Before calling for a repair, there are a few simple checks you can do that might help identify the issue. This guide walks you through safe and common-sense steps for diagnosing common electric gate problems.
Safety First:
Electric gates can be dangerous if not handled properly. Never attempt to repair internal components unless you're qualified. Always turn off the mains power before opening any control boxes, and if you're unsure- stop and call a professional.
Check if other electrical devices on the same circuit are working (outdoor lights, etc.).
If your gate has a display panel or status lights on the control box, are they on?
If you have an accessible fused spur or circuit breaker dedicated to the gate, check it's not tripped.
Note: If you're opening the control box to check for lights or fuses, switch off the mains power first. There may be live components inside.
Most automatic gates have safety beams (photocells) that stop the gate from closing if something crosses their path.
Look for small black boxes positioned facing each other across the gateway.
Make sure they're clean and aligned — a misalignment or spider web can block the signal.
You may notice a small LED indicator on one side; this should stay lit when the beam is uninterrupted.
Some photobeams actually stop the gate from opening, especially if it’s opening up to a narrow space.
Safety edge sensors, if activated or damaged, will stop a gate moving completely. They usually make the control board clik when activated, so if one makes a click but another one doesn’t then it may have an issue.
Tip: A blocked or faulty sensor is one of the most common reasons a gate won’t close.
If the gate tries to move but makes a grinding, clicking, or humming sound, this could point to:
A mechanical jam
Motor strain or damage
Low oil in hydraulic motors
Capacitor damage
Don’t force it — repeated attempts can cause further damage. Make a note of the sound and when it occurs.
Try using other gate triggers to confirm if the motor is at fault or if it’s just a control issue.
Test with a spare remote if available — the battery may be flat.
If you use a keypad or intercom system, test the gate from each entry point (remote, keypad, phone app).
Check along the gate path for any sticks, stones, or debris.
Look near the hinges and track (for sliding gates) or gate arms (for swing gates).
Even small objects can trigger a fault or safety lockout.
High winds can activate safety sensing as the gate may ’think’ an object is detected.
Watch Your Step: Tools, boxes, or leaves can create trip hazards. Keep the area tidy and well-lit during checks.
After storms or heavy rain, water ingress can trip safety systems or damage sensors.
In cold weather, gate hinges or motor gearboxes can freeze or stiffen up.
If this is the case, you may need to wait for conditions to improve — don’t force the gate.
Still Not Working?
If your gate still isn’t responding after these checks, it’s time to call in a technician. Make a note of:
What happened before it stopped working
Any flashing lights or error codes
What you've already checked
This can help speed up the diagnosis and get things working again faster.
Manually release your gate
You will have received documentation showing how to put the gate into manual mode so you can open it to get yourself in or out.
If you are part of a managed shared residence, apartments or shared access then you may need to contact your agent, they will have the manual release instructions and the location of the key (if required).
