My Sharp microwave completley quit. No light, clock, turntable, or power to microwave itself. I turned it on and it gave a funny sound and went out. have checked breakers and unplugged and plugged back in and nothing. Is this something I can fix or do I need to replace it? If it needs to be replaced I need the dimensions to find another to fit over my stove/oven. If it needs to be replaced is there a discount code to buy another sharp microwave? Please let me know Janet ctbhome@sbcglobal.net
