On june 24, 2020, the autopulse platform (serial #(b)(4)) was serviced for preventive maintenance (pm).During the functional testing, the autopulse platform displayed user advisory user advisory "(ua)17" (max motor on time exceeded) and "fault code16" (timeout moving to take-up position) error messages.The root cause of "(ua)17" and "fault code16" was due to damaged drive train motor, likely attributed to wear and tear.The autopulse platform was manufactured in november 2015 and is nearing its expected serviceable life of 5 years.The drive train motor assembly was replaced to remedy these uas.Also, the archive data could not be download and load cell characterization test could not be performed due defective processor board, a capacitor was broken on the main board, likely the capacitor over-heated and over time the leg became fragile leading to the breakage.The processor board was replaced, and load cell characterization test passed and archive can be downloaded with no data since it a newly installed component.No physical damage was observed on the returned autopulse platform during visual inspection.After service completion, the autopulse was subjected to the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test battery until discharged without any fault or error.The autopulse platform passed all functional tests.Historical complaints were reviewed for service information related to the reported complaint and there was no previous history of complaint reported for autopulse with serial number (b)(4).
