A:Answer Hi - Thank you for your interest in a new GE Appliances double wall oven with microwave. In comparing the cut-out requirements for your existing model and for the new model, they are the same. You can view the details of the needed cut-out dimensions needed for the new model, take a look at page 3 of the installation instructions here -- https://files.bbystatic.com/qDuZWne6GUZW%2B5%2B3poxXbg%3D%3D/30e24101-947e-4b5b-97e3-06a6c5dff173.pdf -- To make sure there are no surprises, we recommend measuring the actual opening you have available in your cabinetry and compare it to the dimensions needed for the new model. Please let us know if you have additional questions. Kind regards - Vikki@GEA
