Garage Door Opener: Common Issues & Fixes
The opener runs but the door doesn’t move
Check that the trolley is engaged (there’s usually a release cord that can
accidentally pull it into manual mode).
Inspect the drive belt or chain, if it’s broken or slipping, it will need replacing.
If you’re not confident handling mechanical parts, our team can repair or
replace the drive system for you.
The door reverses unexpectedly
Clean the safety sensors with a soft cloth as dust or cobwebs can block the
beam.
Check the alignment of the sensors; they should face each other directly.
If the problem persists, the sensitivity settings or motor may need adjustment,
our team can fine-tune this safely.
Unusual noises
Lubricate moving parts (rollers, hinges, and chain) with a garage door-safe
lubricant.
Tighten any loose bolts or brackets.
Grinding or squealing often points to worn parts. Book your door in for professional servicing before the damage worsens.
Troubleshooting Common Garage Door Opener Issues
Even the best systems need occasional maintenance.
Here are a few common problems and what you can do:
The door won’t open or close
Check the remote batteries and replace if flat.
Ensure the opener is plugged in and the power source works.
Look for flashing lights on the safety sensors that may signal a blockage or
misalignment.
If none of these resolve it, the motor or circuit board may be faulty. Give us a call and we can help diagnosis and repair it.

Things to Consider Before Installation
Not all garages, or garage doors, are the same.
Before installing an opener, there are a few key factors to think about:
Door Size and Weight
Heavy timber or insulated doors may require a more powerful opener than a
lightweight roller door. Choosing the right motor ensures reliable performance
without straining the system.
Headroom and Space
The available clearance above your door can affect which type of opener will
work best. A professional installer can assess your setup and recommend the
right model.
Power Supply
Access to power near the garage door is essential. In some cases, extra
wiring may be needed to safely connect your new opener.
Noise Levels
If your garage sits beneath a bedroom or living space, noise can be a
concern. Belt drive systems are generally quieter than chain drives,
something worth considering for family homes.
Future-Proofing
With smart openers now available, some homeowners want Wi-Fi
compatibility and app control. Even if you’re not ready to use those features
today, installing an opener that allows for upgrades can be a smart move.
