A:Answer Hi Homeowner, thanks for your question! We're finding that your old wall oven has the following cutout requirements: Cabinet width: 24", width (max): 22", height (max): 28 1/8", depth (min): 24", bottom of cutout space from the floor: 32 1/2". - For the new oven that you've provided here, the cutout requirements for it are as follows: Cabinet width: 24", width (min): 22 1/2", height (min): 27 5/8", depth (min) 23 1/2", bottom of cutout space from floor: 32 1/2". Some slight modifications may need to be made to your cutout space. We would recommend speaking to a contractor or a cabinet professional for help with any modifications to the cutout space. We'd also recommend speaking to Best Buy about installation and cost of that service. We hope that this helps! Stay safe. -Michael
