SMH1816WXAC 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.

The part should have just been pulled up and out, mine was broke off so I had to drop the bottom tray and push the remaining old coupler up and out. I dropped the new part in and reinstalled the bottom tray. It was also a good time to clean the tray

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

Got the part and replaced it. Simple. Pleasure to work with

Ordered (most difficult part of repair, because I wasn't sure the one I ordered would fit), opened box, removed padding, opened microwave oven door, lined up center indentations with center and my repair was complete. Placed a cup of lukewarm coffee on the tray, closed door and pushed auto 30 seconds. The cup went round and round on the plate that went round and round and then, the END chime sounded. Success! Lukewarm coffee has been transformed to HOT coffee on the newly installed cooking tray.

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!

I ordered a replacement piece. Fits perfectly and rotates as it should. It arrived earlier than planned.

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.

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!
