Garage Door Repair Troubleshooting in Candia: Fix It Before You Call
2026-07-28 7 min read
After 15 years on the trucks, I can tell you straight: most homeowners panic when their garage door won't open or acts broken. But before you call for emergency service, there's solid troubleshooting you can do safely yourself. Here's what actually works and what signals you need a pro in Candia.
Start with the Obvious Checks
First, is the door actually stuck, or is something blocking the sensors? Walk the entire track on both sides. Look for leaves, ice, dirt, or debris jamming the rollers. In New Hampshire winters, frozen condensation builds up fast. A simple push or gentle clearing often fixes a door that seems broken.
Next, check your remote batteries. Sounds silly, but dead batteries account for maybe 20% of the calls we get. If the wall button works but the remote doesn't, swap in fresh batteries. If neither works, your garage door opener may have lost power. Check the outlet and the breaker.
Look at the photo eye sensors near the bottom of the door tracks. They're small, usually black or dark gray. If one is covered, dirty, or misaligned, the door won't close. Wipe both lenses clean with a soft cloth. Make sure nothing is blocking the beam between them.
When the Door Moves But Sounds Broken
A loud grinding noise, squeaking, or rattling usually means lubrication, not replacement. Spray silicone lubricant on the rollers, hinges, and track. Never use WD40 on garage doors; it attracts dust and gums things up. Silicone keeps things moving smooth and quiet.
If the door moves slowly or jerks, the springs might be losing tension. This is where you stop and call. Garage door springs are under extreme pressure. I've seen DIY attempts end badly. If you suspect a broken or weakening spring, read our guide on snapped garage door springs in Candia to understand the signs, then contact a professional.
Diagnosing a Door That Won't Open or Close
If the door won't open but the opener hums, the spring is likely broken. If it won't close and reverses halfway, the photo eye needs alignment or the spring is failing. If nothing happens when you press the button, power is cut somewhere.
Here's a quick diagnostic: press the wall button while watching the door. Does the opener engage at all? If yes, the motor works. The problem is mechanical. If no sound comes from the opener, check your breaker and outlet first.

When to Call a Professional
Don't attempt spring replacement yourself. Springs carry around 200 pounds of tension per side. A slip means serious injury. Same goes for cable work. These are the two parts that actually lift the door weight.
If you hear a loud bang or snap, a spring just broke. The door will feel much heavier. This is urgent but not dangerous if you don't try to force it. Our emergency garage door service page explains what happens when you call and how fast we can get there.
Bent tracks, damaged panels, and broken rollers also need professional hands. A bent track won't self-correct and will pull the door crooked, straining the entire system.
Getting an Estimate
When you do call, be ready to describe what's happening. "Won't open" is different from "opens halfway then stops." "Broken spring" is different from "making noise." The more detail you give, the faster we can diagnose and quote you.

Frequently Asked Questions
Why does my garage door open partway then close? Usually the photo eye sensors are misaligned or dirty, or the spring is weakening. Check sensor alignment first. If that's not it, call a pro before the spring fully breaks.
Can I lubricate the garage door myself? Yes. Use silicone spray on rollers, hinges, and tracks. Avoid WD40. Spray lightly and wipe excess. Do this every six months for smooth operation.
What's the most common garage door problem? Broken or weakening springs. They last about 7 to 9 years with typical use. After that, replacement is usually near.
How much does a garage door repair usually cost? Simple fixes like sensor cleaning or lubrication are free or under $50. Spring replacement runs $200 to $400. Cable work, $150 to $300. Get an estimate first.
Should I try to open my door manually if the opener fails? Only if the spring is intact. If the spring is broken, the door is extremely heavy. Trying to lift it risks pinched fingers or a falling door. Call for help instead.
