The foot control is a simple device with a resistance value that, as the foot control is depressed, the value diminishes and the machine runs faster. The cause of an immediate run condition will be the result of the following: 1. The cable or plug has been damaged so as to connect both wires to create a maximum run state. 2. Most common to the foot control itself is that the actuator for the slide resistor is broken and stuck in the max run spot as well as having been disconnected from the on/off micro switch. 3. The foot control has been taken apart and improperly assembled. SewTechnical Home
