Your garage door won’t open — and you need to leave in 10 minutes. Before you panic or call for help, work through this step-by-step troubleshooting guide. Most causes can be diagnosed in under 5 minutes, and some can be fixed without a service call.
Start Here — 3 Quick Checks Before Anything Else
Before assuming something is broken, check these three things first — they account for about 20% of all service calls:
- Dead remote battery — Try the wall button inside the garage. If that works, your remote just needs a new battery.
- Tripped circuit breaker — Check your panel for a tripped breaker on the garage circuit. Reset it and try again.
- Manual lock / vacation mode — Some openers have a lock mode that disables the remote. Check for a lock button on the wall panel (often lit red when active).
If none of these fix it, keep reading.
Broken Spring — The #1 Reason Garage Doors Won’t Open
If your opener motor runs and strains but the door doesn’t move — or barely moves — you almost certainly have a broken torsion spring. Look above the door when it’s closed. If you see a gap in the coil of the horizontal spring, that’s your answer.
Do not try to force the door open or keep running the opener. Operating a garage door with a broken spring causes severe damage to the opener, cables, and drums. Call a professional immediately.
Photo-Eye Sensor Issues
Every garage door opener made after 1993 has two photo-eye sensors mounted near the floor on each side of the door opening. If they’re misaligned, dirty, or one is blinking, the door won’t close (and sometimes won’t open).
Fix: Wipe the sensor lenses with a dry cloth. Check that both sensors face each other directly — the indicator lights should be solid (not blinking). Gently adjust the sensor brackets if needed.
Track Obstruction or Misalignment
A pebble, leaf, or piece of debris caught in the track can stop the door mid-travel. Visually inspect both tracks from bottom to top. Also look for dents or bent sections — even a small dent can jam the rollers.
Minor debris: Remove it and test the door. Bent track: This requires professional repair — do not try to hammer it back into shape.
Opener Problems — Gears, Limit Switch, Logic Board
Stripped gears: You hear the motor running but a grinding or clicking sound with no movement. The plastic drive gear inside the opener has worn down. This is a repair job — parts cost $20–$40, labor adds another $100–$150.
Limit switch: If the door goes up but reverses immediately, or stops short of fully open, the travel limit setting needs adjustment. Consult your opener manual — most have a physical dial or screw adjustment on the motor housing.
Logic board failure: If nothing works — no lights, no response to remote or wall button — the logic board may have failed, often due to a power surge. Replacement costs $80–$150 in parts plus labor.
Smart Opener Troubleshooting — MyQ App and WiFi Issues
If you have a LiftMaster or Chamberlain opener with MyQ and your app isn’t working:
- Check that your home WiFi is working — the MyQ hub connects to your 2.4GHz network
- Open the MyQ app and check the device status — it may show “offline” if the hub lost connection
- Unplug the MyQ hub for 30 seconds, then plug back in and allow 2 minutes to reconnect
- If the door works from the wall button but not the app, the issue is WiFi/hub related, not mechanical
- For persistent connection issues, remove the device from the app and re-add it
How to Manually Open Your Garage Door
If you need to get your car out right now and can’t fix the issue immediately:
- Locate the red emergency release cord hanging from the opener trolley (center of the ceiling track)
- Pull the cord straight down — this disconnects the door from the opener
- Manually lift the door by hand from the bottom center
- If the door is too heavy to lift, do not force it — a broken spring makes the door extremely heavy and dangerous to lift alone
When You Need a Professional — Not a DIY Fix
Call All Days Garage Doors if you have: a broken spring (gap visible in coil), a snapped cable, a bent or separated track, a door that’s off the rollers, or any situation where the door is stuck and you can’t identify the cause. These repairs require specialized tools and training — attempting them without experience risks injury and costlier damage.
Frequently Asked Questions
Why is my garage door opener running but the door won’t open?
Almost always a broken torsion spring. Don’t force it — call a technician.
How do I manually open my garage door?
Pull the red emergency release cord, then lift manually. Don’t do this if you suspect a broken spring — the door will be dangerously heavy.
What causes a garage door to stop working suddenly?
Broken spring, broken cable, dead battery, or tripped sensor — in that order of likelihood.
How do I reset my garage door opener?
Hold the Learn/Reset button on the motor unit for 6–10 seconds.
Why does my garage door go up but not all the way?
Usually a limit switch setting or track obstruction.
Can I fix a broken spring myself?
No — springs are under extreme tension and dangerous to handle without proper training and tools.
