Check the Display

The first step to determine if your air fryer is on is to check the display. Most air fryers have a digital display that will show the temperature and time settings. If the display is lit up, then the air fryer is on. If the display is not lit up, then the air fryer is not on.

Listen for the Fan

Another way to tell if your air fryer is on is to listen for the fan. Most air fryers have a fan that will turn on when the air fryer is in use. If you can hear the fan running, then the air fryer is on. If you cannot hear the fan running, then the air fryer is not on.
