Start With What the Door Did
The most useful clue is the moment it stopped working. A loud bang followed by a dead door points one way. A door that has been getting slower and noisier for weeks points another. A door that does nothing at all when you press the button, with no sound from the motor, points at power or controls. Before checking anything, try to remember exactly what happened, because that is the first question any technician will ask.
Nothing Happens at All
If the opener is completely silent, start with power. Storm season brings flickers and outages across the area, and an opener on a tripped breaker or a GFCI outlet that has cut out will show no sign of life. Check whether the light on the motor head comes on, and whether other outlets in the garage are working. A tripped breaker is worth resetting once; if it trips again, stop and have it looked at rather than resetting repeatedly.
If the wall button works but the remotes do not, the opener is fine and the problem is in the remotes: batteries first, then programming. If the remotes work and the wall button does not, the wiring to the wall station is the likely culprit. Either way the door itself is not at fault.
The Motor Runs but the Door Stays Put
This is the classic broken-spring signature, especially when it follows a bang you heard from inside the house. The opener is running, the chain or belt may be moving, but the door does not lift because the springs that carry its weight have failed. From a safe distance, look above the opening for a gap in the coiled spring, or along the tracks for a stretched spring hanging loose.
The other version of this is a stripped drive gear. The motor sounds like it is working, sometimes with a grinding note, but nothing is transmitted to the trolley. Both faults have the same instruction attached: stop pressing the button. Running an opener against a door it cannot lift adds a second repair to the first.
The Door Starts and Stops
A door that lifts a few inches and drops back, or starts down and reverses, is usually responding to a safety system doing its job. The photo eyes near the floor are the first suspect: a bracket knocked by a bicycle, a fogged lens, a spider web across the beam or a corroded wire at the staple will all interrupt them. Most openers show a blinking light pattern when the sensors are unhappy.
Binding hardware creates the same symptom. If a roller has seized or the door is catching at the same point every time, the opener senses the resistance and stops. That is a mechanical fault, not an electronic one, and forcing it with a higher force setting is exactly the wrong response.
The Door Is Crooked or Jammed
If one side of the door is sitting lower than the other, or a roller has come out of its track, stop using the door entirely. A cable has probably slipped off its drum, and the door is no longer supported evenly. Keep vehicles and people out of the opening and do not pull the emergency release, because a door held in an unbalanced position can move suddenly once the opener lets go of it.
What Is Safe to Check Yourself
From outside the door's path you can safely check the breaker, the outlet, the remote batteries, whether anything is blocking the photo eyes, and whether the lock or slide bolt on the door has been thrown. That is the full list. Springs, cables, drums and the shaft above the door are all under load and are not homeowner-serviceable, no matter how straightforward a video makes it look.
Garage Doors in the Katy Area
Two local factors show up in these calls repeatedly. Wide double doors are standard here, so when a spring lets go there is a lot of weight sitting on the opener. And because garages stay closed and humid for most of the day, corroded cables and seized rollers are a common reason a door binds rather than lifting cleanly. Households in Cypress and similar commuter neighborhoods also cycle their doors many times a day, which brings spring failures forward.
Arrange an Inspection
If the door will not open and a car is trapped inside, say so when you call so the visit can be prioritized. Katy Garage Door Service diagnoses the fault at the property and quotes before any work begins. Read about spring repair, opener repair or cable and roller repair, and request a service visit when you are ready.
