Gate not closing? Remote stopped working? Motor running but gate not moving? We walk through the seven faults our engineers see most — and what to do.
1. Remote Control Range Has Reduced
- *Likely cause:** Battery in the remote is low, or the receiver antenna is damaged.
- *Fix:** Replace the remote battery first. If range doesn't improve, check the antenna wire on the control board is intact and fully extended.
2. Gate Opens But Won't Close
- *Likely cause:** Safety sensor (photo-electric beam) is misaligned, dirty, or faulty.
- *Fix:** Clean both sensor heads with a dry cloth. Realign them so the beam is unobstructed. Most boards have an indicator LED that confirms beam status.
3. Motor Runs But Gate Doesn't Move
- *Likely cause:** The drive mechanism is disengaged (manual release mode) or the rack/chain is broken.
- *Fix:** Check that the manual release handle or key has been returned to "auto" position. Inspect the rack for broken teeth.
4. Gate Reverses Immediately After Starting
- *Likely cause:** Obstruction sensor triggered, or motor torque limit set too low.
- *Fix:** Remove any obstruction. If clear, increase the force/sensitivity setting on the control board (refer to your manual).
5. Gate Moves Slowly or Stops Mid-Cycle
- *Likely cause:** Low battery backup voltage, or motor overheating after many rapid cycles.
- *Fix:** Test the battery voltage with a multimeter — should be 13.5V+ (12V system). Allow motor to cool before further operation.
6. Intercom Works But Gate Doesn't Open
- *Likely cause:** Relay contact between intercom and gate board has failed.
- *Fix:** Test the relay output with a multimeter. Most intercoms have a dry-contact output — check wiring continuity to the gate board's trigger input.
7. Gate Vibrates or Makes Grinding Noise
- *Likely cause:** Worn rollers, loose mounting bolts, or lack of lubrication.
- *Fix:** Lubricate all moving parts. Tighten all visible bolts. Inspect rollers for flat spots and replace if needed.
