Part fit perfectly. Repair was challenging.
The part was a perfect replacement the challenge was the step by step process of removing the sheet metal covers and remembering where all the screws went. I would suggest taking before and after pictures of all the sheet metal and it screws placements also the wiring harnesses. Definitely need two people to remove wall oven from cabinet and also definitely discharge capacitor. It took about 3 hours but microwave is working fine now

Microwave worked perfectly but would no longer heat.
Looked up symptoms on parts select website. Ordered mag and diode. Very easy to take micro off the wall. Easily removed screws holding the skin on. Found diode. Really didn't need to replace it but since I had a new one (fairly cheap), just did so. Diode only installs one way. Can't botch it HOWEVER, MAKE SURE THE ONLY PART OF THE D
... Read moreIODE TO TOUCH THE GROUNDING POLE IS THE SCREW DOWN LEAD. IF THE OPPOSITE END LEAD, THAT WHICH IS THE PUSH ON TERMINAL, TOUCHES THE GROUNDING POLE, YOU'LL GET ARCHY SPARKY. The magnetron goes in very easy. Simply pay attention to how you removed it and reverse that process installing the new one. There are easy to use YouTube videos that show magnetron replacement. You can do this easily and save your microwave and $$ while doing so.
PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components,

You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

My microwave began suddenly making a loud humming noise while cooking food.
My microwave began suddenly making a loud harsh humming noise while cooking food. I did not let it go on long enough to know if it cooked the food or not. I did some Internet research and learned that it was likely the Magnetron. The test for this was to run the microwave for at least a minute on the lowest power setting and see if the no
... Read moreise cycled on and off. It did, so I (actually, my wife) ordered the part from partselect.com using the model number. I was successful in replacing the part, and we are back to microwave popcorn and quick defrost for a price that was less than a service call, however, it was time consuming, required a large work area, and access to 5 out of 6 sides of the unit. So proceed at your own discretion
Caution:
The first thing in every set of repair instructions was to discharge (short-circuit) the capacitor, as it may store large (as in lethal) amounts of electricity even when it is not connected to a power source. I had never done this, but found these instructions:
“Discharging your microwave's capacitor is absolutely essential in preventing injury to your microwave, your tools, and yourself. A capacitor stores a large amount of electricity even when your microwave is unplugged, and it must be discharged before beginning any repair. A capacitor is discharged by creating a short circuit between each of the two capacitor terminals, and between each terminal and the chassis. The chassis is the metal mounting (bare metal surface) of the capacitor. Read these directions thoroughly before you proceed. With your microwave unit unplugged, touch the blade of a well insulated screwdriver to one terminal. Gently slide the screwdriver forward until it reaches the other terminal, holding it there for a few seconds. Be aware that this often results in a loud and startling 'POP'. Repeat this procedure in order to create a short circuit between each capacitor terminal and the chassis (bare metal mounting plate surface). This same method can be applied to a capacitor having three, and not two, terminals.” I had not run my microwave in over a week, and then while my part was shipping, left my microwave 'unplugged' for more than two days, and my capacitor apparently discharged itself, although I did go through the above procedure carefully and completely - just in case. Step-By-Step: 1. You must remove your microwave from the cabinets - it is impossible to repair otherwise. This is best accomplished with 2 strong people - my wife and I made it work, but wished for another guy. a. While supporting the microwave, remove the two screws coming down through the cabinet above. b. Lift the rear of the microwave as much as possible, then tilt the front down - there is a clip high on the left side, as well as the hinge/clips on the bottom. c. If you do not lift it off the wall all at once, you may have to lift the rear even farther to remove it from the hinge/clips on the bottom. Important Note: Always beware of the microwave door, if it is bent or broken and cannot retain a seal, the microwave not function as a safety feature to keep from releasing microwaves. 2. Remove the vent cover on the top/front of the microwave - be careful, it's plastic. 3. Remove the vent cover and light panel on the bottom of the microwave - this is several screws and some simple wire clips. 4. Remove the "shell" (top and sides) of the microwave - this is several more screws on the back. Make sure to remove the plate that is holding the cord in place on the top. 5. Remove the interface panel by the screws on the top (which had been hidden by the vent cover) - the wires can remain attached, just slide it aside. 6. Remove the metal cover on the right side at the rear; this will expose the Magnetron and the Capacitor. Remember to immediately test and discharge the capacitor!
7. After you discharge the capacitor, remove the other cover plate and the support bracket - in case you haven't noticed, this is a time and space consuming operation.
8. You

My combination microwave/convection oven is not heating sufficiently while on convection. I see that the element is getting red and heat come on, however, i noticed that the fan is not working and not moving the heat around sufficiently. Any suggestions on what may be needed to fix this?
For model number KMHC1857WSS0
Hi Debra,
Thank you for your inquiry. It sounds like you will need to replace your fan motor. I hope that helps!

When heating an item, the microwave heats properly for about 2m15 sec. The noise of the magnetron then stops but everything else is working - turntable, timer, light, etc. If i stop the microwave and wait several minutes, i can then set the timer and the magnetron can be heard to be working/heating. After about 45 sec it stops heating again and everything else is working properly. Does this sound like the magnetron or the electric control?
For model number KBMS1454SSS3
Hi Vernon,
Thank you for your question. I would actually suggest you check your diode and your fuse to see if they are both working correctly first. Be very careful when doing any repairs on your microwave. There is a capacitor inside of your microwave that will need to be safely disarmed before you start any repairs or else it could electrocute you. Good luck with your repair.

My previous question was answered but it did not solve the issue. The diode, fuse, capacitor, and magnetron are good so it is something else. Maybe the fan is not working and causing overheating? How to check?
For model number KBMS1454SSS3
Hi Vernon,
Thank you for your follow up. Unfortunately we do not have any information on how to test that fan motor. However I do not think that would be causing your issue. I believe that if all of your other parts are fine, it is likely that your electronic control board is the issue, as that part is the brain of your appliance. I could suggest double checking with the manufacturer if you wanted a second opinion. I hope that helps. Good luck with your repair.

The combo built in oven making constant clinging noise, after a minute or so of turning on and continues making noise even if it's turned off until it's cooled down.( sounding like a loose fan banging the surrounding walls) Is it a malfunction in cooling fan? How difficult or costly is it to repair ?
For model number YKEMS307GB0

Hi the microwave is not heating. Everything else seems to be working. The oven works well and the microwave have light and the dish rotate but doesn’t heat. What part is the one that is not working ? Is the magnetron or an other? Is not making any strange noise.
For model number KEHC309JSS05
Hi Alessandra, thank you for contacting us. We have researched the model and would suggest checking the high-voltage diode, part number PS11757136. It provides power to the magnetron that creates microwaves to heat the food. A defective high-voltage diode may result in a microwave that runs but does not heat the food. We hope this information helps!
