A review of information in the complaint file indicates this investigation was performed by a covidien international service center for the reported condition of; case is broken.Therefore, this report will be based on information provided by the service center.Pictures contained in the complaint file show the power cord is damaged and shows external signs of burning near the end of the strain relief where it plugs into the unit, confirming a defect other than the reported condition.The root cause of failure can be attributed to excessive strain placed on the power cord near the strain relief while it was installed in the unit, which caused the internal wires to break and eventually short.Over time, normal flexing, wrapping the cord too tightly around the bed hook, or supporting the weight of the unit with the cord can cause individual wire strands to break which increases the amount of heat generated by current flow.The continued damage to the cord results in internally broken wires which increases the power cord's resistance, resulting in melting of the wire insulation and potential catastrophic failure.Power cords periodically require replacement due to age, usage and user damage.The service manual instructs the user to periodically inspect the power cords resistance to ensure its electrical safety.Product scd express compression system was manufactured in 2006.This information will be utilized for trending purposes to determine the need for corrective action.
