Microwave Randomly Trips Circuit Breaker

The microwave in our kitchen trips the circuit breaker at random. We can be using the microwave for five days, and it won't trip it. Then, we can just close the microwave door, at other times, and that will trip it. We have a 10A circuit breaker.


Can I change that one for a 15A? I've already replaced the 10A once and it still continues to do the same. We've isolated the problem to one outlet; there's two outlets connected to that circuit breaker, but there's nothing connected to that second one, it's outdoors. And, there's nothing else connected to that outlet or circuit breaker.

Any assistance would be great.

A Microwave should be on it's own 15a breaker. Most MW manuals tell you this. A 10a breaker will act as you mention.

You can change to a 15a breaker if you are sure the wire to the breaker will carry the 15a or more amps.

You would do well to change it to the outside outlet circuit if the rules above are followed. As an outside outlet would not likely to be used as much and an inside outlet on the same circuit.
