If your garage door refuses to open, it’s more than just an inconvenience — it can affect your home’s security, convenience, and safety. At Michigan Door, we’ve seen many of these issues, and while some are fixable by homeowners, others require a professional’s touch. Below is a detailed troubleshooting and repair guide to walk you through the most common causes and next steps.
1. Safety First
Before doing anything:
Disconnect power to the garage door opener.
Use the emergency release (usually a red rope hanging from the opener trolley) only when the door is fully closed — if you pull it while the door is open, the door could fall rapidly.
Understand that components like springs and cables are under extreme tension: attempting to adjust or replace them without proper tools and training can be dangerous.
If you see broken springs, frayed cables, or major mis-alignment — stop and call a pro (like us!) rather than risk injury.
2. Quick Checks You Can Do Yourself
Power & Controls
Make sure the opener has power: no tripped circuit breaker, the outlet is plugged in.
Check the wall switch and remote: perhaps the remote battery is dead, or the remote needs to be re-programmed.
- Ensure the “lock” feature on the opener hasn’t been accidentally engaged (some systems have a lock mode that disables remote triggers).
Safety Sensors (“Photo-Eyes”)
Look at the two small sensors on either side of the door, near the floor. Are they aligned? Is there debris in front of them? Are the indicator lights on?
- Clean the lenses if dirty — misalignment or blockage will cause the door opener to refuse to operate.
Manual Operation
Pull the red emergency‐release rope and try lifting the door manually (only if it’s safe to do so). If the door moves freely when disengaged, likely the opener mechanism is the issue.
If the door is very heavy or stuck even manually, likely mechanical parts (springs, cables, tracks) are the culprit.
3. Common Mechanical / Hardware Issues
When the controls and sensors are fine, the problem usually lies with the mechanical components. Here are the big ones:
Broken or Worn Springs
The torsion or extension springs do the heavy lifting, helping raise the door. If one of them is broken, the opener may run but the door won’t move.
- Because springs are under extreme tension, replacements are not a DIY job for most homeowners. Call a professional.
Snapped or Loose Cables
Cables work in tandem with the springs. If a cable is broken or detached, the door may hang crookedly, skip or refuse to open.
Track Misalignment or Obstruction
If the metal tracks are bent, screws are loose, rollers are damaged, or foreign objects have lodged in the track — the opener may run but the door gets stuck.
- Fixing bent tracks often requires loosening fasteners, tapping into alignment, and re‐securing — a job for a technician if the misalignment is severe.
Opener Mechanism Fault
If you hear the motor running but the door doesn’t budge, the gear inside the opener might be stripped or the trolley carriage might have failed.
- Also consider age of the opener: older units may have worn components and may be better replaced rather than continuously repaired.
Next Steps & When to Call Michigan Door
Here’s how to proceed:
If you identify one of the simpler issues (sensor misalignment, dead remote battery, power outage):
Correct the sensor alignment and clean the lenses.
Replace remote/battery.
Check breaker/outlet for power.
Test the door manually with the release—if it moves smoothly, engage the opener again.
If after the above the door still won’t open:
Don’t force it. Continued attempts may strain the opener or damage the door.
Document what you have tried (sensors, remote, manual lift) — this helps our technician diagnose faster.
Contact Michigan Door. We’ll come and inspect the springs/cables/tracks/opener drive system and recommend the safe, cost-effective fix.
Preventive Maintenance Tips
Twice per year (especially before winter in Michigan) lubricate rollers, hinges, and tracks with a silicone or white-lithium lubricant. This helps keep the door moving smoothly and reduces stress on parts.
Observe the door: if it’s making more noise, moving slower, or the opener is working harder — schedule a tune-up.
Replace worn remotes/batteries, keep the track clean of debris, and check that weather-seal strips haven’t shifted and caught in the track.

Final Thoughts
A garage door that won’t open can quickly turn from an annoyance to a major disruption — especially in Michigan’s weather extremes. Many times, the fix is straightforward (sensor beam blocked, remote battery dead, power tripped). But if the door is heavy, stuck, or the opener motor runs without raising the door, the root cause is often mechanical or electrical — and that’s where a professional is essential.
