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):

Plugged in display works showing appropriate clock select 30 seconds hit start, sounds like it starts, within five seconds, starts to sputter and spark, and turn off. The first time it did it it just turned off, and there was some sort of a smell, ozone maybe? I then took the metal casing off and try it again and that’s when I saw the spark towards the back.
For model number MS19M8000AS
Hi M, thank you for contacting us. We have found that as magnetron wears out, it may cause your microwave to spark. The magnetron is responsible for creating the microwave frequencies that heat the food. You may need to check the magnetron, part number PS4251299, to fix the issue. We hope this helps, good luck with this repair!
Microwave makes a loud buzzing sound while running. It is still heating food but the buzzing sound is very loud. Seems like it could be the vent fan? Any ideas?
For model number MS19M8000AS
Hello John, thank you for the great question. Based on the description that you have provided, we would recommend checking the diode, part number PS4235633, to fix the issue. It converts alternating current into direct current and can cause the buzzing noise. We hope this solves your problem!
Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.
I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.
Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those w

Now the Microwave works just like new! Cost me less than $100 for all parts.
The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.
You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.
You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi met

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.
When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.
