Product review (5 stars): It was a very easy fix. Quick note to those who are cheap/lazy
This part fixed my issue. The off button stopped working. It was a very easy fix.

Quick note to those who are cheap/lazy. There is a workaround for the off button being broken, you can press 'Cook Duration' then set to '1 minute'. The oven will turn off after a minute. I did this for far too long to admit before finally replacing the part my self. The fix took about 15 minutes.
