Why Your Garage Door Opens Then Stops Halfway

Your garage door opens, then stops halfway because a safety system, a worn part, or a balance issue is preventing it from moving safely. This is one of the most common problems we fix during garage door repair in Miami, especially with doors exposed to heat, humidity, and daily use. When a garage door stops halfway, it is a sign that something is wrong. The door is designed to stop upon sensing resistance or danger. I will explain the most common reasons this occurs and why timely garage door repair is important.

How a Garage Door Decides When to Stop

Modern garage doors are built with safety features. The opener constantly checks for resistance as the door moves. If the system feels something is off, it stops the door to prevent damage or injury. This is good for safety, but it also means small issues can shut the door down. Most halfway stops result from balance issues, worn parts, or restricted movement.

Broken or Worn Garage Door Springs

Garage door springs carry most of the door’s weight. When springs wear out or break, the opener struggles to lift the door. Signs spring issues may be the cause:
  • Door stops halfway going up
  • Door feels heavy when lifted by hand
  • Door closes too fast
  • A loud bang heard earlier
Spring issues are among the top reasons homeowners call for garage door repair service. Spring repairs are dangerous and should always be handled by trained professionals.

Garage Door Is Out of Balance

A balanced garage door should stay in place when opened halfway by hand. If it moves on its own, the balance is off. An unbalanced door puts stress on:
  • The opener
  • The cables
  • The rollers
  • The tracks
When the opener senses extra strain, it stops the door mid-way. This is common in older doors or doors with worn springs. Balance checks are a key part of proper garage door repair.

Track Obstructions or Track Damage

Garage door tracks guide the door up and down. If something blocks the track, the door may stop halfway. Common track issues include:
  • Dirt or debris buildup
  • Bent track sections
  • Rust inside the track
  • Loose track bolts
Even small debris can trigger the opener’s safety stop. In humid areas such as Miami, rust and grime accumulate quickly. Routine garage door services often catch track problems early.

Worn or Stuck Garage Door Rollers

Rollers help the door move smoothly. When rollers wear out or seize, the door cannot move freely. Signs of roller problems include:
  • Jerky door movement
  • Loud squeaking or grinding
  • Door shaking as it moves
If the rollers stop rolling, the opener senses resistance and stops the door halfway to protect the system. Roller replacement is a common garage door repair that improves smooth movement.

Garage Door Opener Force Settings Are Off

Garage door openers use force settings to decide how much power is needed to move the door. If these settings are too low:
  • The opener thinks there is resistance
  • The door stops halfway
If settings are too high:
  • The system becomes unsafe
Force settings often change when parts wear out or after power outages. Adjusting them without addressing the root cause can cause further damage.

Garage Door Sensors Are Triggering a Stop

Safety sensors are designed to stop the door if something crosses the opening. Sometimes they trigger when nothing is there. Common sensor issues include:
  • Dirty lenses
  • Misaligned sensors
  • Moisture damage
  • Loose wiring
While sensors typically prevent doors from closing, some systems can also stop movement if errors occur.

Garage Door Cables Are Fraying or Loose

Cables work with the springs to lift the door evenly. If a cable fails, the door may lift unevenly and stop. Warning signs include:
  • Door rising crooked
  • One side higher than the other
  • Slack cable visible
Cable issues are serious and can cause sudden failure.

What To Do When Your Door Stops Halfway

If your garage door stops halfway:
  1. Do not force it
  2. Check for visible obstructions
  3. Listen for unusual sounds
  4. Avoid repeated attempts to open it
Forcing the door can damage the opener or cause injury.

Getting Your Garage Door Working Again

A garage door that opens then stops halfway is telling you something is wrong. Springs, tracks, rollers, sensors, or the opener may be struggling. Early garage door repair prevents bigger problems and keeps your system safe. If your door is stopping halfway, addressing it now can save time, money, and stress while keeping your garage door working as intended.
