A:Answer Hi Conure18, thanks for your question! Preheating is very important when baking at temperatures above 275 degrees or when baking items with short cooking times, such as cakes, cookies, biscuits and other pastries. Although preheating is not needed for meats, poultry, casseroles, when roasting or when cooking complete meals, it is recommended. During Preheat, the Bake and Broil elements come on to quickly heat the oven. - Some ranges and wall ovens have Preheat indicator lights or have a Preheat signal to let you know when to place the food in oven. There are two types of Preheat: 1. Preheat signals when the set temperature is reached: This is found most often on models with a preheat indicator light, but also on some models with a beep. Preheat takes approximately 10-20 minutes depending on model. 2. Preheat signals when the temperature is hot enough to add food: Found on newer models with an audible Preheat signal. Preheat will signal at about 5-7 minutes. The oven is not at the set temperature; however, the oven is hot enough to add most items that require a pre-heated oven. - For those models that do not have a Preheat indicator light, wait approximately 10-20 minutes to allow oven to preheat. Time will vary depending on your model. We hope that this helps! All the best. -Michael
