How Do You Know if a Samsung Magnatron Is Bad in a Microwave
What Causes a Magnetron to Fail in a Microwave?
Every microwave oven has gone through the trouble of not heating the food in the oven at some bespeak in fourth dimension while cooking. Merely have you ever thought of why it happens so? What Causes a Magnetron to Fail in a Microwave?
If you know the respond then, Yes, Information technology'southward because of the damage acquired to the Magnetron in the microwaves oven.
Simply, Practice you know what causes the Magnetron to fail in a microwave oven? Well, there are many reasons backside information technology to cause a magnetron to neglect in a microwave oven. They are Magnets Dandy, Burned out terminals, Burned antenna/dome, a loose connection of Magnetron, Resistance continuity, etc.
Some of the causes are visually seen, and some are known only by testing. If you are interested in farther details of the causes, then travel with united states by swiping up the folio.
What Causes the Magnetron to Fail in a Microwave
At that place 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 brand Magnetron neglect.
And this is how a magnetron looks similar.
Magnets Cracking
This cause happens when the harm occurs to the magnets of the Magnetron. This results 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 the back to the Magnetron.
Burned out terminals
The insulator in the Magnetron helps to insulate the whole Magnetron from being attacked by the straight voltage. Just if whatsoever damage happens to it will lead to the insulator breakup.
This insulator breakdown results in burning the terminal of the Magnetron. Information technology increases in every cooking wheel and leads to severer exhaustion.
Burned Antenna/Dome
We can encounter an antenna/dome of the Magnetron in the microwave oven at the within of the filament box. The reason for causing damage to information technology is reflecting off 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" mode="Popup (Lesser)" items="5″ max="10″ location="com"]
Loose Connection of Magnetron
This is the mutual cause that happens to the Magnetron. This loose connection leads to high resistance oestrus. This heat will burn out the other parts next to the Magnetron and form black spots and burn marks on the damaged area.
Resistance Continuity
As the above causes are concrete to observe, this resistance continuity belongs to the testing process.
This test is to cheque betwixt the terminals of the magnetrons with an ohmmeter.
Earlier testing, you demand to unplug the power last of the microwave oven.
By attaching the ohmmeter, the continuity of the resistance should be infinity. If the reading is other than continuity, at that place is something wrong with the Magnetron in your microwave oven.

Arc-over internally
This happens when in that location is a gas formation inside the Magnetron. If the gas is present inside the Magnetron, information technology will requite an arc-over internally when the ability is applied of a sudden.
Symptoms to Observe When a Magnetron is Failed:
Here are some symptoms to detect when a magnetron fails.
- No heating
- Burning odour
- Arcing sounds
- Snapping sound
Deceases in heating and stops before catastrophe
If y'all observe these symptoms while cooking nutrient in the microwave oven, immediately stop the oven by unplugging the principal power supply, and it's time for you to supplant/repair the Magnetron.
But what is better to replace/repair the Magnetron in the microwave oven

Replace/Repair the Magnetron
It e'er depends on the amount of damage that happened to the Magnetron. So, information technology is better to observe the problem starting time before choosing to replace/repair it. As Magnetron costs much to purchase, it's ok the problem is repairable. If the problem is severe, and then you need to change the Magnetron past purchasing the new ane.
Sometimes the improper repair tin heighten the same problem again.
If you want to supersede the Magnetron with a new i, make certain that a professional person technician does it because a remainder of the ability volition remain in the Magnetron, leading to stupor.
But do yous know how a magnetron works? Let u.s.a. know the role of the Magnetron in a microwave oven.
How Does Magnetron work?
Generally, the microwave converts the electric energy into the microwave with the help of a magnetron.
This Magnet is a vacuum tube with a cathode rod at the eye, surrounded by a hollow anode with cavities.
On the pass of electricity, the electrons estrus the cathode rod. The heated cathode rod excites the electrons to the anode.
There the electric field, forth with a perpendicular magnetic field, also exists. So, the excited electrons tend to move towards the anode in a curved style instead of a straightway due to the magnetic field.
These curved electrons tend to resonate with the cavities of the anode.
This resonation happens at a frequency equal to the frequency of the microwaves.
Thus the microwaves are produced for the Magnetron from the antenna.
How Does 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-similar stirrer will spread the microwaves all around the cooking chamber.
Due to the reflecting material coating of the walls, the microwaves get reflected.
This reflection so forms a to and fro motion of microwaves and finally penetrates the food with h2o molecules on the turntable.
The water molecules in the food are dipolar and tend to vibrate with microwave penetrations.
The food in the microwave oven thus gets heated upwardly with the vibration of water molecules.
Conclusion:
Finally, it is you lot to discover out the magnetron damage symptoms and plow it off immediately. Recollect twice to repair the Magnetron as this volition again lead to damage within a curt time after improper repair
Journal maintenance is the best option to overcome all the causes of microwaves, including the damage of Magnetron.
Frequently Asked Questions:
Can you ready a microwave that doesn't heat? Yes, we can fix the problem of no heating in the microwave oven but when you have some basic knowledge about electrical/electronic devices. No heating in a microwave oven is considering of a damaged magnetron or high voltage diode.
Is information technology dangerous to repair a microwave? Information technology causes danger when you don't have plenty knowledge most the microwave. And likewise, it is not a improve option to repair when yous are lonely at home. An improper repair tin can lead to shock and burnout parts.
How dangerous is a magnetron? A Magnetron is not safe even the power supply of it is in an off state. There are some traces of ability inside the Magnetron, which tin cause daze. And also, the insulating cloth is non safe to touch with bare hands as it is coated with beryllium oxide, which is a danger when inhaled.
Are magnetrons radioactive? No, the Magnetron produces microwaves that come up nether nonionized are less harmful to humans. Only continuous exposure can lead to some problems similar burns, blood change, etc.
