In microwave operations, the waveguide directs the microwave radiations from the magnetron to the interior of the microwave.

The magnetron is a device that generates microwaves, which are then used for cooking food.

It is the work of the waveguides to ensure that electromagnetic waves are directed exactly where they should be inside the microwave.

For the waveguide to perform as expected, it is covered by mica or microwave-safe plastic.

The waveguide cover is vital to keeping magnetron and other microwave parts from being ruined from splashes when cooking.

This prevents any droplets of moisture or pieces of food from entering the innermost part of the microwave.

Without the waveguide cover, splashed moisture and food particles can reach the internal electronic components, corroding them.

We now know how relevant the microwave waveguide cover is to the functioning of the microwave.

What is a Waveguide Cover Made of?

Waveguide covers are an essential part of any microwave oven. They help to prevent splashed moisture and food particles from reaching the internal electronic components.

Waveguide covers are made of either mica or plastic. Mica is a natural mineral that is heat-resistant and has excellent electrical insulation properties.

However, it is also brittle and can break if not handled carefully. Plastic is a synthetic material that is less heat-resistant but more flexible and less likely to break.

Both waveguide covers must be regularly cleaned to prevent a build-up of grease and other materials that can cause interference.

Mica waveguide covers are less expensive but more fragile, while plastic waveguide covers are more durable but more expensive.

Ultimately, your best choice depends on your budget and how often you plan to use your microwave.

But if you have children who might handle the waveguide cover improperly, then mica may be a better option because it is easier to clean when dirty.

Regardless of which type of waveguide cover you choose, always clean them periodically and keep them in good condition so they will last as long as possible.

Can You Clean a Microwave Waveguide Cover?

The waveguide cover on a microwave helps to keep food particles and other debris from entering the interior components and damaging the microwave.

Over time, the waveguide cover can become dirty and stained, making it difficult to see.

If the waveguide cover becomes too dirty, it can cause the microwave to function less efficiently. Hence, the waveguide cover needs to be cleaned.

The best way to clean it is to use a mild soap and water solution. Simply wet the cloth or sponge with the soap solution and wipe down the waveguide cover.

If the cover is very dirty, you may need to scrub it with a soft-bristled brush. Never use harsh solvents, such as ammonia-based cleaners, as they can damage the cover.

Once you have cleaned the waveguide cover, dry it off with a clean cloth or paper towel.

And always stick to the manufacturer’s instructions when cleaning your microwave waveguide cover.

Can You Tape a Waveguide Cover?

Do not use tape or another adhesive on a microwave waveguide cover. The holes in the waveguide cover allow microwaves to enter the cooking chamber and heat the food.

If the holes are covered, the microwave radiation will be trapped inside, which can cause a fire.

Also, tapes are not microwave-safe and, as a result, can melt and release harmful chemicals to your health. And can also damage the interior electrical components of the microwave.

To prevent this from happening, please do not tape the waveguide cover.

If the waveguide cover is damaged, replace it with a new one before using the microwave.


The microwave waveguide cover can be bought from a local home improvement store, online retailer, or manufacturer of the microwave.

The easiest way to buy the waveguide cover is online, but when buying, it is important to check for reviews and see if they are authorized sellers.

Manufacturers also sell their products on their websites, so you may also want to consider that.

Opting for a local home improvement store also has its advantage, as it allows you to inspect the item before purchasing it.

Depending on your preference, you can go by any outlined ways to buy your waveguide cover.
