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 component are correctly connected. (controller board, motor,
sensor, relay)
Reconnect the connector if it is not connected correctly.
3. Harness damaged
Check if the harness between the controller board and the motor/sensor is damaged or exposed.
