SMH6165STGXAA Samsung Microwave - Instructions

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 part 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.

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.

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.

Unplug micro, Remove 6 bottom pan screws, remove pan. Remove 1 screw holding motor, slide motor over and down, and unplug.
Remove coupler upward, slide of center to remove.
Install new coupler, insert motor in coupler slide in place and install screw.
Plug in microwave, place cup of water microwave to the side and test, if working OK, install bottom pan.

By removing one phillips headed screw, a metal frame pivoted down for easy replacement of glass plate.

Searched for a YouTube video that included “replace Samsung microwave body latch” (whatever part name). There are plenty of easy how-tos.

you had the part I am happy , Thanks

Pulled the filters down, measured and went on line- done. was fast to find the part and easy to order...

easy to install

REPLACED DOOR SWITCH ASSEMLY

I unscrewed one screw and droped the glass light bulb cover, bent the light bulb up so it wouldn't break the glass again, removed the broken glass and installed new glass by bending the tabs over the glass to hold it in place and re-inserted the cover, then screwed the retaining screw back in. Done in 3 min.. PartsSelect.com seems to be one of the few online parts ordering place that has schematics and easy to navigate site. Perfecto!

We did not use the part, the spring fell off inside the door. We kept the part just in case

I took off the inner plastic frame of the door, removed the broken part, hooked the spring up to the new latch and replaced it into the proper alignment holes, and works perfectly. It was less than a 5 minute repair.

We just order the tray and basically replaced it with the new one we ordered. It fits perfectly. Very happy with the purchase.
