A combination timer and controller for a gas-operated appliance, such as a pizza oven, is provided. The combination includes a rotatable control shaft having a first end connectible to a gas valve and a control knob attachable to a second end of the control shaft. A timer can be preset to a selected time at which the control shaft is to be turned from an off position to an on position. An actuator motor is provided to turn the control shaft to the on position and it is controlled by the timer so that the motor is turned on by the timer at the selected time. There is a gear arrangement for connecting the output of the motor to the control shaft and a coil spring for rotating the control shaft to the off position when the motor is turned off.
