Vending machine control and diagnostic apparatus for a vending apparatus having product delivery means comprising an electrically operated actuator for delivery of products, an impedance element and a circuit opening switch. The impedance element and the switch are connected electrically in series with each other and in a parallel circuit with the actuator, and the opening and closing of the switch is controlled by the operation of the actuator. The control and diagnostic apparatus detects changes in impedance of the parallel circuit.
