Model: JVM3160DF4CC. Review of several online videos allowed me to test microwave components to determine tripping breaker was caused by a door switch that had gone bad; apparently a frequently occurring problem after several years of use. In the process of necking down the problem to the microwave (and not the house circuit), I tested the oven on a different circuit with a less sensitive breaker and blew the fuse in the oven. Both problems were easy to fix. Have relied on APP for parts for this and repairs to dishwasher, dryer, other microwave oven, oven. Over years I have repeatedly purchased from APP. I shop around for parts and eventually come back to them for competitive price, excellent phone support for purchasing, confidence in info on website.
