Abstract: An apparatus for temperature control of a barbecue oven, in accordance with an exemplary embodiment of the present disclosure. A vent from a firebox feeds heated air with smoke to a cook box. A variable speed motor connected to a blower wheel draws air out of the cook box into a plenum, and also pressurizes the plenum to force air back onto the cook box through one or more vents between the plenum and the cook box, as well as out of the stack. A variable frequency drive is coupled to the variable speed motor and a proportional-integral-derivative (PID) controller, which is coupled to a temperature sensor. When the temperature falls below a set point, the PID controller causes the variable frequency drive to actuate the variable speed motor and draw heated air into the cook box from the firebox. The blower wheel and vents circulate the heated air in the cook box, and the air exhaust through the stack allows heated air to be drawn into the cook box.
