Solution
1. Motor/sensor defective
Check the motor (whether it rotates on its own, whether its drive is transmitted, or if it is
overloaded). Check if the sensor turns off and on.
If the motor or sensor is not good, replace it.
2. Connector not connected properly
Check all the connectors of each motor and sensor are correctly connected. (controller board,
motor, sensor, relay)
