This DIY repair guide shows how to replace the motor centrifugal switch on a trash compactor. The motor centrifugal switch controls the direction of the drive motor, which moves the ram up and down to compact trash. If the switch breaks, the ram travels down but won't move back up. Replace a broken motor centrifugal switch with the manufacturer-approved replacement part.
