Abstract
Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a burn pot configured to combust pellet fuel received within the burn pot. The pellet grill further includes an auger configured to deliver the pellet fuel to the burn pot. The pellet grill further includes an auger motor operatively coupled to the auger. The pellet grill further includes one or more processors configured to determine whether a shutdown sequence of the pellet grill has been initiated. The one or more processors are further configured, in response to determining that the shutdown sequence has been initiated, to command the auger motor to reverse a direction of rotation of the auger. The reversal is to cause pellet fuel which the auger has not yet delivered to the burn pot to be purged in a direction away from the burn pot.
