Stainless Kenmore Microwave - How to replace fuse

I have a Stainless Kenmore Microwave Oven, model number 81043.When I pressed the START button, it was blowing my circuit breaker. So i tried in different outlet, the microwave turned on and went dead. But didnt blow my circuit breaker. So I am thinking the fuse inside had blown.Appreciate your help to replace the fuse or to repair the issue.

Thanks in advance.
