The customer was sent a replacement power supply and return of the original power supply was requested for testing/evaluation.In follow up with a complaint handler on (b)(6) 2018, the customer indicated via email that the power supply was always hot and for that reason, she would always unplug it after using; that the plastic on the housing was warped and soft, but hardened back up once it cooled down; and that though it was hot on her fingers, it did not burn her, as she dropped it quickly.She also indicated that there was a break in the housing near the prongs and that the replacement power supply was working without issue.On (b)(6) 2018, a complaint handler followed up again with the customer after receiving her response for additional information on (b)(6) 2018 and to clarify whether the customer witnessed fire.The customer responded with "i recall a spark and smell and pop sound" and did not confirm her original report of fire.This issue with a damaged rev m power supply for the pump in style device was addressed in investigation ir12-0037.The investigation found that they were being damaged during shipment from the manufacturer to medela.This damage was causing the plastic housing to fail prematurely when subjected to normal use and foreseeable misuse.The packaging used by the manufacturer to ship the power supply to medela was not robust enough to handle all of the potential shipping, handling, and abuse conditions that could arise from logistics of the consolidation process.As a result of the investigation, the shipping and consolidation process was modified to reduce the handling and potential for double stacking of the skids.The shipping packaging strength was also increased to further protect the power supply during shipping.Since then, as a part of routine continuous improvement activities, a rev p power supply has been distributed to market, manufactured under a revised design and by a different manufacturer.
