Garage Door Won't Open in Longmont? Here's How to Troubleshoot

2026-05-16 7 min read

If your garage door won't open, you're not alone. After 15 years on the job in Longmont, I've rolled up to hundreds of homes with the exact same problem. The good news is that most stuck or broken garage doors have a simple fix. Sometimes it's not even a repair. Let me walk you through what to check before you call us out.

Check the Power and Remote First

Start with the basics. Is your garage door opener plugged in? Sounds silly, but I can't tell you how many service calls turn out to be a tripped breaker or a cord that got unplugged during cleaning. Look at the outlet where your opener is mounted. If you have a plug-in model, make sure it's seated all the way in. See our guide on does your longmont garage door actually need insulation? an honest answer.

Next, test your remote. Replace the batteries. A dead remote battery is one of the most common reasons a door won't respond to commands. Try the wall button inside your garage while standing close to the opener. If the wall button works but the remote doesn't, it's the batteries or the remote itself, not your door.

If neither the remote nor the wall button works, the problem is likely with your opener or the electrical connection. This is when you should schedule a free quote with our team to get it diagnosed properly. Read about garage door safety in longmont: what every homeowner needs to know.

Look for Obstructions and Safety Sensors

Modern openers have safety sensors on both sides of the door opening, usually about 6 inches from the ground. These sensors detect objects and prevent the door from closing on anything in its path. If they're misaligned, dirty, or blocked, your opener may refuse to work as a safety feature.

Walk around the door opening. Remove any leaves, trash, or debris that might be blocking the sensor beam. Look at the sensor lenses. If they're dusty or spattered with mud, wipe them clean with a soft cloth. Even a little grime can interrupt the signal.

Also check for anything physical blocking the door's path. Boxes, cars parked too close, or even snow buildup in winter can prevent smooth operation. I've troubleshot plenty of "broken" doors in Boulder and Longmont that just needed a clear track.

Inspect the Springs and Track

This is where you need to be careful. Garage door springs are under extreme tension, and I don't recommend touching them yourself. That said, you can look for obvious problems. If your door is sagging or won't move at all, a broken spring is likely the culprit. Springs last 7 to 9 years depending on use, not 10. We cover replacement and diagnosis in our guide to spring replacement signs.

Check the track on both sides of the door. Look for dents, bent sections, or metal debris. If the track is bent, the rollers can't move smoothly. A bent track usually requires professional repair or replacement.

If the door is stuck but not broken, try gently pulling the emergency release cord on your opener. This disconnects the door from the motor so you can manually move it a few inches. If it budges easily, the problem is the opener or sensors. If it's still stuck solid, suspect the springs or track.

Test Your Opener's Force Settings

Some openers have adjustable force settings that can get accidentally changed. If the door starts to move but stops partway, the force setting might be too low. Check your opener's manual for instructions on adjusting this. Again, if you're not comfortable doing this, our technicians can handle it in minutes.
