Why does the preheat progress bar not start from the beginning?
When the unit is warm from previously being used, it will not require the full preheating time.
My food is burned.
Do not add food until recommended preheat time is complete. For best results, check progress throughout cooking, and remove food when desired level of brownness has been achieved. Remove food immediately after the cook time is complete to avoid overcooking.
Why is my unit skipping temperature?
The temperature goes up by increments of 5.
