A garage door that refuses to move while the opener only hums can be frustrating—especially if you rely on it daily in areas like Edinburgh, Fife, Falkirk, Dundee, Perth, Stirling, Livingston, Angus, the Scottish Borders, St Andrews, East and West Lothian, Tayside, Dunfermline, and East Central Scotland.
This issue is more common than many homeowners think, and while the humming sound usually suggests the motor is receiving power, the door itself is stuck for another reason. In this guide, we’ll explain what causes it, when you can try simple fixes yourself, and when to call in a professional for a reliable garage door repair.
Why Is My Garage Door Opener Humming but Not Moving?
When the motor hums but the door doesn’t budge, it usually means the opener is trying to work but another part of the system is preventing movement. Common causes include:
1. Worn or Broken Drive Gear
Inside most garage door openers is a plastic drive gear that engages with the chain or belt. Over time, this gear wears down. When stripped, the motor runs (causing the humming) but the gear fails to turn the mechanism.
2. Door Springs Have Failed
Torsion or extension springs counterbalance the heavy weight of the garage door. If one breaks, the opener struggles to lift the load, often humming without movement. This is particularly common in older doors across Stirling, Dundee, and Fife.
3. Obstruction or Misalignment
Sometimes, debris in the tracks or a misaligned roller prevents the door from moving. The opener still powers up but can’t overcome the resistance.
4. Capacitor Failure
In electric openers, the start capacitor provides the extra push needed for the motor to engage. A faulty capacitor may cause a humming sound with no action.
5. Door Disconnected from Trolley
If the manual release cord has been pulled, the opener will hum while the door stays still because it’s no longer attached to the drive mechanism.
Quick DIY Checks Before Calling a Professional
If your garage door opener is humming, you can try these safe checks:
- Check the Manual Release – Make sure the emergency cord hasn’t been disengaged accidentally.
- Look for Obstructions – Inspect the tracks for stones, rubbish, or bent sections.
- Test the Door Balance – With the opener disconnected, try lifting the door manually. If it feels extremely heavy, the springs may be broken.
- Examine the Gears – If you’re confident with basic tools, look inside the opener casing for worn drive gears.
⚠️ Safety Warning: Garage door springs are under extreme tension. Attempting repairs without the right experience can be dangerous. If you suspect a spring issue, contact a trusted local expert in garage door repair instead of risking injury.
When You Need Professional Help
In many cases, a humming opener is not a quick DIY fix. For homeowners in Edinburgh, Perth, Dunfermline, and the Scottish Borders, calling a local technician ensures the problem is diagnosed properly and resolved before further damage occurs.
Situations where you’ll definitely need a professional include:
- Broken or worn torsion springs.
- Burnt-out motor or faulty capacitor.
- Stripped drive gears needing replacement.
- Doors that are jammed, misaligned, or off-track.

Why You Shouldn’t Ignore the Problem
A humming opener might seem like a minor inconvenience, but forcing it to run repeatedly can cause motor burnout. A simple part replacement today could turn into a full opener replacement tomorrow.
Additionally, if the issue is related to springs, your door is not safe to use manually. In East Lothian, West Lothian, and Tayside, we’ve seen countless cases where delayed repairs led to avoidable damage and higher costs.
