The larger part of the operations of the microwave depends on the magnetron. It ’ s the void tube that produces microwave radiation. The produced microwave radiation sickness is transmitted to the inner cavity of the microwave where food and early substances to be microwaved are placed by the waveguide. So basically, the waveguide is intentionally meant to guide and transmit microwave radiation produced by the magnetron to the cooking chamber of the microwave. Yes, the microwave can work perfectly without the waveguide cover but could be of great disadvantage to the magnetron and other internal circuits of the microwave. When the usage of the microwave without the waveguide cover continues for some time, it will render the magnetron beyond repairs.

And comparing the price of both the magnetron and that of the waveguide cover, it makes so much sense to find a refilling vitamin a soon as possible when it goes bad before using the microwave again. The price of the magnetron is more than 10 times that of a waveguide traverse .

How Important is a Microwave Waveguide Cover?

As noted earlier, the microwave waveguide blanket doesn ’ triiodothyronine add up to the operations of the microwave. Hence, without it, the microwave will be able to function to the fullest. But as it ’ mho functioning absolutely as needed, its internal components will besides be gradually been destroyed. Among the many functions, the waveguide cover plays in the microwave, two of them stand out. And these are;

  • Protect the magnetron and other electronic components
  • Guide waves from the magnetron

Protect the magnetron and other electronic components

The waveguide cover protects the magnetron and other electronic components of the microwave from splashbacks caused by cooking. So it ’ s the duty of the waveguide cover to stop any moisture or food particles that try to find their manner into the inner electronic components of the microwave. Without the waveguide covering, splash moisture and food particles will get to the home electronic components, which will end up corroding the parts. And with time, the microwave will stop working, unless repaired, which in some cases, damage may go beyond repairs. The waveguide report besides serves as protection for the passing of microwave radiation from the magnetron .

Guide waves from the magnetron

After the microwave radiation sickness has been produced by the magnetron and transited through the waveguide, the waveguide cover charge guides the radiation into the microwave. In short, it helps convey microwave radiation sickness from the magnetron to the inner pit of the microwave .

Can a Microwave Waveguide Cover Be Replaced?

The microwave’s waveguide cover doesn’t last forever. It weakens with time as splashed moisture and food particles settle on it. They can also get cracked, burnt, or chipped. And it’s always advisable to replace it if either of these gets to happen with your waveguide cover. The waveguide is normally made of the material mica. newly purchased waveguide covers are strong and tough. But reproducible spill of moisture and food particles on it causes it to weaken and becomes soft. It could besides get corroded or damaged unintentionally. You will need to make a purchase for your newfangled waveguide cover here. And for you to get the chastise parts that fit your microwave, you will have to know the microwave ’ s exemplar total. And the location of the model count varies for each microwave sword. But most frequently, the model issue of microwaves is found on the inside of the door or the talk of the inner pit of the microwave. It ’ randomness now time to remove the damaged waveguide cover. so make certain you disconnect your microwave from the mains before you start working on it. Do well to discharge the capacitor as well, as microwaves always have lethal voltage even when it has been unplugged .Can a Microwave Waveguide Cover Be Replaced start by first removing the turntable and the roller hoop. Unscrew any cheat you find on the waveguide cover that ’ s holding it to the inner cavity of the microwave. It is so easy to remove it after you ’ ve unscrewed all the screws. It might evening slide out on its own. If not, you just hold on to function and slide it out of whatever slot its edges have been put into.

immediately, you ’ ve catch rid of the old damaged waveguide screen, and you ’ re on your way to fixing a newly one. Do well to clean the edges of where the waveguide cover was if you find any dirt there. After all that has been done, you pick your newly purchased waveguide cover and slide it into where you removed the honest-to-god one from. It ’ s now time to screw the new waveguide cover to the walls of the inner separate of your microwave. You ’ re laid now. now that the microwave waveguide cover has been successfully replaced, you can now put back the microwave ’ s roller ring and turntable. And after all that, it ’ s advisable to clean the microwave. That international relations and security network ’ t character of the substitute process but will help enhance the tidiness and good smell of your microwave. Fill a jug with about 300mml of water. Squeeze half of an average-sized lemon into the water, and place your jug into the microwave. Turn on the microwave for about 5 minutes. And the clock time has been exhausted, you take out your imprison and wipe away the condensation with a clean and soft fabric. Your microwave is quick to be used to the fullest.

Can I Make My Own Waveguide Cover?

You can make your own waveguide cover if only you’ve got the means to get the necessary materials and tools in making it. So to start with your making of waveguide cover, you can get the material from any close by an appliance repair shop. You can go there with your damaged waveguide cover. And in buying the material, make sure the dimensions are at least an inch larger than your previous damaged one. Place your buy waveguide top substantial on a clean workbench or table, and place the old waveguide cover on it. Trace out the honest-to-god screen on the newly larger purchased material with a razor knife. Cut out the overlapping parts of the material per the dimensions of the erstwhile damaged one.

Can I Make My Own Waveguide Cover now that you ’ ve been able to cut out the dimension of your waveguide breed, find yourself a screwdriver. Use the screwdriver to make holes on the waveguide per the holes on the inside of the microwave where the waveguide cover will be positioned. Do well to take the necessary measurement before you cut anything out to avoid rendering the material useless or uneconomical .


The microwave waveguide cover doesn ’ deoxythymidine monophosphate have any effect on the functioning of the microwave. Hence, the microwave can be used anytime without the waveguide traverse. The essence of the waveguide cover in the microwave is to protect the magnetron from getting spilled with food particles. And it besides protects other inner electronic components from the reach of microwave radiation and splashbacks of food. These are the things that cause the internal electric components to corrode and harm the serve of the microwave .
