves have touch panel controls and a rotating carousel to spin your food for more even cooking.

Default settings

Many microwaves come with preset cooking modes so you only have to press one button to automatically cook a dish. For example, many microwaves have a “popcorn” button that will cook your bag based on factory settings. This can be handy for common dishes you heat in the microwave, but you’ll have to figure out if the microwave’s default cook times work for your own food. Other common presets include: baked potato, pizza, beverage, frozen dinner and reheat.


Manufacturers are increasingly including features in microwaves that mimic what we see in full-size ovens, such as a broiler. This is a good addition for finishing off a dish or cooking something for which you’d prefer more direct heat.


A convection fan that’s built into the back of a microwave oven circulates the heat around the food to cook things more quickly and evenly. (Many new full-size ovens come with at least one convection fan.) However, microwaves with convection fans are generally more expensive than those without.

Inverter technology

Inverter heating is another option available on some high-end models. If you want to heat something at a 50 percent power level, most microwaves actually switch between 100 percent power and 0 percent power to average in at 50 percent power. This doesn’t yield great results if you want to heat something on a lower heat and achieve an even result. So, some models now use inverter technology, which maintains a consistent 50 percent power. That way, you can poach salmon, make a fluffy omelet, etc.

Other advanced features

In addition to new heating technologies, higher-end models usually have more presets than just the basic pizza, popcorn and baked potato standard. Some use moisture sensors to detect food doneness. And we’ve started to see models include LED lighting on the interior.

“Smart” technology, i.e. options that connect microwaves to the internet and other products, aren’t as widespread in microwaves as we’ve seen in other kitchen appliances. However, we’ve seen GE Appliances include Bluetooth technology in some of its over-the-range microwaves. This connection, which GE calls “Chef Connect,” pairs the microwave with compatible GE ranges so the light and fan beneath the microwave automatically turns on when you turn on a burner.

More options

Will the June Intelligent Oven become the next microwave?Tyler Lizenby/CNET

Other small appliances have started to make a case for forgoing the microwave, such as steam ovens that use water to cook for more moist heating or the basic toaster oven that mimics a full-size stove. These options promise to cook more effectively than a microwave, but it might take longer to reheat your food.

Smart countertop ovens have also started to become an option. The June Intelligent Oven uses facial recognition technology to identify food and cook it automatically, and the Tovala Smart Oven will scan packaged meals for automatic cooking, including frozen meals from Trader Joe’s. These options are promising, but the technology is too new to determine whether or not these will become kitchen staples.


Finally, it is you to find out the symptoms of the magnetron damage and to turn it off immediately. Think twice to repair the magnetron as this will again lead to damage within a short time after improper repair
