The microwave starts and stops several times while heating or cooking and SELECT and COOK on the touch pad do not respond to touch and hold, so cannot set the time or switch back and forth from DEMO MODE. Other functions seem to work fine...

Hi Hez, thank you for contacting us. To exit demo mode, open the door, then touch and hold COOK for 5 seconds. Three short tones will sound. If the issue persists, you may need to replace the control panel, part number PS12349016. We hope this solves your problem!

Does this microwave have a reset button?
For model number KMBS104ESS02
Hi Margaret, thank you for your question. We have researched the model you have provided and have found that the CANCEL button is used for resetting. Touch CANCEL and reset the oven if needed. The oven can stop responding due to software glitches or unintended microwave settings. If necessary, perform a hard reset by unplugging your microwave for 30 minutes, then plug it back in. We hope this information helps!

The microwave door doesn’t close well and makes a weird noise and doesn’t always heat. We had the door fixed once already.
For model number KMBS104ESS02
Hi Beth, thank you for reaching out. Based on the description that you have provided, we would recommend checking the hinge support, part number PS11701504, and switch holder, part number PS11745281, which might be broken. Also, the diode, part number PS12584264, and the magnetron, part number PS12741756, could be behind the noise and no heat. We hope this sorts out your problem!

Microwave made very loud noise while on. No heat.
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.

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.

Humming sound, not heating.
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!

Microwave glass turntable when pop
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

an 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.
