A:Answer There's 2 measurements to worry about. First, is making sure your new oven fits in the existing hole, or the hole can be enlarged without weakening the cabinetry. These are horizontal, vertical and depth measurements that you can compare to the new oven requirements. This is critical and not obvious how to do accurately. Second, is to make sure your existing electrical circuit and breaker are large enough for your new oven. If it is not, you may need to hire an electrician to rewire the ckt to your oven. The first oven I chose (LG) was too big so I cancelled it. I had to get a smaller unit like a kitchenaid or a GE.
