Microwave issues

[Martinriddle1959]

Hello all, I have a 2017 Grand Design( may not be relevant to my issue). We were have problems with our original microwave. Blowing the internal fuse and door switches. We replaced these items several times, and finally bought a new microwave. Now this one is doing the same thing. I checked the voltage at the dedicated outlet to see if it was the breaker(15 amp). Voltage was good. My question is, even though voltage was good, could the breaker still be the culprit?
