BASIC TROUBLESHOOTING
To protect against fire and electrocution:
• DISCONNECT power (AC or solar and battery) BEFORE installing or servicing operator.
AC MOTORS
SYMPTOM: The motor will not run.
CHECK THE MOTOR:
Disconnect ALL power from operator. Disconnect the gate from the operator. Unplug the motor harness from the board and measure the resistance of
the motor. Refer to illustrations.
SOLUTION: If the motor measured too much resistance or zero resistance, replace the motor.
