Can you replace microwave waveguide cover?
Replace the waveguide cover if it is burnt, chipped, or cracked. Do not operate a unit with a burnt, chipped, or cracked waveguide cover or without the waveguide cover in place. The waveguide cover can be replaced by an owner. MS24 and MW24: Pull out the old waveguide cover and push in the new waveguide cover.
How can you tell if a microwave waveguide is bad?
If there's no metal in the microwave, check the waveguide cover. That will be a small panel on the inside of the thicker side of the microwave. If it looks cracked or damaged, that's probably the cause of the sparks. You'll need to order a replacement waveguide, then unplug your microwave and replace it.
What is the paper thing in a microwave?
The cardboard (mica) covers the waveguide system that feeds microwave energy into the cavity and should not be removed. The microwave should not be used for any function if this cardboard cover is not in place.
What causes a microwave oven to arc?
The term "arcing" refers to sparks inside the microwave oven. These sparks are caused when microwaves react to gold paint on dishes, twist ties and other metallic materials, like aluminum foil.
What is a Waveguide Cover?
Waveguides lead directly to the rest of a microwave’s internal components. Left exposed, crumbs, food particles, and grease can muck up the overall operation of a microwave. A cover works to protect the waveguide itself and the rest of the microwave, so you won’t have to go searching where to donate a microwave if it breaks down.
What Does a Waveguide Cover Do?
A waveguide cover, as previously mentioned, exists to protect the waveguide and the internal mechanisms of the microwave oven from grease, dirt, and whatever else is floating around the internal cavity. If the cover becomes chipped, burned, or cracked, cease operation of the microwave immediately., as you could damage the unit.
Can You Replace a Waveguide Cover?
Yes. You can purchase a replacement cover and conduct the replacement yourself. Contact the manufacturer of your microwave for information on purchasing the correct cover for your unit. The replacement process will vary depending on the design of your microwave, but you can usually complete the task in just a few minutes or so.

What is waveguide cover in a microwave?
A microwave has a plastic or mica cover known as a waveguide cover. Sometimes, it looks like a piece of grey cardboard and is located either on one of the side walls or the top of the cavity. It is present in the hole where the microwave comes out.
How to replace microwave waveguide cover?
To replace the microwave waveguide cover, you need to follow the steps mentioned below:
Is it safe to use microwave without waveguide cover?
It is not safe to use microwave without waveguide cover as when this cover is damaged, steam and vaporized food particles will start collecting on electronic components of the microwave. When this happens, the circuit board of the microwave can short and corrode.
How to tackle if microwave waveguide cover sparking?
If the microwave waveguide cover is sparking, you should immediately switch off the appliance and unplug it. Sometimes after unplugging the microwave, the sparking will stop, and once cooled, you can use the appliance comfortably.
Microwave waveguide cover material
Microwave waveguide cover material is mica. It is present as a small cover on the right-hand side or in the roof of the microwave cavity which resembles a piece of cardboard. It is held in place by one or more screws.
How do you clean a microwave waveguide?
A waveguide cover is present on the ceiling or side of the microwave cavity. It is made up of mica and therefore, you should give special care to it.
Conclusion
A waveguide cover present in the microwave helps the microwave radiation to transmit and prevents the food and moisture from entering into the electrical components of the microwave.

What is a waveguide in microwave?
A waveguide is generally preferred in microwave communications. Waveguide is a special form of transmission line, which is a hollow metal tube. Unlike a transmission line, a waveguide has no center conductor. The tube wall provides distributed inductance.
What is the difference between a transmission line and a waveguide?
The main difference between a transmission line and a wave guide is −. A two conductor structure that can support a TEM wave is a transmission line . A one conductor structure that can support a TE wave or a TM wave but not a TEM wave is called as a waveguide.
What is the term for a hollow metallic tube that transmits electromagnetic waves?
Microwaves propagate through microwave circuits, components and devices, which act as a part of Microwave transmission lines, broadly called as Waveguides. A hollow metallic tube of uniform cross-section for transmitting electromagnetic waves by successive reflections from the inner walls of the tube is called as a Waveguide.
Does a waveguide have a return conductor?
It has wave impedance. Propagation of waves is according to "Circuit theory". Propagation of waves is according to "Field theory". It has a return conductor to earth. Return conductor is not required as the body of the waveguide acts as earth. Bandwidth is not limited.
What does a waveguide look like?
The thin sheet will look like plastic or a thin piece of cardboard.
Why do microwaves have oblong covers?
