A garage door that won’t stay open is a common and inconvenient issue. The door may shut unexpectedly, reverse after opening, or fail to remain in position. Below are the typical reasons this happens and practical steps to fix it.
Common Causes of a Garage Door Not Staying Open
- Incorrect or Weak Springs
Garage door springs are essential to balance the door’s weight. Worn, broken, or improperly adjusted springs can’t hold the door up, causing it to fall shut. - New Extension Springs Not Properly Settled or Sized
If new extension springs are too weak or the wrong size, the door won’t stay open. Springs also need a break-in period to adjust tension. - Damaged or Loose Cables
Cables work with springs to balance the door. Frayed, stretched, or loose cables prevent the door from staying in position. - Misaligned or Dirty Safety Sensors
Sensors prevent the door from closing if an obstacle is detected. If misaligned or dirty, they may cause the door to behave erratically. - Incorrect Opener Travel Limit Settings
Travel limits tell the opener how far to open or close the door. Incorrect settings can cause premature closing or failure to hold open. - Track Problems or Obstructions
Bent, dirty, or obstructed tracks increase friction and can prevent the door from staying open. - Opener or Motor Malfunctions
A faulty opener motor or control board may cause inconsistent door operation.
How to Fix a Garage Door That Won’t Stay Open
- Inspect and Adjust Springs and Cables
Check for proper tension, wear, and damage. Professional repair or replacement is often needed. - Clean and Align Sensors
Wipe sensor lenses and ensure they face each other properly. - Reset Opener Travel Limits
Follow the opener’s manual to adjust how far the door travels to open or close. - Clear and Lubricate Tracks
Remove debris and apply appropriate lubricant on tracks and rollers. - Check Controls and Replace Batteries
Weak remote or wall button batteries can impair operation. - Seek Professional Help If Needed
Motor or system malfunctions require expert diagnosis.
When to Call a Professional
If adjustments and basic maintenance don’t fix the problem, contact a qualified garage door technician. Springs and cables are under high tension and repairs should be done safely.
FAQ About Garage Doors Not Staying Open
Why do my new springs not keep the door open?
New springs might be wrong size or need time to settle. Check specifications and allow a break-in period.
Can misaligned sensors cause the door to close?
Yes. Dirty or misaligned sensors trick the system into believing there is an obstruction.
Is it dangerous to fix springs myself?
Yes. Springs are under great tension and can cause serious injury. Professional service is recommended.
How often should springs be replaced?
Typically after 7-10 years or about 10,000 cycles, but heavy usage or weather can shorten lifespan.
Keeping the garage door operating safely and smoothly depends on spring health, sensor alignment, opener settings, and clear tracks. Regular maintenance and timely repairs prevent most problems with the door not staying open.
