Daniel Boone/Jim Bowie:
Never just use the ON/OFF switch to turn the grill off. Instead, use the down arrow to lower the temperature to 150. Release the button and press it once again to enter “FAN” mode. The grill will power down after the “FAN” mode ends. At that time, you may use the ON/OFF switch to cut power to the grill.
Just press the red power button at any time to turn the grill off and enter automatic FAN mode.
