Hello, We're sorry to hear that your microwave quit working only after six months. If the microwave shuts down during a cooking cycle and appears to have no power, check the circuit breaker or fuse in your home that supplies power to the microwave and make sure it is on. We recommend referring to the troubleshooting steps at the link below: https://products.geappliances.com/appliance/gea-support-search-content?contentId=18780 If the issue continues to persist we recommend scheduling an appointment with our factory service and repair team by calling 1-800-432-2737, or by visiting https://www.geappliances.com/ge/service-and-support/service.htm Let us know if we can ever be of assistance and we’ll be happy to help. -Charlie@GEA
