What Is an Electric Colorbond Gate?

Before jumping into repairs, it’s important to understand what we’re dealing with.

An Electric Colorbond Gate is a metal gate constructed using Colorbond steel panels and powered by an automated gate motor. It can be a sliding gate, swing gate, or telescopic system and is typically controlled via:

• Remote control

• Keypad

• Smartphone apps

• Intercom systems

While Colorbond steel itself is highly durable and rust-resistant, the automation components—motors, control boxes, wiring, sensors—require occasional maintenance and repairs.

Most Common Issues with Electric Colorbond Gates

Let’s explore the top mechanical and electrical problems homeowners face with Colorbond gate automation.

1. Gate Not Opening or Closing

Symptoms:

• Gate doesn’t respond to remote

• No movement at all

• Clicking or humming sound from motor

Possible Causes:

• Power supply is off or disrupted

• Faulty motor or internal fuse

• Broken remote or flat battery

• Control board failure

How to Fix It:

• Check if power is reaching the gate motor (inspect circuit breakers or power outlets)

• Replace remote battery

• Test the gate motor with manual override

• Reset the control board if accessible

Pro Tip: Use a multimeter to test voltage output from your power source to the motor.

2. Gate Moves But Stops Halfway

Symptoms:

• Gate starts to open but then freezes

• Stops mid-track and won’t respond

• Requires a push to continue moving

Possible Causes:

• Physical obstruction on the track

• Damaged rollers or bearings

• Faulty limit switch or misalignment

• Dirt or corrosion on the motor gear

How to Fix It:

• Inspect the track and wheels for debris, stones, or insects

• Lubricate hinges or rollers with a silicone-based spray

• Check for bent components (particularly on swing gates)

• Reset the limit switch and ensure correct calibration

3. Electric Gate Is Noisy or Jerky

Symptoms:

• Grinding, squealing, or clunking sounds

• Jerky or inconsistent movement

Possible Causes:

• Dry or rusted hinges/rollers

• Loose mounting brackets

• Worn motor gearbox

• Debris in the gate track

How to Fix It:

• Tighten all bolts and fasteners

• Clean the track and remove any rust

• Apply lithium or silicone lubricant to moving parts

• Have the motor inspected if noise persists

Note: Avoid using WD-40—it may strip protective coatings on motor parts.

4. Remote Control Doesn’t Work

Symptoms:

• No response when button is pressed

• Only works when standing close to the gate

• Works intermittently

Possible Causes:

• Flat or weak battery

• Signal interference from other wireless devices

• Damaged receiver or control panel

How to Fix It:

• Replace the battery in the remote

• Check for new Wi-Fi routers or nearby devices causing interference

• Reprogram or re-pair the remote with the gate system

• Inspect and clean the receiver antenna

5. Gate Opens or Closes On Its Own

Symptoms:

• Gate moves without input

• Opens randomly throughout the day/night

Possible Causes:

• Electrical short or faulty wiring

• Malfunctioning logic board

• Interference from nearby remotes on same frequency

How to Fix It:

• Disconnect power for 10 minutes and perform a system reset

• Inspect all wiring for moisture or wear

• Consult a technician to reprogram the frequency or change the security code

6. Power Outages Disable the Gate

Symptoms:

• Gate becomes inoperable during blackouts

• Emergency manual release doesn’t function

Possible Causes:

• No backup battery installed

• Jammed manual override lock

• Corroded control panel from weather exposure

How to Fix It:

• Install a 12V or 24V backup battery system

• Keep the manual release key in a known, accessible location

• Inspect waterproofing of the control unit to avoid future corrosion

Melbourne Tip: If you’re in an area prone to storms and blackouts, consider upgrading to a solar backup system or UPS (uninterruptible power supply).

Colorbond-Specific Gate Issues

While Colorbond steel is low-maintenance, your gate may develop issues due to:

Paint Peeling or Rusting

• Often caused by poor welding or installation

• Can occur near bolts or joints where water collects

• Repaint with Colorbond-compatible paint and rust primer

Warping or Bending Panels

• Usually due to strong impact or extreme weather

• Replace individual panels without replacing the whole gate

Squeaking Panels in Wind

• Panels may not be secured properly to the frame

• Tighten brackets or use foam inserts to prevent rattling

When to DIY and When to Call a Professional

DIY Repairs

Safe to DIY if:

Frequently Asked Questions

Can I replace the electric gate motor without replacing the Colorbond panels?
Yes, motors and gate structures are separate components. You can upgrade your motor system without altering your Colorbond panels.

Is it safe to manually force open an electric gate?
No. Always use the emergency manual release key. Forcing the gate open can strip gears or damage the motor.

How long should a Colorbond electric gate last?
With proper care, a Colorbond gate frame can last 15–25 years. The electric motor typically lasts 7–12 years, depending on usage and maintenance.

Do solar-powered Colorbond gates need repairs less often?
They require fewer electrical repairs due to lower voltage systems, but the solar panels and batteries need monitoring and replacement every few years.
