Reassemble oven in the reverse order as in the first steps.

Test the oven for good functionality. The fan will come on after a few minutes of (pre-)heating so wait until that occur. Ensure the fan air is being pulled into the unit. If installed backwards, the Foodi will stop after about 10 minutes with ERROR 1. A good test is to run a complete cycle for 15 minutes on Air Fry at 425F.
