Your garage door opener stopped working. Maybe it makes no sound at all. Maybe it runs but the door does not move. Maybe the remote stopped responding but the wall button still works — or neither one does anything.
Opener problems are one of the most common service calls we handle in Manassas Park and nearby areas. The good news is that many of them come down to simple causes that can be identified quickly. The bad news is that some causes are more serious and require a professional to fix safely.
This guide walks you through the most common opener problems in order — from the simplest fixes you can try yourself to the situations that need a technician.
Teo Garage Doors diagnoses and repairs garage door openers in Manassas Park and nearby areas. Call 571-505-8443 for same-day service.
Why is my garage door opener not working? A garage door opener may stop working due to dead remote batteries, a tripped circuit breaker, a disconnected trolley, misaligned safety sensors, or a failed motor or logic board. Start with the simplest causes first before assuming a major failure. If the opener runs but the door does not move, a broken spring is the most likely cause. Call Teo Garage Doors at 571-505-8443 for same-day diagnosis in Manassas Park and nearby areas.

Step 1 — Check the Power Supply
Before anything else, confirm the opener has power. This sounds obvious but it is the cause of more service calls than you would expect.
Check the Outlet
The opener plugs into a standard outlet on the garage ceiling. Make sure it is fully plugged in. Test the outlet by plugging in another device — a phone charger or a lamp. If the outlet has no power, the opener will not respond to anything.
Check the Circuit Breaker
If the outlet has no power, go to your home’s electrical panel and look for a tripped breaker. A tripped breaker sits in the middle position — neither fully on nor fully off. Reset it by switching it fully off and then back on. Return to the garage and test the outlet again.
Check the GFCI Outlet
In some garages the opener outlet is connected to a GFCI outlet — the type with the test and reset buttons — located nearby. If that GFCI has tripped, it will cut power to any outlets on the same circuit, including the opener. Find the GFCI outlet and press the reset button.
If power is restored and the opener still does not respond, move to the next step.
Step 2 — Check the Remote
If the wall button works but the remote does not, the problem is the remote — not the opener.
Replace the Batteries
Dead or weak batteries are the most common cause of a remote that stops working. Most garage door remotes use standard AA or AAA batteries. Replace them with fresh batteries and test the remote again. Try pressing the button while standing closer to the opener if the signal seems weak.
Reprogram the Remote
If new batteries do not fix the problem, the remote may have lost its programming. Most openers have a learn button on the motor unit — pressing it and then pressing the remote button within 30 seconds should reprogram the connection. Refer to your opener’s manual for the exact steps, or call Teo Garage Doors at 571-505-8443 and we can walk you through the process for your specific model.
Replace the Remote
If reprogramming does not work, the remote itself may be faulty. Replacement remotes are available for all major opener brands. Our technicians carry common replacement remotes and can program them on the spot during a service visit.
Step 3 — Check the Safety Sensors
If neither the remote nor the wall button will close the door — or if the opener runs briefly and then reverses — the safety sensors are the most likely cause.
How the Sensors Work
Two sensors sit near the floor on each side of the door, one on each track. They send an invisible beam across the opening. If that beam is interrupted or if the sensors are misaligned, the opener will not allow the door to close and may refuse to open fully as well.
How to Identify a Sensor Problem
Look at the indicator lights on each sensor unit. Under normal operation, both lights should be solid — typically one green and one amber. If either light is off, blinking, or both are the same color when they should not be, a sensor issue is present.
What to Do
Check for any object blocking the sensor path — even a small piece of debris, a leaf, or a cobweb can trigger the safety system. Wipe both sensor lenses clean with a dry cloth. If the sensors appear to be knocked out of alignment, carefully adjust them until both indicator lights are solid and steady. Test the door again.
If the lights are solid but the opener still behaves erratically, the sensor wiring may be damaged or the sensors themselves may need to be replaced. Call Teo Garage Doors for a diagnosis.
Step 4 — Check the Trolley
The trolley is the moving carriage on the opener rail that physically connects the motor to the door. Every opener has a red emergency release cord hanging from the trolley — designed to allow manual operation during a power outage.
If that cord was pulled at some point, the trolley is now disconnected from the door. The opener will run through its full cycle and sound completely normal, but the door will not move.
How to Tell If the Trolley Is Disconnected
Press the wall button and watch the trolley on the rail. If it moves back and forth smoothly but the door does not move with it, the trolley is disconnected.
How to Reconnect It
Pull the red cord toward the door at an angle — not straight down. You should hear or feel a click as the carriage re-engages. Then press the wall button to run the opener through a full cycle. The door should reconnect and move normally.
If the trolley is broken rather than just disconnected, a technician will need to replace the carriage assembly.
Step 5 — Check the Springs
This is the step most homeowners miss — and it is one of the most important.
If the opener runs, sounds normal, and the trolley is connected and moving — but the door still does not move — the problem is almost certainly not the opener at all. It is the spring.
Garage door springs counterbalance the full weight of the door. When a spring breaks, the door becomes too heavy for the opener to lift. The opener tries, detects the resistance, and stops — usually after a few inches or immediately.
How to Check
Look up at the spring above the door. On a torsion spring system you will see a horizontal coil running along a metal bar. If the spring is broken, there will be a visible gap or separation in the coil.
If you suspect a broken spring, stop using the door immediately. Do not attempt to open it manually. Call Teo Garage Doors at 571-505-8443 for emergency spring replacement — available same-day in Manassas Park and nearby areas.

Step 6 — Opener Motor or Logic Board Failure
If you have worked through all the steps above and the opener still does not function correctly, the problem is internal to the opener unit itself.
Motor Failure
The motor that drives the opener wears out over time. Signs of motor failure include the opener making grinding or humming sounds without moving, running very briefly and then stopping, or producing no sound at all when the button is pressed.
Logic Board Failure
The logic board is the circuit board inside the opener that controls its operation. A power surge can damage the board even if the surge was brief. Signs of a logic board failure include erratic behavior — the opener responding inconsistently, running at the wrong times, or not responding at all — even when everything else checks out.
In some cases the logic board can be replaced without replacing the full opener. In others — particularly on older units — it makes more sense to invest in a new opener with modern features rather than repair an aging one.
Teo Garage Doors diagnoses and repairs all major opener brands including LiftMaster, Chamberlain, Genie, and Craftsman. We carry common replacement parts and can complete most opener repairs in a single visit.
Should I repair or replace my garage door opener? If the opener is less than 10 years old and the failure is an isolated component — a logic board, a drive gear, or a broken belt — repair is usually the right call. If the opener is more than 10 to 15 years old and experiencing multiple issues, replacement is often the better investment. Teo Garage Doors will give you an honest recommendation after a free diagnosis. Call 571-505-8443.
When to Call a Professional
You can safely handle the following without professional help: replacing remote batteries, resetting a tripped breaker, pressing a GFCI reset button, clearing sensor obstructions, and reconnecting a disconnected trolley.
You should always call a professional for: broken or suspected broken springs, broken cables, motor or logic board diagnosis and replacement, sensor wiring issues, and any situation where the door feels heavier than usual or moves unevenly.
Attempting to work on springs or cables without the proper tools and training is genuinely dangerous. These components are under significant tension and can cause serious injury.

Frequently Asked Questions
Why does my garage door opener run but the door won’t move? If the opener runs but the door does not move, the most likely cause is a broken spring. The spring counterbalances the weight of the door and when it breaks, the opener cannot lift the door. It can also be caused by a disconnected trolley. Stop using the door and call Teo Garage Doors at 571-505-8443.
Why does my garage door opener work sometimes and not others? Intermittent opener problems are often caused by weak remote batteries, interference from another device on the same frequency, or a failing logic board. If the problem is getting worse over time, call Teo Garage Doors for a diagnosis before the opener fails completely.
Why won’t my garage door close but it opens fine? A door that opens but will not close is almost always a sensor issue. The safety sensors are detecting a real or perceived obstruction and preventing the door from closing. Check for debris blocking the sensor path, clean the lenses, and make sure both indicator lights are solid. If the problem continues, call Teo Garage Doors at 571-505-8443.
How long do garage door openers last? Most garage door openers last between 10 and 15 years with normal use. Openers that are used heavily — more than four or five cycles per day — may reach the end of their life sooner. If your opener is more than 10 years old and starting to show problems, it may be worth considering a replacement before it fails completely.
Does Teo Garage Doors install new garage door openers? Yes. Teo Garage Doors installs all major opener brands including LiftMaster, Chamberlain, Genie, and Craftsman. We also install smart openers with WiFi connectivity and battery backup for homes that experience frequent power outages. Call 571-505-8443 for a recommendation and free estimate.
How much does garage door opener repair cost in Manassas Park? The cost depends on what has failed. Minor repairs such as a logic board or drive gear replacement cost less than a full opener replacement. Teo Garage Doors provides a full upfront quote before any work begins.
