Step-by-Step Troubleshooting Guide

Check the Power Source:
Is the opener plugged in and getting power? Check for tripped breakers or blown fuses.

Test the Remote Batteries:
Replace the batteries in your remote—even new ones can be faulty.

Inspect the Safety Sensors:
Dirty or misaligned sensors can stop the door from closing. Clean and realign them.

Look for Obstructions:
Make sure nothing is blocking the door’s path or the sensors.

Reset the Opener:
Most openers have a reset button—try resetting and reprogramming the remote.

Listen for Unusual Noises:
Grinding or clicking sounds may signal worn gears or a failing motor.

A client in St Ives avoided a major breakdown by calling us after hearing a strange clicking noise—our tech replaced the gear assembly before the opener failed.

Preventative Maintenance: Keep Your Opener Reliable

• Test your opener monthly for smooth, quiet operation
• Lubricate moving parts every 3–6 months
• Check and replace remote batteries regularly
• Clean safety sensors and tracks
• Book a professional tune-up annually, especially if you live near the coast.
