Thomas P Edmnds , WA December 04, 2015 Appliance: Samsung Built-In Microwave Oven SMH9207ST/XAA-0001 Samsung Microwave Smh9207st/Xaa-0001 / : The select buttons on my samsung microwave broke. How to replace Microwave Select Button. I had a great experience fixing this myself. The fan button broke due to a very poor design. The button is made of plastic and is held in place by a 1/32 inch connection to a plastic frame. Very easily broken. The part was available, gaining access wasn't hard and actually kind of fun. The connections weren't complicated. Total repair was less than an hour and saved the microwave from the scrap heap. The only obstacle I found was getting a good diagram of how the facia of the microwave came off to gain access. However the internet showed a pretty good picture.
