Buzzing noise, no heating of food
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.

Appears to work, but food not heated
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 meter. Search for the procedures on YouTube.
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.
In the end I ordered a new microwave.

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!

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.

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.
Recommend replace all three switches.

The microwave would not turn on or would run with the door open
Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

Received Broken Part
This is the 2nd broken part that I have received in 2 weeks. You cant install something that is broken. I spoke with customer service and advised that they not send the part in a soft pouch.

Can't Install Broken Parts
This is the second time that I received the same part broken because of poor packaging at the factory. When I spoke with customer service after the first one arrived in pieces I suggested that they advise the shipping department to change how they ship delicate parts. Nothing changed. Same result.

Microwave stopped working - would not heat up
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 were a little more complicated but still easy to do.
Now the Microwave works just like new! Cost me less than $100 for all parts.

CANNOT INTALL A BROKEN PART
I ORDERED THIS PART AND IT CAME SEVERAL DAYS LATER AND IT WAS BROKEN. I SENT IT BACK WITH A BIG NOT SAYING A REPLACEMENT PART MUST BE IN A BOX FOR SHIPPING. THE SECOND PART CAME, NO BOX, AND IT WAS BROKEN. SO AFTER THREE WEEKS PLUS IT IS IMPOSSIBLE TO DO ANY INSTALLATION. I THINK THE SHIPPING DEPARTMENT IS BROKEN AND NEEDS SOME HELP.

Cooking tray shattered
My daughter was trying to run the microwave timer and ended up nuking the cooking tray, which shattered. First web place I found wanted 55$ for this tray and this site sold it for 19.99. It shipped super quickly. I am very pleased with this company!
