Microwave Displays "Cool" (or "-90" or "-80")

If the microwave displays "Cool" (or on some models the display may show -80 or -90) when using the Temperature Probe, this due to the internal temperature of the food in the oven being below 90 degrees. When the temperature reaches 90 degrees (this may take up to 20 minutes), the internal temperature of the food is displayed as it increases until the oven shuts off automatically.
