Easy Repair with Right Part
The cover is a simple replacement after you pry the old one off. Two hooks will break off. Only challenge is getting a replacement part with those hooks on. I tried another parts house and they sent me a bad part - the hooks were broken off. Someone bought it, broke it, returned it. That house did not check the integrity before returning to stock. The one I received from PartSelect was undamaged and the replacement took 1 minute.

The right part came broken in mailing package.
This was the right replacement part for my microwave oven, but the tabs that hold it in place were broken off inside the mailer during shipment. I would appreciate it if you could send me a replacement for the broken one. I tried to glue it back together, but the tabs would not stay on.

Worked but part came broken.
I pried the old Cover that a hole burnt in the middle of it. After opening the packaging I noticed the replacement cover received had a broken tab, therefore there is only one tab holding the cover in place. It's repaired with the broken cover.

I have a KitchenAid built in microwave kbms1454sss 0; which looks identical to current model kmbs104ess. Over the years the covr inlet (microwave waveguide cover) which is located in the top inside has had a hole develop in it the plastic melting away the hole is now over 1 inch in size. The microwave still work fine been using it for years.. 1) can what has caused this hole to develop 2) can this be fixed 3) what parts need to be replaced and are compatible to this model. appreciate any help you can provide this has been a great microwave and hate to spend $1200 to replace it... thanks steve
For model number KMBS104ESS00
Hello Steve, Thank you for your inquiry. Part number W11087199 would be the part that is compatible to your model. The hold can be caused by moisture or food getting into that area, or that the magnetron may be failing. You can test the magnetron with a multimeter to see if it has continuity-for safety reasons, make sure you discharge your capacitor first. Hope this helps!

Making sure this is the correct part. In the center of the interior roof of the microwave, there is a plastic part that has a hole melted open in the center. We bought the house and it came like this from the previous owner. Is this the correct part to replace that? Also, it looks like it just pops off with no screws, is this correct?
For model number KBMS1454SSS-3
Hi Jeremy,

This microwave was installed in the house we purchased. About four years ago, i replaced the waveguide cover as a hole was melted into the cover. Now, the replacement is also creating a melted hole. Is this something that i, the consumer is not doing or is doing to cause this part to melt?

Hi Jonathan, this seems like a common problem, sadly I could not find any preventative measures. Thank you for your question and good luck with your repair!

How do you remove the existing wave guide cover on my built in KitchenAid microwave?
For model number KBMS1454RSS0
Hi Joe,
Thank you for your inquiry. Replacing a microwave oven wave guide cover is a relatively simple task. That said, the process does vary from model to model. Here are the two most common ways to remove a microwave wave guide cover:
Many wave guide covers are held in place with either a single screw or several screws. Remove the screw(s), and then slip the cover out of its housing.
Other models require that you remove the entire outer cabinet of the microwave before you can remove the wave guide cover. In these models, the wave guide cover is most often secured to the internal right hand wall. With the outer cabinet removed, examine the right side of the unit. You should see where the wave guide cover secures in place. You will likely need to push down on the top of cover's clips to release it. Then reach inside the microwave and pull the cover out of the bottom slots.
Refer to your microwave owner's manual if neither of these processes apply to you. I hope this helps. Thank you and have a great day!

What would cause the glass plate to break and shatter and the plastic inlet cover to melt a hole in the middle of it while popping a bag of popcorn on the popcorn setting. I don’t want to order replacement parts until i know if i may have a safety issue and need to replace the microwave.
For model number KBMS1454RSS-0
Hi Teresa,
Thank you for your question. The glass trays for for most microwaves are made out of tempered glass. In some cases, stress points may occur in the glass as a result of extreme heat from the bag of popcorn caused by continuous cooking of it or if the popcorn is stale and does not pop. This can cause the glass to break. For some brands of popcorn, it is recommended to place the bag of popcorn on a microwaveable plate before placing it in the microwave. For more information you will need to consult the instructions on the bag of popcorn before heating it in the microwave. I hope this helps. Thank you and have a great day!
