From time to time we have customers telling us that they are getting an 08H error code on their display and motor won’t run. We have tested many motors and never found a faulty hall sensor. If this happens to you, try unplugging the Pedal Sensor (PAS). The black connector inside the controller housing. We are finding that when you do this the 08H problems goes away. If that is the case for you, just replace the PAS circuit. We suspect that some of these circuits are pulling down the 5v power circuit in the controller triggering the hall sensor error 08H.
