A:Answer Hi SEMBEL - We are sorry to hear of the difficulty with your microwave. For best operation, plug this appliance into its own electrical outlet to prevent flickering of lights, blowing of fuse or tripping of circuit breaker (120 volt individual, properly grounded branch circuit with a 3 prong grounding type receptacle, protected by a 15 or 20 amp circuit breaker or time-delay fuse). Do not use an extension cord. You can also schedule an appointment with GE Appliances Factory Service at GEAppliances.com/service - GE® 1.6 Cu. Ft. Over-the-Range Microwave Oven JVM3160DFCC is a current model and the only GE model offered in bisque. All 30" over-the-range microwaves are approximately the same width, and are designed to fit into a 30" wide cabinet opening. Therefore, any of our 30" over-the-range models will work as a replacement for an existing 30" over-the-range model. Keep in touch! Sue
