You can use the wire shelf, baking pan, and the roasting rack that came with your 1st generation June Oven with later June Ovens.
We do not recommend using the crumb tray as it will affect the oven's performance and does not fit underneath the heating elements as easily. The Food Thermometer that came with that oven will not work on later June Ovens.
Please note that your food might have different results if you use the 1st generation's baking pan as the Cook-Programs are only designed for the 2nd generation's baking pan.
