Why Is My Garage Door Not Working?
Garage door problems in DFW homes are extremely common and range from simple fixes to safety hazards. The most frequent causes are broken torsion springs which bear the full weight of the door, worn out rollers causing the door to bind in the track, a misaligned track from impact or settling, a failing garage door opener motor or circuit board, snapped cables that run alongside the springs, and sensor misalignment causing the door to reverse before closing. Most garage door issues are mechanical and require a technician rather than a general contractor.
How Serious Is the Problem?
Low
Door opens slowly, makes grinding noise, or remote needs reprogramming. Likely a lubrication or sensor issue. Check sensors and lubricate tracks before calling anyone.
Medium
Door reverses before closing, opens unevenly, or opener runs but door does not move. Likely a sensor, cable, or opener issue. Call a garage door technician within a few days.
High
Loud bang followed by door not opening, door is visibly off track, or cables are visibly snapped. Likely a broken spring — do not attempt to operate the door. Call a technician same day.

Torsion spring replacement is one of the most dangerous DIY repairs a homeowner can attempt. Springs are under extreme tension and can cause serious injury if handled incorrectly. Always hire a professional for spring replacement.
What Can You Check Yourself?
Before calling a technician check these items: Make sure the sensors at the bottom of the door tracks are aligned and the indicator lights are solid. Clean the sensor eyes with a dry cloth. Check that nothing is blocking the sensor path. Lubricate the tracks, rollers, and hinges with a garage door specific lubricant spray — never use WD-40 on garage door components. Check that the opener is plugged in and the circuit breaker has not tripped. Reprogram the remote if the door responds to the wall button but not the remote. Do not attempt spring or cable repairs yourself.
What NOT to Do
- •
Do not attempt to replace torsion springs yourself — they are under extreme tension and can cause serious injury or death
- •
Do not force a door open or closed if it feels unusually heavy — this indicates a broken spring
- •
Do not use WD-40 on garage door tracks or rollers — it attracts dirt and makes the problem worse
- •
Do not ignore a door that is off track — continued use will damage the opener and panels
- •
Do not replace only one spring when both are the same age — the second will fail shortly after
When to Call a Garage Door Technician
Call a garage door technician immediately if you hear a loud bang from the garage which usually indicates a broken spring, if the door is visibly off track, or if cables are hanging loose or snapped. For slower issues like grinding noises or sensor problems, call within a few days. Most garage door companies in DFW offer same-day service and repairs typically take under 2 hours.
Real Example: Keller, TX Homeowner
A homeowner in Keller heard a loud bang from their garage early one morning. When they tried to open the door it would not move. They found a video online showing how to replace a torsion spring and attempted the repair themselves. The spring slipped during installation and put a large dent in the hood of their car parked inside. A technician was called and completed the repair in 45 minutes for $220. The car hood repair cost $800. Always hire a professional for spring replacement.
