Garage Door Repair in Dover: What to Do When It Won't Open
2026-06-02 7 min read
Most people don't think about their garage door until it stops working. Then panic sets in. You're late for work. The car is trapped. Or worse, the door is stuck halfway open, and you're worried about security. The good news: most garage door repair issues in Dover have straightforward causes, and many are fixable faster than you'd expect.
Common Reasons Your Garage Door Won't Open
A stuck or broken garage door usually points to one of a few culprits. Springs are the most common. Garage door springs last roughly 7 to 9 years under normal use, and when they snap, the door becomes impossible to lift by hand. You'll often hear a loud bang in the garage when this happens. Don't try to force the door open yourself.
The second major issue involves the opener itself. If the garage door opener is running but the door isn't moving, the chain or belt inside has likely slipped or broken. Photo eye sensors (those small devices on either side of the door, near the floor) can also malfunction. When they're misaligned or dirty, they trigger the safety reversal feature, and the door won't close.
Cables can fray or snap too, especially if they've been under strain for years. The door tracks may be bent or blocked. Sometimes it's simpler: a blown circuit breaker, a dead remote battery, or a wall switch that's stopped working. Weather, age, and lack of maintenance all speed up these failures.
Troubleshoot Before You Call
Start with the basics. Check your remote batteries first. Try the wall-mounted button in your garage. If that works and the remote doesn't, swap the batteries. Look at the photo eye sensors near the bottom of the door frame. Wipe them with a soft, clean cloth. Dirt and cobwebs block the infrared beam and trigger false safety stops.
Walk around the door and look at the tracks. Is there debris, ice, or a bent section? Clear any obstructions. Listen to the opener when you try to open the door. Does it run but the door doesn't move? That's usually a belt or chain issue. Does it not run at all? Check the circuit breaker in your electrical panel. A tripped breaker is a quick fix.
If none of these steps work, stop. Don't keep forcing the opener or trying to manually pry the door up. You risk injuring yourself or causing more damage.

When to Call a Professional
Spring replacement is never a DIY task. Springs are under extreme tension and can cause serious injury if they snap while you're working on them. The same goes for cable repairs. If your door won't open and you suspect a spring or cable issue, contact a professional immediately.
Opener repairs, track straightening, and sensor realignment are also best left to trained technicians. We've seen plenty of homeowners spend hours trying to fix these problems, only to cause additional damage that makes the final repair bill larger. Our team at Garage Door Dover has the tools and experience to diagnose the problem correctly and fix it right the first time.

Frequently Asked Questions
Q: Can I open my garage door manually if the power is out? A: Most modern openers have a manual release handle. Pull it down to disconnect the door from the opener, then lift the door by hand. It will be heavy if the springs are broken. Never attempt this if springs are snapped.
Q: How long does a typical garage door repair take? A: Simple fixes like sensor cleaning or remote battery replacement take 15 to 30 minutes. Spring replacement usually takes 1 to 2 hours. We aim for same-day service whenever possible in Dover.
Q: Is it safe to use my garage door if it's making loud noises? A: Noise often signals a problem. Grinding sounds suggest track issues. Squeaking means lubrication is needed. Banging may indicate a spring failure. Have it inspected before continued use to avoid safety risks.
Q: What's the difference between a garage door that won't open and one that won't close? A: Won't open usually means a spring, cable, or opener issue. Won't close typically points to photo eye misalignment or a safety sensor problem. Both require professional diagnosis.
Q: How often should I have my garage door serviced? A: Annual maintenance is ideal. A spring inspection, track cleaning, lubrication, and sensor check catch wear before it becomes a breakdown. Regular service extends the life of your system by years.
