Main Actuator
The actuator can often be repaired internally, and direct fused-power testing can help isolate failures.
Just about everyone is familiar with the main actuator. What is not common knowledge to most people is that the actuator can be disassembled and that individual components can be repaired or replaced.
Parts that can fail inside the actuator
- Motor
- Gear reduction unit
- Rev counter board
- Drive screw
- Drive nut
The drive screw and drive nut rarely fail, but they should still be kept in mind when the actuator is disassembled.
Testing guidance
Troubleshooting this component properly requires some electrical understanding. For those of you who have this knowledge, one can connect a fused power source to the actuator directly and run it in both directions.
If this explanation is not enough information to give you the confidence to test this component safely, consider hiring a qualified electrician or gate-service professional to troubleshoot it.
