Microwave functions all work but water/food does not heat up.
For model number ME18H704SFS
Hi Robert. I would test the high voltage diode, thermostat and door switch. Thank you for your question and good luck with your repair.
Hi Bob, thank you for your question. For an issue like that you may want to take a look at your door switches for being the issue. If they are fine then it might be your board that is the problem. Good luck with your repair.

For model number ME18H704SFS
Hello Richard, thank you for reaching out. We would recommend making sure that the turntable is not damaged, and it is installed correctly. If the problem persists, then you may need to check the turntable coupler, part number PS4231581, to solve the problem. It connects the turntable motor to the turntable tray to rotate the tray. We hope this helps!
My microwave just stop working, it’s just about 9 mouths since I got it, does it come with a fuse I could change?
For model number ME18H704SFS
Hello Selwyn, Thank you for the question. This model does not list a fuse sorry, however I suggest testing the Door Switches Part #: PS4225460 and Part #: PS4131192 (2 required). You can test the switches with a multi meter to check continuity. Hope this helps!
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.
