What is a magnetron magnet?
Most commonly used in microwave ovens, a magnetron coverts electrical and magnetic currents into a very powerful form of heat. As the electrons move away from the filament in an attempt to latch onto positive electrodes, they are influenced by a negative magnetic field.
Can a magnetron test good but still be bad?
Sometimes, when you’re troubleshooting a microwave, it can be tricky to tell whether or not the magnetron tube is bad. In the case with many GE microwaves, the magnetron can test good according to the filament resistance specifications yet fail when you’re actually trying to get the damn thing to heat up your bagel.
What is the function of the magnetron?
Magnetrons are capable of generating extremely high frequencies and also short bursts of very high power. They are an important source of power in radar systems and in microwave ovens.
How many types of magnetron are there?
There are three main types of Magnetrons.
How do I know if my diode or magnetron is bad?
Whether it is shorted or open, a defective diode will most likely show some sign of defect. Defective diodes will usually emit an electrical burning smell, signifying its defectiveness. Also, it may have split in two, or it may exhibit a burned crack, or possibly even a blistered spot.
Where is magnetron used?
What causes a magnetron to fail in a microwave?
If the microwave is turned on when it is empty, this cause the magnetron to burn out. A burned magnetron has to be replaced as it cannot be repaired. Other probable causes behind this problem are faulty diodes, capacitor burn, defective door switch and transformer failure.
What is the function of magnetron?
A magnetron is a device that uses the interaction of a stream of electrons, guided by a magnetic field, with cavities within a block of copper to produce microwave radiation.
What is a magnetron made out of?
A magnetron consists of a short copper cylinder with a number of cavities that open into a central vacuum chamber containing a metal cathode.
