My microwave is sparking at the top of the interior ceiling. The sparks originate from a small metal looking panel rectangular in shape about 2”x3”. What is the name of this part and what is its function? Is it a necessary part for the operation of the microwave?
For model number KMHC319KPS0
Hello Joshua, thank you for contacting us. It seems like the part you are describing might be the waveguide cover. The waveguide cover is a small panel inside the microwave that protects the waveguide, which directs the microwaves into the cooking cavity. It is typically made of a material that can withstand high temperatures and is designed to prevent food particles and moisture from entering the waveguide, which could cause damage or sparking.
Yes, the waveguide cover is a necessary part for the safe and efficient operation of the microwave. If it is damaged or dirty, it can cause sparking, which is a safety hazard. It is important to keep the waveguide cover clean. If the wave guide cover is clean and still causing the sparking, then you may need to replace the wave guide cover, part number PS16875961, to solve the problem. Glad to be of assistance!

Unless you have a very comfortable background with electronics and electricity, I don't necessarily recommend taking apart a microwave. If you are very handy and are going to be VERY cautious to follow the rules of discharging caps and testing voltages before moving forward, then go for it. That said, I took the microwave off and apart.
... Read more Not knowing where to find the parts, I was fortunate that the installer put the instruction book for the microwave inside the front vent slot above the touchpad for reference. it details the location of every part and it tells you very clearly what each part you test should show specific to this microwave on your multimeter. Find this guide online if you don't have it. Turn on the microwave for 20 seconds with a glass of water to make sure it's not heating - that with the noise means it's eeither the magnetron, cap, or diode. Read the notes on this site for all of the basic things to look for with the magnetron, diode, and capacitor. Once comfortable with the guide, locations of those devices, and how to test, then take it down and apart. Unfortunately, I didn't do all those things in that order, and it only wasted a lot of time trying to find the parts. Once I found the parts and put all the screws and covers back for all the areas that didn't need to be accessed for the repair, testing went quickly. The diode was bad. Ordered a new one and had it in 3 days or so. That means your microwave will be apart and sitting somewhere for a little while until you get the part and have time to repair it. Putting the diode back isn't too bad. Reassemble the microwave and put it back up again. If i had to do it again, it would take me 20 to 30 minutes once the microwave was down and on a table. Also, I used some bricks with towels over them or you could use some sawhorses to keep the microwave elevated so you can plug it in and run it after installing the new component. Again, make sure you discharge the cap before touching anything again even if you didn't run it, but just plugged it in.
