Interesting that I'm also experiencing same issue as another recent review here, my three year old microwave is only tripping the circuit breaker to the point where I wasted money on an electrician, who confirmed issue is the microwave. Microwave is completely unusable now and actually caused outlet to spark. To top it off the top vent grill piece fell off and landed on the range, now it is damaged. This appliance is only used by adults at our residence, certainly not worth the price for a malfunctions appliance that has parts randomly falling off it
