How Do You Know if a 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 nutrient in the oven at some point in time while cooking. But accept you lot ever thought of why it happens then? What Causes a Magnetron to Fail in a Microwave?
If you know the answer and then, Yes, It'southward because of the damage caused to the Magnetron in the microwaves oven.
But, Do you know what causes the Magnetron to fail in a microwave oven? Well, there are many reasons behind it to cause a magnetron to neglect in a microwave oven. They are Magnets Cracking, Burned out terminals, Burned antenna/dome, a loose connectedness of Magnetron, Resistance continuity, etc.
Some of the causes are visually seen, and some are known merely past testing. If you are interested in farther details of the causes, and so travel with u.s.a. by swiping up the page.
What Causes the Magnetron to Fail in a Microwave
There are some causes which cook the nutrient in a microwave oven with less heat or no rut. On that account, Check for the causes which make Magnetron neglect.
And this is how a magnetron looks like.
Magnets Slap-up
This crusade happens when the damage occurs to the magnets of the Magnetron. This results in reducing the magnetic field.
And overheating of the magnets likewise causes damage to the magnets in magnetrons. The crusade 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 directly voltage. Just if any damage happens to it will lead to the insulator breakdown.
This insulator breakdown results in burning the last of the Magnetron. It increases in every cooking wheel 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 harm to information technology is reflecting off the microwaves while cooking.
These reflected microwaves crusade damage to the antenna/dome of the microwave oven past stopping it to send the microwaves.[amaplug_bestseller keyword="microwave magnetron" fashion="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 rut. This heat will burn out the other parts adjacent to the Magnetron and form black spots and fire marks on the damaged surface area.
Resistance Continuity
As the in a higher place causes are physical to observe, this resistance continuity belongs to the testing process.
This test is to bank check betwixt the terminals of the magnetrons with an ohmmeter.
Before testing, y'all need to unplug the power terminal of the microwave oven.
By attaching the ohmmeter, the continuity of the resistance should exist infinity. If the reading is other than continuity, in that location is something wrong with the Magnetron in your microwave oven.

Arc-over internally
This happens when there is a gas germination within the Magnetron. If the gas is present inside the Magnetron, information technology 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 detect when a magnetron fails.
- No heating
- Burning odor
- Arcing sounds
- Snapping sound
Deceases in heating and stops before ending
If yous discover these symptoms while cooking food in the microwave oven, immediately stop the oven by unplugging the main ability supply, and it'due south time for you lot to supercede/repair the Magnetron.
Simply what is better to supplant/repair the Magnetron in the microwave oven

Replace/Repair the Magnetron
It ever depends on the corporeality of harm that happened to the Magnetron. So, it is ameliorate to detect the problem kickoff before choosing to replace/repair it. Every bit Magnetron costs much to purchase, it's ok the trouble is repairable. If the problem is severe, and so you demand to change the Magnetron by purchasing the new i.
Sometimes the improper repair can raise the aforementioned problem once more.
If y'all want to replace the Magnetron with a new 1, make certain that a professional technician does it because a residue of the ability will remain in the Magnetron, leading to daze.
But do you know how a magnetron works? Let u.s. know the function of the Magnetron in a microwave oven.
How Does Magnetron work?
Generally, the microwave converts the electric energy into the microwave with the assist of a magnetron.
This Magnet is a vacuum tube with a cathode rod at the middle, surrounded past a hollow anode with cavities.
On the pass of electricity, the electrons heat the cathode rod. The heated cathode rod excites the electrons to the anode.
There the electric field, along with a perpendicular magnetic field, as well exists. So, the excited electrons tend to movement towards the anode in a curved way 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 Nutrient?
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 all around the cooking bedroom.
Due to the reflecting textile coating of the walls, the microwaves get reflected.
This reflection then forms a to and fro motion of microwaves and finally penetrates the food with water molecules on the turntable.
The water molecules in the food are dipolar and tend to vibrate with microwave penetrations.
The nutrient in the microwave oven thus gets heated up with the vibration of water molecules.
Conclusion:
Finally, information technology is you lot to observe out the magnetron damage symptoms and turn it off immediately. Think twice to repair the Magnetron as this will over again lead to damage within a short time after improper repair
Periodical maintenance is the all-time option to overcome all the causes of microwaves, including the damage of Magnetron.
Often Asked Questions:
Can you fix a microwave that doesn't estrus? Yes, we tin can set the problem of no heating in the microwave oven just when you have some bones knowledge virtually electric/electronic devices. No heating in a microwave oven is because of a damaged magnetron or high voltage diode.
Is it unsafe to repair a microwave? It causes danger when y'all don't accept enough noesis about the microwave. And as well, it is not a better option to repair when you are lone at dwelling house. An improper repair 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 power inside the Magnetron, which can crusade shock. And as well, the insulating material is not 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 under nonionized are less harmful to humans. But continuous exposure tin atomic number 82 to some problems like burns, blood change, etc.
