When we closed the door the light stays on and there some motor noise that starts. The door open the light is on no motor noise. The microwave will work if I set the timer to cook and the plate will spin. The fan works with the buttons and the noise is still there while they are running. Unplug for a day and same thing when plug back in.

Hello Chris, Thank you for the question. This is normally an indication one or more of the Door Switches is defective and may need to be replaced. They can be tested for continuity with a multi meter. We hope this helps!
Hi Keith,
Thank you for your question. The SE error code means that you either have a stuck key on the keypad or you have a failed electronic control board. Try and reset the microwave by unplugging it for a few minutes to see if this will resolve the issue. If the code reappears, you will need to check the keypad on the control panel. Press the buttons on the keypad. If the buttons light up and the microwave does not respond, remove the control panel from the microwave and disconnect the ribbon cable from the electronic control board. Sometimes a film can build up on it and you can use a pencil eraser to gently remove it. You can also test it for continuity with a multimeter to see if it is working. If the control panel tests fine, reconnect it to the microwave. If the error code reappears, you will need to replace the electronic control board. We hope this helps! If you have any questions, please let us know.

Hi Michelle, thank you for reaching out. Based on our understanding of the issue, it seems that you have not installed the switch properly, we would suggest that you may check again if the switch was installed correctly. If not, we recommend checking the door switch, part number PS11741686, for continuity and replacing it if necessary. We hope this sorts out your problem!
Initially I called a Samsung recommended appliance repair outfit to fix the latch. The technician informed me that he does not fix latches. I need to buy a full new door for the microwave for $215 plus he charges $165 to come to my house. I got angry and did some research and it turned out that this is a very common problem. I ordered par
... Read moret PS4229162 "door key" $6.67 then followed the instructions on a youtube video by zimsjeep "Repair a Broken Microwave Door Latch" to install. At first I struggled a bit hooking up the spring to the frame, but then I used a slim plier to hold the spring (instead of my fingers) and that did the trick.
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.
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.
