Microwave would not start when door closed. Sometimes you could push in or jiggle door and it would work for awhile and then it woud stop again. I knew it eas a door switch issue but wasn't certain which of the 3 or the body latch itself.
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.

microwave ran with the door open
First I read through the customer comments, reviews, questions, etc. at Parts Select, which is always a good bet. Then I put "samsung microwave door switch replacement" into youtube and watched some videos. They don't even have to be for Samsung. From what I can tell, many of the appliance companies use the same design and the same junk parts, so watching a GE video is almost the same for example. Watch some videos to familiarize yourself with the steps. There are maybe six to disassemble and install the new part. I replaced all three switches. They are not expensive and to replace 3 is only 5% more work than to replace just one; you have to take the microwave apart in either case. UNPLUG THE MICROWAVE FROM THE WALL. Start taking it apart. I use my phone to take a picture of any thing I remove, unscrew or disconnect, especially wires, BEFORE I disconnect them. Thee pictures serve as a reference when I go to reconnect and reassemble. If I am uncertain then I check the picture. Good luck!

Turntable started turn when door opened, then unit wouldn't run when start was pressed
Unplugged the unit. With a screwdriver removed two screws on the top plastic vent. This exposed the screw holding the control panel. Removed that screw to access the switches. Removed the visible connected wiring from the switches. Grabbed each switch with pliers to gentle pull them from their holders. Inserted new switches and reconnected wiring, ensuring the correct orientation of switches in their holders.
Recommend replace all three switches.

Micro kept running when the door opened.......NOT GOOD
After minimum research, it was identified as a micro switch in the door. There is a total of 3, The top and bottom switches are the same in the odd one is in the middle just above the lower switch. Problem i had was one of the you tube videos said to grab the switches with pliers and force them out.;not a good idea. it breaks the lever in the switch holder bar. Solution is to remove the plastic switch holder bar from the door frame removing the 2 screws on the inside of the frame and then you can flip the lever in the bar which secures the switches on the door side. Use a small screwdriver to release the lever and they will slide right out. FYI the plastic switch holder bar is no longer available. I used electrical tape to secure my switches since the levers were broken from forcing them out.

Good Luck

Our microwave would turn on after the timer was set but only the light would turn on, nothing else.
I replaced all 3 door switches. Once you remove the top vent then remove the panel. Then remove the two screws holding the door switches in place and pop them out and replace them. It was tricky getting around all the wires but eventually was able to get around them. Took less than 20 mins to do and was less than $40 to fix. Much better than having to replace our over the stove microwave.
