Claim 8:
9. A pellet grill, comprising:
a cooking chamber;
a burn pot;
an ignitor extending into the burn pot and configured to ignite pellet fuel located within the burn pot; and
a controller configured to:
determine a startup temperature of the cooking chamber;
command the ignitor to activate during a first duration associated with a preheating operation of an engine of the pellet grill;
following expiration of the first duration, determine a current temperature of the cooking chamber;
determine whether a temperature difference between the current temperature and the startup temperature exceeds a threshold temperature difference;
in response to determining that the temperature difference exceeds the threshold temperature difference, determine whether the temperature difference has exceeded the threshold temperature difference for a second duration; and
in response to determining that the temperature difference has exceeded the threshold temperature difference for the second duration, command the ignitor to activate.
