ME21DG6500SRAC Samsung Microwave

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 initially thought I needed a new touch control panel but after a bit of research on the web and numerous videos and articles on replacing the control panel, I found an obscure video and forum where they mentioned that this thermostat fuse has been known to overheat and shut down the oven (touch controls) for safety reason. By the way, ... Read more my unit is 3 years old and the warranty expired one month ago! I took the top off, found the fuse and tested it with a Multi-meter (again, thanks to some very helpful youtube videos out there). Dead. I figured it was worth a try and ordered the $20 part as opposed to the much more expensive control.

*** You do NOT have to remove the front piece as some videos and articles mention.
The total time should be about 20 minutes. With a little patience and pre-homework, it's easy and you'll save a couple hundred in labor costs.

Good Luck.

I removed the body latch assembly and found the bottom micro switch (NC) terminal burnt and loose. I replaced and working perfectly fine now. Easy diagnose and easy repair.
