Trips corcuit breaker when door is opened...

I had a problem with the bottom door switch. I replaced the switch. Now when the microwave is running and you open the door it trips the circuit breaker. Other wise the unit works fine.

5 The primary switch sends a "latch" signal to the computer; it can feed power only to the internal light and the secondary switch. When the door is closed, the secondary switch should pass power to the fan, platter motor and magnetron. The tertiary switch should short out the magnetron when the door is open. If the secondary switch has burned open, only the internal light comes on when you run the oven. If the secondary switch has shorted closed, the breaker pops like yours does. - avid0g

5 The switches should open and close in a specific sequence and separation in time as the latch moves. Replacing only one switch (instead of all three) with a generic or alternate brand may affect the precision, blowing the breaker. - avid0g
