I actually dont know the model.
Still i assume not opening is not moving at all? if you open the gate manually does it close?
The clicking sound tells me that at least one internal relay is beeing activated.
With that i would check the IR sensors first.
Then the motor conections and if there is voltage on them when you press the remote and the clicking happens.
The relay will close a circuit to activate the motor, (DANGER) since i dont know the circuit the relay could provide 12 volts up to mains voltage, if you dont have electrical/electronics knowledge dont do it, find a professional to do it for you.
If the motor gets power when the relay clicks could be the motor, motor capacitor (some motors work at mains AC voltage and use a big, normally white capacitor for startup) or the gear box, i've fixed a few garage door and gate systems just by dismantling the gear box, reajust and lubricating them.
Hope it helps
