How to Tell if It's the Garage Door Spring or the Opener That Failed
Table of Contents
You press your garage remote. The motor hums, but nothing happens. The door may move a few inches and stop.
Or you hear a loud bang from the garage door, and now the door won’t budge. When your garage door won’t open, it’s natural to wonder: is it the spring or the opener that failed?
At Ottawa Garage Doors & Openers, we get this call every day from homeowners across Ottawa, Kanata, Barrhaven, Orleans, and Stittsville.
Both garage door springs and openers are essential to proper operation, and both can fail suddenly. Understanding the difference helps you spot the warning signs and avoid costly or dangerous mistakes.
In this guide, you’ll learn how to tell whether you need garage door spring replacement or garage door opener repair, plus what you can safely check yourself before calling a technician.
The Role of Garage Door Springs and Openers
Your garage door system consists of two primary power sources: springs and the opener.
- Springs (torsion or extension) handle the heavy lifting. They counterbalance the door’s weight, making it possible for even a small motor—or your hand—to raise a door weighing over 150 pounds with ease.
- The opener, on the other hand, automates the process. It guides and controls movement, but it doesn’t do most of the lifting.
Think of it like this: the springs do the muscle work, and the opener is the brain that tells them when to move. When one fails, the other can’t function properly.
Common Signs of a Broken Garage Door Spring
A broken garage door spring is one of the most common causes of a garage door not lifting or staying shut. Springs are under extreme tension, so when one breaks, it’s noticeable. Here’s what to look for:
- The door feels heavy or won’t lift manually.
- You hear a loud bang from the garage, often mistaken for something falling to the ground.
- There’s a visible gap in the torsion spring (the coil above your door).
- Garage door cables appear loose or hanging.
- The opener tries to lift but stops or strains without success.
If your garage door opener runs but the door doesn’t move, a spring has likely snapped.
Safety Tip: Never attempt to repair or tighten springs yourself. They can cause serious injury if mishandled.
If you notice any of these signs, don’t force the door; call Ottawa Garage Doors & Openers for same-day garage door repair in Ottawa.
We carry all major spring types and sizes to get your door working again safely and fast.
Common Signs of a Faulty Garage Door Opener
Sometimes the springs are fine, but the opener itself is having trouble operating. Here’s how to spot a bad opener motor or drive system:
- The motor runs, but the door doesn’t open. (This means the internal gears or trolley could be stripped.)
- Opener lights blink, but nothing happens.
- The remote or wall switch becomes unresponsive.
- You hear grinding, clicking, or buzzing from the opener housing.
- The door moves a few inches and stops, even though the springs are intact.
Before assuming total failure, do a few quick checks:
- Ensure the power outlet and circuit breaker are functioning correctly.
- Check the remote batteries.
- Ensure the safety sensors near the floor are aligned and not blocked.
If everything checks out, but your garage door opener still won’t lift, it’s time for professional repair of the opener.
Quick At-Home Tests (Safe Checks Only)
You can safely do a couple of simple tests to help narrow down the cause without touching any high-tension parts.
1. Unplug the opener and try to lift the door manually.
- If the door is hefty or won’t move, it’s likely a spring issue.
- If it lifts easily, the problem may be with the opener or sensors.
2. Listen for sounds.
- A loud bang or a hanging cable indicates a torsion spring failure.
- A clicking opener motor often means an internal gear issue.
3. Never attempt to tighten or replace a spring yourself; leave this task to trained technicians.
When to Call a Professional
A malfunctioning garage door isn’t just inconvenient; it can be dangerous. Misdiagnosing the issue can also lead to wasted money or damaged parts.

Preventive Maintenance Tips
Preventing sudden failures starts with regular maintenance. A few minutes of care can add years to your system’s life:
- Lubricate springs, rollers, and hinges every few months.
- Check the balance of your door annually—an unbalanced door stresses both the opener and springs.
- Replace both springs if one breaks to maintain proper tension.
- Inspect cables and tracks for fraying or rust.
- Test the opener’s safety reverse feature to ensure it responds correctly.
