Garage Door Won't Open? Troubleshoot Like a Pro in Newmarket

2026-05-17

A stuck garage door that won't open usually points to one of four common culprits: a dead remote battery, a tripped safety sensor, a broken spring, or a jammed track. In our years serving Newmarket, we've seen this problem again and again, and the fix is often simpler than homeowners expect.

Start with the Remote and Power

Before you assume something is broken, test whether the issue lives in your remote or your door itself. Replace the batteries in your remote first. A dead battery is the easiest fix and costs almost nothing.

Next, walk to your garage door opener (the unit mounted on your ceiling) and press the wall button directly. If the door responds to the wall button but not the remote, your remote batteries are the answer. If neither works, the opener itself might have lost power. Check that it's plugged in properly and that your garage outlet has power by testing another device.

Check Your Safety Sensors

Modern garage doors have two infrared sensors positioned low on each side of the opening. These sensors prevent the door from closing if something (or someone) is in the way. When they malfunction, the door won't operate at all.

Look for small LED lights on each sensor. They should glow steadily. If one is dim, flickering, or dark, the sensor may be blocked by dust, cobwebs, or misalignment. Wipe both sensors clean with a soft cloth. If the lights still don't match or the door remains stuck, the sensors may need professional adjustment or replacement.

The Broken Spring Problem

Garage door springs last roughly 7 to 9 years under normal use. When one breaks, the door becomes extremely heavy and won't open, even if your opener is working. A broken spring is not a DIY job.

Springs are under tremendous tension. Attempting to replace or adjust them without proper tools and training can cause serious injury. If you hear a loud bang from your garage (the sound of a spring snapping) or notice the door is suddenly much heavier, stop using it and call for professional service. We can provide a same-day estimate and handle the replacement safely.

Inspect the Tracks and Hardware

Garage door tracks guide the rollers up and down. If debris, rust, or a bent section blocks the track, the door gets stuck. Grab a flashlight and look inside both vertical tracks along the sides of the door. You might spot a bent roller, accumulated dirt, or something wedged inside.

If the obstruction is minor dirt or dust, vacuum or sweep it out. If you see a bent track or a roller that's obviously damaged, that's work for a professional. Straightening tracks requires special tools, and forcing a stuck door can cause more damage and raise your repair cost considerably.

Frequently Asked Questions

Why won't my garage door open even though I hear the opener running? The opener motor may be running, but if the door is still stuck, the problem is likely a broken spring, misaligned track, or jammed roller. The motor can't lift the weight of the door on its own without a functioning spring system.

Can I force my stuck garage door open manually? No. Forcing a stuck door can bend the tracks, damage rollers, or hurt you. If the door is stuck, stop trying to open it and call for professional help to avoid making the problem worse.

How much does garage door repair cost in Newmarket? Repair costs vary widely depending on the problem. A simple sensor adjustment might cost $50 to $100, while a broken spring replacement ranges from $150 to $300 per spring. We provide a free estimate before any work begins.

Should I replace both springs if one is broken? Yes. Springs work in pairs, and when one breaks, the other is usually near the end of its life too. Replacing both at the same time saves you money and prevents the second from failing weeks later.
