Manufacturer Narrative

Updated block: h6 the reported complaint was confirmed.Per supplier evaluation, the burned capacitor was verified.The capacitor was oriented correctly on the board and there was no visual physical indicator for what may have caused the burning.The capacitor measured low resistance indicating a short did happen.The reason for the short was unknown.The printed circuit board assembly (pcba) had passed all tests and inspections and was fully functional when originally shipped to the manufacturer.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
