If I shut the door on the microwave too quickly it will trip the main circuit breaker 20 amp. If I gently close door the microwave will work and heat. Have checked the four switches associated with door and all seem to open and close when manually tripping the switch. Initially found that the main fuse 20amp was blown and replaced. Now the main fuse is ok but the main 20 amp breaker is being tripped. Have looked for loose or burnt wires everything appears fine.
