Complete Buying Guide: How To Choose The Best Microwave Waveguide Cover

microwave waveguide cover

Most of the microwave-users are not aware of the waveguide covers in the oven until their microwave conducts some “chemistry experiments” inside. When they receive a box of a new ovens, they often mistake the backup waveguide cover with cardboard and throw it away. And when the terrifying fireworks are on display, they often end up saying goodbye to the young beloved oven, not knowing that the right solution was thrown out at the beginning.

Or, in a little more positive case, the householders have to replace the expensive magnetron or spend nearly hundred buck of dollars for a call of service. However, those solutions are unreasonably costly. Luckily, a new appropriate waveguide cover will renew your oven at a price that you cannot bargain anymore.

Thus, choosing a new waveguide cover for your oven is a considerably worthy affair. And knowing how to choose the right cover for the microwave is essential as well. Here are some key factors that you should elevate when it comes to the replacement of the old waveguide cover:

microwave waveguide cover

Size

There are thousands of microwave models from a wide range of manufacturers. The dimensions of the ovens are different, so the size of the microwave waveguide covers are not the same for all of them. You should make sure to have the original cover’s exact numbers about dimensions. This is very important because it would save you both time and money.

Ignoring the step to identify the size of the right cover can lead to wasting. If the slice is too large, you can still make some adjustments with a craft knife or a pair of scissors. That is still better than the case that the newly-purchased cover is too small for your oven. If the cover is tiny to fit in the tabs, the magnetron is not fully insulated and the flashes may not go away. You will face trouble again right after the installation and have to order another pack of waveguide cover.

On the contrary, if you detect the right size for your cover, the installation will be much easier. It may be a perfect match for the tabs. In either case, it does not take you much time and effort, compared to the consequence of not having the right size.

The good news is that you do not have to take out the rulers and make the exact-to-millimeter measurements. For your convenience, the stores have already adopted a new method that simplifies the task of size determination for the oven-owners. You just have to remember the brand of the manufacturer and the name of your microwave model. Type it out and poof! The results are just what you need. But I still recommend checking the original cover and grabbing the size for your microwave waveguide cover. Better safe than sorry, right?

Shape

After having the detailed dimensions for a new suitable waveguide cover, jump to the next step: Choose the right shape. This is as important as the stage of identifying the size of the cover that I mentioned above.

If you do well at this step, I can say that it will smoothen your process of inserting the cover. It might take you just a few seconds to put the cover in, given that you have the right size and shape.

Some models are designed with slots to insert the cover. Some others have tabs to keep the slice. Some microwaves hold the pad with plastic rivets.

Due to such a variety of designs, shapes for each microwave may not be the same. After studying the waveguide covers, I found that these are the 3 most common shapes for all microwave models:

microwave waveguide cover

In case you feel like doing some DIY stuff and creating your own waveguide cover with mica sheets, these shapes may not be a big problem. It is quite easy and simple to trace and cut out with a box cutter of a pair of scissors. But be careful with the holes. The cover may break if you apply too much pressure.

Ease Of Installation

The oven-owners can be divided into 2 groups. The first one concludes that the installation of the waveguide cover is so easy that an unskilled innocent 4-year-old or even a  77-year-old can do it.

They told their stories in jubilance, saying it took just a few seconds to fit in. And the second one finds the task quite challenging. They like the insertion like it was an impossible mission. Most of them had a couple of times breaking the covers and only succeeded at the nth time of trying later.

Although most of the covers are made of mica paper and silicone resin, the extent of complexity during the installation somehow is not the same.

I found some products suffering from complaints about the fragileness of the cover, describing how it easily snaps with just a bend or a drop. Yet there are products that receive no negative comments about the installation. There are even compliments for its flexibility, showing that it fits well.

If you are a handyman, congrats, you are able to pass this test of skillfulness. If you are not, don’t worry at all. The recommended waveguide covers that I mentioned above may help you avoid the risk of broken covers. But you still should keep in mind that it is very important to take your time. Be patient and you will make it.

Thickness

I suggest that this is an optional factor, but it is still helpful. Let’s have a quick review of how the waveguide covers work. The covers are not big, but they have a big function.

The mica paper protects the magnetron from heat, greases, and food particles, by resisting heat and bearing the spinouts. Sooner or later, when the old cover has sucked enough in moisture and oil, the magnetron exposes the spinouts and causes the dangerous arcing.

There are stereotypes that insist on most of the buyers’ minds. One of them is, the thinner the cover, the more flexible it is so it will make it easier to install; and vice versa, the thicker the cover, the more brittle it is.

Actually, I discovered that the thicker ones are sturdy enough not to crack and have a larger capacity for greases, while the thinner ones turn out to be more brittle and they do not stay long.

As the thickness also contributes to the ease of installation, I don’t recommend you to buy too thick covers that make your installation more difficult. Choose the moderate thickness that is suitable for insertion. An appropriate thickness means a reasonable service life for the waveguide cover.

Tips:

You should have a couple of backups in case of over-cutting or breaking. Be careful with the sharp corners, you can have it ground for safety. During adjustments, it’s better to use a box cutter or a craft knife than a pair of scissors.

Cutting and trimming may create some dust. You had better do that on a spreading sheet of old newspaper to avoid it dropping on the floor.
