Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):

Our Microwave makes clicking sounds but won't heat up, the tray spins, the timer counts down but it will make quick clicking sounds then turn of in a few seconds, seems like something is not "firing".
Relay? Capacitor? Diode? Magnetron?
Any advice would be helpful. Thanks, Tim
For model number KMBS104ESS01
Hi Tim, thank you for getting in touch. According to our research, the high-voltage diode, part number PS12584264, needs to be replaced. The diode converts alternating current to direct current for the magnetron. If it fails, the magnetron won't receive the correct power for optimal functioning. We hope this solves your problem!
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.
I turn off the income electricity by shutting down the corresponding circuit breaker. Then, I removed the control panel from the microwave which gave me access to the capacitor and adjacent diode. After that i unscrewed the defective diode and replaced it with the new one and BINGO!
After popping the last few kernals of popcorn, we hear a different kind of pop sound come from our microwave oven. When we looking inside, we found that the glass turntable had broken unevenly in half. Although we didn't understand why it had happned, we did know we'd be without the use of the microwave without a new one. After less th
... Read morean 10 minutes surfing online, I had found the correct part on PartSelect.com and had arranged to have it shipped to me by speedy delivery. Once it arrived, I just popped the new turntable into the microwave and used the box to dispose of the broken one. It could not have been easier and it saved me the cost of a service call and likely further delay.
