Garage Door Won’t Open? 8 Causes and What to Do
Quick safe checks first, then when to call for help. Car trapped? Call 24/7.
A garage door that will not open is frustrating, especially on a cold Hamilton morning when you need to leave. Most causes fall into a few groups: power, remote, ice, springs or cables. Some are quick to fix yourself; others need a professional.
If your garage door won’t open, check power to the opener, remote batteries and the lock button, and look for ice freezing the bottom seal. Then look for a broken spring (a gap in the coil above the door) or loose cables. If the opener hums but the door does not move, or a spring is broken, stop and call (513) 286-7477.
8 Common Causes
| Cause | Sign | DIY or pro? |
|---|---|---|
| No power | Opener lights off | DIY: check GFCI and breaker |
| Dead remote | Wall button works, remote does not | DIY: new batteries |
| Lock button on | Remotes stop working | DIY: turn off lock |
| Frozen bottom seal | Opener strains on a cold morning | DIY: gently free the seal |
| Broken spring | Loud bang, gap in coil, door heavy | Pro |
| Snapped cable | Door crooked or one side low | Pro |
| Stripped opener gear | Motor hums, door stays put | Pro |
| Off-track door | Rollers out of track | Pro |
In winter, see garage door frozen shut.
Safe Checks You Can Do
- Check the GFCI outlet and garage breaker.
- Replace the remote batteries.
- Make sure the lock button is off.
- Check for ice along the bottom seal.
- Look for a gap in the spring above the door (do not touch it).
⚠️ Safety warning: If a spring or cable is broken, do not pull the red release cord and try to lift the door. It can be extremely heavy and fall.

Frequently Asked Questions
Why won’t my garage door open in cold weather?
Ice may be freezing the bottom seal to the ground, grease may be stiff, or a spring may have broken in the cold. Check for ice and for a gap in the spring.
How do I open my garage door manually?
If the springs are intact and the door is closed, pull the red release cord and lift by hand. If it is very heavy, stop; a spring is likely broken.
Can a broken spring stop the door from opening?
Yes. Springs lift the door, not the opener. With a broken spring most openers cannot lift it.
