My microwave has decided to die due to a bad bulb short as I was changing it. Since then, the microwave has gone completely dead. Nothing on timer screen, won't turn on. I pulled the cover off and replaced the internal fuse then checked all other connections. The plug and circuit breaker fuse are fine, getting constant power. I am at a loss of what else to do to get this thing back working. Can someone PLEASE give me some helpful insight? I really don't feel like buying a new microwave when this is only about 4 years old. I know this has to be something stupid.
