How To Fix a Garage Door That Won't Open All The Way
You must agree, few things are more frustrating than pressing your garage door opener and watching the door rise only to stop halfway.
A garage door that won’t open all the way can throw off your entire routine, trap your vehicle inside, or signal a deeper issue that you shouldn’t ignore.
In many cases, the problem starts suddenly, even though the door seemed to work fine the day before.
The good news is that this issue is common, and many causes are easy to identify once you know what to look for.
From sensor problems to spring tension issues, understanding why your garage door won’t open can help you decide whether a quick fix is possible or if it’s time to call a professional.

Why Garage Doors Stop Before Fully Opening
Your garage door relies on a balance between the opener and the door’s lifting system. The opener guides movement, but the springs do most of the heavy lifting.
When components struggle, the system reacts by stopping the door mid-cycle to prevent damage or injury.
A garage door that won’t open fully is often a safety feature. Modern openers are designed to stop when they sense resistance, imbalance, or an obstruction. While it’s a good thing, it also means minor issues can cause significant disruptions.
Common Reasons a Garage Door Won't Open All The Way (And How to Fix Them)
1. Spring Tension or Balance Problems
If your garage door won’t open, worn or weakened springs are often the common cause. The springs counterbalance the door’s weight, allowing the opener to lift it smoothly.
How to check:
- Disconnect the opener and lift the door manually
- If the door feels heavy or won’t stay open halfway, the springs may be failing
Spring repairs are not DIY-friendly. High torsion makes them dangerous for you to handle alone, so professional service is recommended.
2. Track or Roller Issues
Bent tracks, dirt buildup, or worn rollers can cause the door to bind during operation. Even a small obstruction can trigger the opener to stop.
What to look for:
- Visible dents or gaps in the tracks
- Debris or hardened grease
- Rollers that stick or wobble
Cleaning the tracks and lubricating the rollers may help, but if they’re severely damaged, professional realignment and replacement are required.
3. Safety Sensor Problems
If your garage door won’t open all the way but closes fine, safety sensors could be the problem. These sensors help to stop the door movement if they detect an obstruction, even if none is present.
Quick checks:
- Clean the sensor lenses
- Make sure both sensors are aligned and facing each other
- Remove anything blocking the beam
Misaligned sensors are one of the easiest fixes and often restore your door to full operation.
4. Opener Force or Limit Settings
Sometimes the problem isn’t mechanical at all. Opener force and travel limit settings tell the motor how far and how hard to lift the door.
If these are off, the opener may think the door has reached its maximum height when it hasn’t.
Signs this may be the issue:
- The door stops at the same height every time
- No grinding or jerking motion
Adjustments should be made carefully and in accordance with the manufacturer’s instructions to avoid safety risks.
5. Power, Remote, or Control Issues
Before assuming a major repair is needed, check the basics. Weak remote batteries, power interruptions, or control board glitches can mimic mechanical problems.
Try this first:
- Replace the remote batteries
- Use the wall control instead of the remote
- Reset the opener if recommended by the manufacturer
A simple reset resolves the issues.
6. Worn or Broken Hardware
Cables, pulleys, and internal opener gears wear down over time. When these components fail, the door may start lifting but lack the support needed to reach full height.
Warning signs include:
- Grinding or clicking noises
- Uneven lifting
- Frayed cables
A trained technician should always do these repairs.
DIY Troubleshooting Checklist
If you want to narrow down the issues, we recommend you follow this order:
- Check the power and remote batteries
- Inspect and clean safety sensors
- Look for track obstructions or damage
- Test the door balance manually
- Review the opener limit and force settings
- Visually inspect springs and cables
If anything looks damaged or unsafe, contact Ottawa Garage Doors & Openers to help check the problem and fix it.
DIY Fixes vs. Professional Garage Door Repair
Some problems, such as sensor alignment or lubrication, are safe for you to handle. Others, especially involving springs, cables, or door alignment, can cause serious injury if mishandled.
If your garage door won’t open after basic checks, professional garage door repair ensures the issue is fixed the first time correctly.
Preventing This Problem in The Future
Regular maintenance goes a long way in preventing partial door openings. Simple steps include:
- Annual lubrication of moving parts
- Periodic balance testing
- Tightening loose hardware
- Visual inspections for wear
With routine service, it helps extend the life of your door and opener while preventing inconvenient breakdowns.
Frequently Asked Questions
Why does my garage door stop halfway?
Resistance, balance issues, or sensor interference are the most common reasons why your door stops halfway.
Can I keep using the door if it only opens partway?
No, continued use can strain the opener and worsen the problem.
Is it dangerous to adjust springs myself?
Yes, garage door springs are under extreme tension and should only be handled by professionals.
Why does the problem happen only sometimes?
Temperature changes, intermittent sensor alignment, or failing components can cause inconsistent behaviour.
Will a new opener fix the issue?
Only if the opener is the source of the problem, many issues are mechanical, not electrical.
