Introduction
If your garage door goes up but not down with opener, it can be frustrating and potentially unsafe. Many homeowners face this problem due to safety sensors, misaligned tracks, or mechanical issues. In this guide, we’ll explore the common causes, troubleshooting tips, and step-by-step solutions to restore smooth garage door operation.
Common Causes Why Garage Door Won’t Go Down
Several factors can prevent a garage door from closing while still opening properly:
- Safety Sensors Misalignment: Modern doors have infrared sensors near the floor. If blocked or misaligned, the door won’t close.
- Obstructed Tracks or Rollers: Dirt, debris, or bent tracks can stop the door from lowering.
- Worn or Broken Springs: Torsion or extension spring issues can affect downward movement.
- Faulty Garage Door Opener: Malfunctioning circuits or limit settings can prevent closing.
- Remote or Wall Switch Problems: Malfunctioning buttons can trigger only upward motion.

Step-by-Step Guide to Fix a Garage Door That Opens But Doesn’t Close
Step 1: Ensure Safety First
- Disconnect the garage door opener from power.
- Avoid standing under the door while testing.
- Wear gloves and safety glasses.
⚠️ Important: Garage doors are heavy and springs are under tension. If unsure, call a professional.
Step 2: Check Safety Sensors
- Locate the infrared sensors near the floor on each side of the door.
- Clean lenses with a soft cloth to remove dust or dirt.
- Ensure the sensors are aligned: the indicator lights should be steady, not blinking.
- Remove any obstacles in the path of the door.
Step 3: Inspect Tracks and Rollers
- Look for bent tracks or worn rollers.
- Clear debris or small objects that might block movement.
- Lubricate rollers and hinges with garage door lubricant.
Step 4: Check Springs and Cables
- Inspect torsion or extension springs for wear, gaps, or breakage.
- Ensure cables are intact and properly attached.
- If springs are broken or loose, call a professional—springs store dangerous tension.
Step 5: Test the Garage Door Opener
- Check limit switch settings on the opener: the “down” limit may need adjustment.
- Reset the opener if needed: unplug, wait 30 seconds, and plug back in.
- Test both wall button and remote.
