Most homeowners don't think about their garage door until it stops working. You press the button, nothing happens, and suddenly you're stuck in your driveway. Before you assume the worst, there are a few things you can troubleshoot yourself. This guide walks you through the most common reasons your garage door won't open and what you can safely check.
First, make sure you're using the right remote. Check the batteries. A dead battery is the number one reason a garage door won't respond to your remote. Replace them and try again. If that doesn't work, try the wall button inside your garage. If the wall button works but the remote doesn't, it's a battery or remote issue, not a door problem.
Next, look at the door itself. Is it visibly stuck or blocked? Leaves, ice, or debris can jam the tracks. A car parked too close or a box sitting in the way stops the door cold. Clear the area around the door and try again. Sometimes the fix is that simple.
If the button and remote both fail, the opener might be unplugged or tripped. Walk to your garage and locate the opener unit on the ceiling. Make sure the power cord is plugged in. Look for a red reset button on the motor itself and press it once. This resets the safety sensors that prevent the door from closing on people or objects.
If your opener has a backup battery, it may have failed. We discuss battery backup systems for garage door openers in detail elsewhere, but know that a dead backup battery can leave you stranded.

Modern garage doors have two sensors mounted near the bottom of the tracks on each side. These sensors create an invisible beam. If the beam is broken or blocked, the door won't open as a safety measure. Check that both sensors are clean and aligned. Wipe them gently with a soft cloth. Make sure no spider webs, dust, or debris is blocking the beam.
If one sensor's light is off while the other is on, that sensor may be broken. This is one repair you should not attempt yourself. The sensors are precision instruments that need professional alignment.
This is where many people run into trouble. Garage door springs are under extreme tension. A broken spring prevents the door from opening, and attempting to force it can cause serious injury. If you hear a loud snap or bang from the garage and the door suddenly feels much heavier, a spring has likely broken. Do not try to open it manually.
We've written extensively about how garage door springs fail and when you should repair versus replace them. A professional needs to handle spring replacement. It's not a DIY job.
If none of these troubleshooting steps work, it's time to call someone. A broken door, stuck cable, damaged track, or failed opener motor all require professional hands. Trying to fix these yourself risks injury and can make the damage worse.
When you contact a repair service, have your answers ready: Does the remote work? Does the wall button work? Do you see any visible damage? Did you hear any unusual noises? This information helps the technician come prepared with the right parts. Most quality repair companies in Stratford and the surrounding areas offer same-day service for broken or stuck doors.

Repair costs vary wildly depending on what's broken. A remote battery costs nothing. A new opener motor runs higher. Springs fall somewhere in between. The best way to know the cost is to get a same-day estimate from a local technician. They'll diagnose the problem and quote you an honest price before starting work.
Don't let a stuck garage door sit for weeks. A door that won't open affects your daily routine and can make your home look abandoned. The sooner you address it, the sooner you're back to normal.
The opener has power, but something is preventing the door from moving. Check the sensors first, then inspect springs and cables. If you hear the motor running but the door doesn't budge, a broken spring is likely. Call a professional immediately.
Costs depend on the problem. A sensor reset is free. A broken spring costs more. Remote batteries are inexpensive. A new opener motor is the highest expense. Get a free estimate to know the exact price for your situation.
Yes, most doors have a manual release handle. Pull the red cord hanging from the opener track to disengage it. Then you can lift the door by hand. However, if a spring is broken, the door will be extremely heavy and dangerous to lift.
Simple fixes like sensor alignment or battery replacement take 30 minutes to an hour. Spring replacement takes longer, usually 1 to 2 hours. Complex opener issues may require more time. Your technician can give you an estimate when they arrive.
Spring, cable, and opener repairs carry serious safety risks. Springs can cause severe injury. Unless you have professional training, hire a licensed technician. Simple troubleshooting like checking batteries and clearing debris is safe to do yourself.
