Quick Answer: What to Do Right Now
✓ Try these safe checks first:
- Check if the opener is plugged in and has power
- Replace the remote control batteries
- Look for obstructions blocking the door or sensors
- Try the wall button — if it works, the issue is the remote
- Check if the manual release cord has been pulled
⚠ Call a professional immediately if:
- The door feels extremely heavy when you try to lift it manually
- You heard a loud bang from the garage (likely a broken spring)
- The door is visibly off-track or crooked
- The opener motor runs but the door doesn't move
- Cables are hanging loose or appear frayed
Why Won't Your Garage Door Open?
| Symptom | Likely Cause | Safe DIY Check | Call a Tech If... |
|---|---|---|---|
| Door won't move at all | Broken spring or disconnected opener | Try lifting manually — if very heavy, spring is broken | Door is too heavy to lift by hand |
| Motor hums but door doesn't move | Stripped gear, broken belt/chain, or jammed track | Disconnect opener and try manual operation | Door still won't move manually |
| Remote doesn't work but wall button does | Dead battery or deprogrammed remote | Replace batteries and reprogram remote | New batteries don't fix it |
| Door opens a few inches then stops | Broken spring or travel limit issue | Check for obstructions near the bottom | No obstruction found — likely spring failure |
| Door is crooked or jammed | Off-track, broken cable, or roller failure | Do not force the door — visual inspection only | Any visible damage or misalignment |
| Opener light flashes but doesn't run | Safety sensor misalignment or lock mode | Clean and realign the sensor eyes | Sensors are aligned but issue persists |

When to Call a Professional
While some garage door issues have simple fixes, many require professional tools and expertise. Broken springs, snapped cables, and off-track doors are dangerous to repair without proper training and equipment. Our licensed Sydney technicians carry parts for the most common failures and can usually complete the repair in a single visit.
If your garage door won't open and you've ruled out the simple checks above, don't delay — a malfunctioning door is both a security vulnerability and a safety hazard, especially if you have children or pets. See our full guide to common garage door problems for more troubleshooting tips.
