A: Before calling a specialized technician to perform troubleshooting for you, check if there is any visual indication that the gate opener is powered on. Do not try to open nor intervene inside the electronics to avoid the risk of electric hazard. Additionally, try to replace the batteries inside the remote controls and test again from a shorter range. Further check if there is any kind of obstacle preventing the operation of the gate. Should you still have an issue, ask a specialized technician to perform troubleshooting for you, to avoid causing further damage to the gate.
