Automatic gates provide enhanced security, convenience, and curb appeal—but like all machines, they can occasionally experience issues. Whether you have a sliding gate, swing gate, or boom gate, knowing how to identify and resolve common problems can save you time and reduce downtime.
In this guide, Skyline Gate Automation shares the most frequent electric gate issues and some simple DIY troubleshooting tips to help get your system back up and running.
Most common Automatic Gate Issues:
1. Gate Won’t Open or Close
Possible Causes:
Power supply disruption
Dead remote batteries
Faulty control board
Obstruction on the track or hinges
DIY Troubleshooting:
Check power supply – Ensure your gate motor is receiving power. If you’re using solar, verify the batteries and solar controller are functioning.
Replace remote batteries – This is a quick and often overlooked fix.
Inspect for obstacles – Clear any debris, rocks, or ice around the gate track or swing hinge.
2. Gate Is Noisy During Operation
Possible Causes:
Worn-out rollers or wheels
Loose hardware
Dry or rusted parts
DIY Troubleshooting:
Lubricate moving parts – Use a non-greasy lubricant specifically designed for gates.
Tighten bolts and screws – Check brackets, hinges, and tracks for loose components.
Inspect rollers and wheels – Replace if cracked, flat, or damaged.
3. Gate Remote Not Working
Possible Causes:
Flat battery
Remote not paired
Interference or signal issues
DIY Troubleshooting:
Replace the battery – Most gate remotes use standard coin-cell batteries.
Reprogram the remote – Refer to the manufacturer’s manual or check our gate remote pairing guide.
Test signal range – If you're having trouble at long distances, consider upgrading to a 433.92 MHz booster antenna.
4. Gate Opens or Closes Partially
Possible Causes:
Incorrect limit settings
Obstruction in the gate’s path
Faulty encoder or magnetic limit switch
DIY Troubleshooting:
Reset gate limits – Follow the gate opener’s manual to reset open and close positions.
Check for obstructions – Even small stones or sticks can stop a gate.
Inspect sensors – Clean or adjust the position of limit switches and encoder magnets.
5. Photo Beam Sensor Is Triggering Without Obstruction
Possible Causes:
Dirty or misaligned sensors
Damaged photo eye cables
Sunlight interference
DIY Troubleshooting:
Clean sensor lenses – Use a soft cloth to wipe off dust, cobwebs, or water spots.
Align sensors – Make sure both sensors are directly facing each other.
Check wiring – Look for frayed wires or loose connections.
6. Gate Doesn’t Operate on Schedule
Possible Causes:
Faulty timer settings
Power disruption
Timer failure
DIY Troubleshooting:
Reprogram your digital timer – Double-check the time, date, and programmed open/close schedules.
Inspect the power source – Reset your timer if there's been a power outage.
Replace the timer – If your Digital Gate Timer is outdated or malfunctioning, consider upgrading to a programmable 24/7 model.
7. GSM or WiFi Control Not Working
Possible Causes:
SIM card expired or no data
No WiFi signal at the gate
Power supply to the control device interrupted
DIY Troubleshooting:
Check SIM/data plan – Ensure your 4G GSM gate opener has an active SIM card.
Test WiFi signal – Use a WiFi extender if the signal doesn’t reach the gate.
Restart the device – Power cycle your smart controller and check connections.
Replace the GSM device – If your 4G GSM gate opener is outdated or malfunctioning, consider upgrading to a Volte compatible 4G GSM gate opener.
