A:Answer Hello judie - this is Nancy at GE Appliances and I am happy to help you. We're sorry to hear that your Spacemaker over-the-range microwave died, but we are glad to know that you received 15 years of service from your microwave. The good news is that the new microwaves are designed to work in the same cabinet space, even though the dimensions may be slightly different. You will, however, need to use the new mounting bracket and hardware as they have changed over the years and are not interchangeable. I hope this helps! Thanks for checking with us!
