(b)(4).Method: the infant warmer was not returned to fisher & paykel healthcare for evaluation as the hospital had elected to repair the unit themselves.Our investigation is therefore based on the photograph and information provided by the hospital.Results: inspection of the provided photograph revealed that the head harness connector was incorrectly assembled and there was discolouration of the head harness housing connector on the slot where the neutral and phase wire terminal is located.Conclusion: the incorrect assembly of the harness connectors had caused an open circuit.The upper and lower harnesses are used to connect the head unit to the control unit of the infant warmer.Loss of electrical contact will lead to degradation of the harness connector and result in an error 17 condition.From the information provided by the hospital we have noted that the infant warmer harness was replaced in (b)(6) 2011 and the technician incorrectly assembled the harness connector at that time.All components on the harness assembly of the infant warmer are enclosed in a sheath and fire rated by underwriters laboratories (ul).Should the connectors completely fail during the operation, an audible and visual alarm (e17, as reported by the customer) will be registered on the front control panel of the infant warmer, thereby allowing the hospital staff time to act and provide other means of warming.An infant warmer harness spares kit was sent to the customer in order for the biomed to repair the subject warmer unit.
