This one smoked! Turntable kept turning, internal light stayed on, control panel is ok, vent fan & under light still worked. Stopped heating. Strong smell of burnt polymers in thick blue smoke. Guessing power control pcb, xfmr, hv cap or magnetron? Or all of the above??
For model number SMH1816S
Hello Nathan, Thank you for the question. This normally indicates a faulty Magnetron. We suggest testing the Magnetron with a Multimeter. The magnetron can be tested with an multi meter set on the highest scale. Across the terminals, you should read 0 ohms (or .5 ohms). Test both terminals to ground with one lead and make sure it is not shorted. We hope this helps!

Ok. So, across the element terminals should be roughly 0- 0.5 ohms. But from either terminal to ground (or shell) should be open correct?

Microwave door did not close
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

"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.

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 met ... Read more er. 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.
