I pulled it off the wall and opened it up ( unplugged ) Then I checked the fuses with my volt meter and found nothing wrong. I then checked the capasator and found that to also be good, I then plugged in the Microwave and tried a test run and noticed the fan was not running. I unplugged the fan and tested to see if it was getting voltage and it was.....soooo the fan was bad. I ordered the new one and the microwave now works.
