The manufacturer received the bipap, heated humidifier, power supply and only partially intact ac power cord for investigation.The manufacturer confirmed that a thermal event had occurred at the male end of the ac power cord, allowing exposed wires.The power cord could not have been placed into use after the event.Because the power cord was not fully intact, no root cause could be determined, although poor physical connection between the ac power cord and ac wall outlet is likely.No further action is necessary.
