During the modern days, microwave ovens are greatly in demand compared to conventional ovens. This could possibly be the reason that the microwave is capable of cooking food as a whole instead of going through the convection. The conventional oven applies the concept of absorbing the heat into the food’s exterior then gradually has the heat transmitting into the core. However, the microwave will pass the heat through the entire food at a tinge of time. In fact, microwaves can pass through any objects but will be converted into heat when it gets in contact with sugar, fat or liquids.
If you wish to understand how microwaves work, you would be curious to know what a magnetron is. It is a pretty huge device embedded into the microwave where it contains two large magnets being situated on the opposite edges of the anode. The anode, on the other hand, contains the cathode but surrounded by RF fields and cavities to permit the passing of electrons. During the occurrences of electricity transitory via the magnetron, the electrons will be manipulated to generate microwave radiation which will be delivered to the oven chamber.
The oven chamber is a space in the microwave ovens where the food is placed and cooked. Basically it is built of a glass plate sitting on the rotating gear that performs rotation for the food to spin during the cook for a widespread heating process. Of course, the spinning of the food will make thicker food items such as meat to have a more thorough cooking. It is often seen that oven chambers come inclusive of a light to provide users a clear view of their food during the cooking process. The waveguide is another important component of the microwave. It is a hollow metal tube that permits the transfer of microwaves travelling from the magnetron to the oven chamber. It is vital in guiding the microwaves the right channel to prevent the leaking of radiation to other unnecessary areas. Without the waveguide, it is possible that the radiation may damage the transformer or magnetron as well as harming any individual nearby.
Transformer is another important item in the microwaves, contributing profoundly to the knowledge of how do microwaves work. The large production of radiation implies the need of vast power supply and the transformer, in this case, is the responsible department of amplifying the electricity from the power supply into greater voltage. It applies the theory of how wet-tipped glasses can unintentionally result in the vibration of other glasses during the presence of a high-pitched noise.
Question by Cody: I have a dometic microwave in my RV with a bad magnetron?
So i unplugged the microwave and removed the cover and then i discharged the high voltage capacitors and removed the magnetron. The magnetron was really easy to get to for removal. I have ordered a new one and wanted to know if anyone had any tips for installation of the new one,do they just say to have a pro do it because of the high voltage? The waveguide looks fine with no spots so is it just as simple as putting the RF mesh gasket on the new magnetron (if new one does not have it) and putting in the 4 mounting screws?
Thanks and if i left anything out please let me know. And i really dont want to hear microwaves are cheap just get a new one, this one is an odd-ball size and i havent found one yet so i want to repair this one.
I know the magnetron is bad because one morning it started to make a really loud buzzing/humming noise and it would no longer heat anything, Also i tested all of the other electrical components and circuits. But i just want to make sure i put the magnetron back in right.
Answer by Rich Z
They are simple to install. I put new ones in two family microwaves. If you had enough skill to take out the old one you have more than enough to put in the new one. Have fun.
