Your garage door stopping halfway up is frustrating and potentially dangerous, leaving your home exposed and your routine disrupted. This issue typically signals a safety mechanism activation or mechanical problem that needs immediate attention to restore normal operation.
Step-by-Step Fixes
Step 1: Check the Safety Sensors
Look at the bottom of your garage door tracks near the floor. You’ll see two small sensors with LED lights facing each other. Wipe both sensor lenses with a soft cloth to remove dirt, spider webs, or debris. Make sure nothing blocks the invisible beam between them – even a leaf can trigger the safety stop. The sensors should have steady lights (usually green and red). If one blinks, gently adjust its position until both lights stay solid.
Step 2: Test the Manual Release
Pull the red emergency cord hanging from your garage door opener rail. This disconnects the door from the motor. Now lift the door manually. It should move smoothly without excessive force. If it feels heavy or stuck at the halfway point, you’ve found a mechanical issue. If it moves freely, reconnect it by pulling the cord toward the motor until you hear a click.
Step 3: Adjust the Travel Limits
Find the limit adjustment screws on your garage door opener motor unit – they’re usually labeled “up” and “down” with arrows. Using a flathead screwdriver, turn the “up” limit screw clockwise a quarter turn. Test the door. If it still stops halfway, continue adjusting in small increments. Most Chamberlain, LiftMaster, and Genie models from 2020-2025 have these screws on the left side of the motor housing.
Step 4: Reset the Force Settings
Locate the force adjustment dials near the limit screws. These control how much power the motor uses. Turn the “up force” dial slightly clockwise to increase power. Test the door after each small adjustment. Modern smart openers like MyQ-enabled models often have force settings in their smartphone apps instead of physical dials.
Step 5: Clear the Tracks
Inspect both vertical tracks from floor to ceiling. Look for dents, bends, or objects stuck in the track groove. Use a level to check if tracks are plumb (perfectly vertical). Spray silicone lubricant on the rollers and hinges – avoid WD-40 as it attracts dirt. Wipe excess lubricant to prevent drips on your car.
Step 6: Check Spring Tension
Look at the torsion spring above your garage door (the large coiled spring on a metal shaft). If you see gaps between the coils or the spring appears stretched, it’s losing tension. This is ideal for professional service as spring adjustment is dangerous without proper tools and training.
Likely Causes
Cause #1: Obstruction Detection Activation
Your garage door opener thinks something is in the way. This safety feature, mandatory since 1993, prevents the door from crushing objects or people. The system uses infrared sensors to create an invisible tripwire across your garage opening.
Check for it by looking for blinking lights on your sensors or opener unit. Walk through the sensor beam area and remove any items. Even direct sunlight hitting a sensor can trigger false obstruction alerts, especially during sunrise or sunset. Consider installing sensor shields if sunlight is your issue.
Cause #2: Worn or Broken Springs
Garage door springs counterbalance the door’s weight, typically 150-400 pounds depending on door size and material. Springs have a lifespan of 10,000-20,000 cycles, meaning they last 7-14 years with average use. When springs weaken, your opener motor struggles to lift the door’s full weight.
Test spring condition by disconnecting the opener and manually lifting the door to waist height. A properly balanced door should stay in place. If it drops or feels extremely heavy, your springs need attention. Never attempt spring replacement yourself – the stored tension can cause severe injury.
Cause #3: Travel Limit Misconfiguration
Your opener’s computer doesn’t know where “fully open” is anymore. This happens after power outages, when someone bumps the motor unit, or simply from vibration over time. The opener thinks halfway up is the fully open position.
Identify this issue when your door stops at exactly the same spot every time without any grinding or struggling sounds. The motor simply stops as if it completed its job. This is the easiest fix and ideal for DIY resolution using the adjustment steps above.
When to Call Expert Help
Contact a garage door technician immediately if you notice broken cables, hear loud banging when the door moves, or see the spring is clearly broken (gap in the coils). These situations are not recommended for DIY repair due to serious injury risk.
Professional help is best when basic troubleshooting doesn’t work within 30 minutes, or if your door is over 10 years old and showing multiple issues. A technician can diagnose complex problems like circuit board failures or worn gear assemblies that aren’t visible during basic inspection.

“My garage door opens halfway then stops going up. It’s a [insert brand] opener installed in [year]. I’ve checked the sensors and they have solid lights. The door moves freely when disconnected from the opener. No visible obstructions in tracks. What specific troubleshooting steps should I try for my model? Include safety warnings.”
Remember, a garage door that stops halfway isn’t just inconvenient – it’s a security risk. Address this issue promptly to protect your home and family. Most halfway-stopping problems are fixable within an hour using these steps, restoring your door to smooth, reliable operation.
