We’d like to provide information about your range, and assist with the issues you’re having with preheating and baking. As your new range likely has a different cooking system than your older model, we do expect it to cook a bit differently. This is discussed on page 25 of the manual, linked here: https://products-salsify.geappliances.com/image/upload/s--PkgVyVpP--/bf6b0c32b639c98fd27d18c7eb0b4a8abec66651.pdf. That page also discusses what to adjust if food isn’t baking as you expect it to.

Regarding the heat varying, the oven elements are designed to cycle on and off throughout the cycle, and the temperature is expected to vary by up to 30°F higher or lower than the set temperature. The goal is to maintain an average set temperature. More information about what to check if you think the oven temperature isn’t correct is available here: https://products.geappliances.com/appliance/gea-support-search-content?contentId=19172.

Regarding the preheating time, multiple factors including the room temperature and number of racks in the oven can affect how long that takes. As your range is taking longer than expected to preheat, we recommend turning off the circuit breaker for the range for a couple of minutes before turning it back on, to reset it. More information is available at this link: https://products.geappliances.com/appliance/gea-support-search-content?contentId=16540.
