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
