How to Fix a Garage Door That Wont Open
New Jersey homeowners: if your garage door refuses to open, use this safe, step-by-step guide to diagnose common issues before calling for service. For professional help, see Garage Door Repair in NJ or 24/7 Emergency Repair.
Quick Answer (TL;DR)
If your garage door won’t open at all, check power and wall control lock, try the wall button, clean and realign photo sensors, switch to manual mode (red release cord), and visually inspect springs or cables without touching them.
- Opener clicks, no movement: likely a broken spring or disconnected trolley — see Spring Replacement and Opener Repair.
- Cold weather in NJ: frozen bottom seal and thick lubricants are common—clear ice and use a low-temperature lithium/silicone lubricant; consider a seasonal Tune-Up & Maintenance.
- See damaged springs/cables? Stop and call a technician. We handle Cable Repair and Springs.
When It’s Safe to DIY — and When to Stop
DIY-safe: power checks, remote/keypad programming, photo-sensor alignment, track cleaning, minor travel/force tweaks, wall-panel lock, temporary manual mode.
Call a pro: broken/stretched springs, snapped cables, bent tracks, heavy doors, gear/drive repairs. These parts carry high tension and can be dangerous — Contact us.
Tools You May Need
Flathead screwdriver, adjustable wrench, microfiber cloth, level, zip ties, alcohol wipes for sensors, and lithium or silicone-based lubricant rated for low temperatures.
Step-by-Step Troubleshooting
1) Check Power and Lock
- Verify the opener is plugged in and the outlet works (test another device).
- Check the breaker or GFCI.
- On the wall control, ensure Lock mode is off—Lock disables remotes.
2) Test Remote, Keypad, and Wall Button
- Replace the remote battery and test within a few feet of the door.
- If the wall button works but the remote doesn’t, reprogram the remote/keypad (LiftMaster/Chamberlain/Genie steps vary) — more in Opener Repair.
- Check the keypad for moisture.
3) Inspect and Align Safety Sensors
- Photo-eyes must face each other with a steady indicator light.
- Wipe lenses clean and adjust until both lights are solid.
- Inspect wires for damage or loose connections. Need help? Sensor Repair.
4) Adjust Travel and Force Limits
- If the door starts then stops/reverses, turn Travel/Force screws 1/8–1/4 turn toward “+” and test.
- Minor seasonal tweaks are normal in NJ’s freeze-thaw climate. Persistent issues ⇒ Opener diagnostics & repair.
5) Try Manual Release and Balance Test
- Pull the red emergency cord to disengage the trolley.
- Lift the door halfway:
- Balanced: stays in place — springs are okay.
- Drops/heavy: spring issue — stop and book Spring Replacement or Cable Repair.
- If it moves smoothly by hand but not with the opener, check the opener/carriage — Opener Repair NJ.
6) Visual Check: Springs, Cables, Rollers
- Springs: visible gap/crack in the coil — replace torsion/extension springs.
- Cables: frayed or off the drum — garage door cable repair.
- Rollers: cracked, flattened, or noisy — roller replacement.
7) Tracks and Obstructions
- Clear debris, tools, or ice along the tracks.
- Tighten loose brackets gently; don’t bend rails aggressively.
- Do not lubricate tracks—keep them clean and dry. For a full check-up, book a Tune-Up.
8) Cold-Weather Checklist for NJ
- Frozen bottom seal: break ice gently and apply silicone spray to the rubber seal.
- Use winter-grade lubricant for rollers and hinges.
- Keep the threshold clear of slush/water.
- Add small shades if low winter sun triggers sensors. Consider seasonal maintenance.

Local Tips for New Jersey Homeowners
- Freeze–thaw cycles affect travel/force—small seasonal adjustments are normal.
- Road salt speeds corrosion—rinse hardware, then re-lubricate monthly in winter. Consider a maintenance visit.
- Storm season: consider battery backup to keep the opener working during outages — ask about Opener Installation.
- Humidity control: dehumidify attached garages to protect sensors and boards.
When to Call a Professional

FAQ
Why won’t my garage door open but the motor clicks?
A broken torsion or extension spring—or a disengaged trolley—is common. Do not try to lift the door; call a technician. See Spring Replacement.
Why won’t my garage door open in cold weather?
Cold can freeze the bottom seal and increase friction. Clear ice, use low-temperature lubricant, and check travel/force settings. A seasonal Tune-Up can prevent repeats.
Should I lubricate the tracks?
No. Keep tracks clean and dry. Lubricate hinges and rollers only with lithium or silicone grease. For noisy rollers, book roller replacement.
How do I know if a spring is broken?
Look for a visible gap in the torsion spring, a heavy door in manual mode, or a motor that runs without moving the door. Get professional replacement.
Do I need to reprogram my remote?
If the wall button works but the remote doesn’t, replace the battery, disable Lock mode, and reprogram it per your opener’s manual. Persistent issues? Opener Repair.
