A:Answer When looking for an appropriate replacement oven, it's important to understand the dimensions of the actual cutout you have available in your cabinetry as well as the overall dimensions of your existing oven. This model is a double oven microwave combination. It offers a microwave on top and an oven below. The cutout dimensions required for this oven are 41 1/8"(min) - 41 1/4"H (max) x 25" x 25 1/4"W. The overall dimensions are 42 3/8"H x 26 3/4"W. You may wish to consider one of our models with two ovens like the JKD3000SNSS, JKD5000SVSS, or our PKD7000SNSS as their dimensions are closer to what you currently have. We recommend contacting a cabinet company in your area for assistance in what might be needed to modify your existing space to accommodate these models. -Vikki@GEAppliances
