How do you preheat convection micro oven?

You can't preheat a convection microwave oven in the same way you preheat a conventional oven.

Here's why:

* Microwave ovens work by using electromagnetic radiation to heat food. They don't use the same heating elements as conventional ovens.

* Convection microwaves use a fan to circulate hot air. This helps to cook food more evenly.

Instead of preheating, here's what you can do:

1. Set the desired temperature and cooking time.

2. Start the oven.

3. The oven will automatically heat up to the desired temperature. This usually takes a few minutes, depending on the model.

Tips for using a convection microwave oven:

* Use a recipe designed for a convection oven. Regular microwave recipes might need adjustments for convection cooking.

* Start with a slightly lower temperature than you would use in a conventional oven.

* Check food frequently during cooking. Convection ovens can cook food faster than traditional ovens.

* Use a cooking thermometer to ensure your food is cooked thoroughly.

If you're unsure about how to use your convection microwave oven, consult the owner's manual. It will provide specific instructions for your model.
