Factors affecting preheating time

  • Do not open the door of the oven during preheating. It will lose its heat. Place the food right after the oven has achieved the preheating temperature.
  • Large oven cavities can also contribute to longer preheating times.
  • A hidden baking element in your oven that is providing the buffer heat might also be the cause of extended preheating times.
  • If you installed the oven on a lower voltage, It will take longer to preheat as compared to the oven installed on a higher voltage.
  • Room temperature plays a key role in preheating times. A lower room temperature, such as in winters, will lead to a longer preheating period.

  1. Turn the oven on and adjust the temperature and set the timer.
  1. Wait till the oven gets preheated. It is indicated by the switching on and off of a light. Some ovens beep when they are ready while others rely on an oven thermometer placed inside the oven.
  1. Place the food in the oven and do not open the door in between the baking. If you are baking multiple dishes at a time, staggering the dishes so that hot air evenly bakes all of the dishes is the way to go.
