My Garage Door Opener Will Not Respond
Check two things before anything else: the safety sensors near the floor, and the red disconnect cord. Between them they cover most of the reasons an opener goes quiet. Navarro Garage Door repairs openers across Fremont, Newark and Union City, starting at $200. Open 24 hours, seven days a week. Call (510) 443-1883.
Right now
Do this before anyone arrives
-
Check the sensor lights
Both sensors near the floor should show a steady light. A dark or blinking one is out of line or blocked.
-
Check the red release cord
If it has been pulled, the opener runs without the door. Pull it again with the door fully closed to reconnect.
-
Try the wall button and the remote
Which one fails narrows the fault down.
-
Lift the door by hand
With the opener disconnected, a heavy door means the springs, not the opener.
How to tell
What the opener is doing
- The motor hums but the door doesn't move
- One click, then nothing at all
- The door starts to close then reverses back up
- The remote works but the wall button doesn't, or the reverse
- The opener runs but the door stays still
Why
What causes it
What the opener does tells you which part has gone. A hum with no movement is almost always the drive gear, a plastic gear driving a steel worm that is built to wear out before the motor does. A single click and then silence points to the logic board or the capacitor. A door that reverses before it closes is the safety sensors rather than the opener at all. An opener running while the door sits still means the carriage has been disconnected.
Do it yourself?
Where the line is
Sensor alignment and the release cord are both fair to check yourself, and often that is the whole fix. Anything inside the housing is different, because the capacitor in an opener holds a charge after the unit is unplugged.

Questions
Opener questions
How much does garage door opener repair cost?
Opener repair starts at $200. A drive gear kit is the simpler repair and a logic board costs more. A sensor realignment is quick and needs no parts.
Why does my garage door open but not close?
The safety sensors, nearly every time. The opener raises a door with a blocked or misaligned beam but refuses to lower it. The full sensor check is on the page for a door that won't close.
My opener hums but the door won't move. What is wrong?
The drive gear, in most cases. It's a plastic gear meant to fail before the motor does, so a hum with no movement usually means it has stripped. A gear kit is a routine repair and is well worth doing on an opener that is otherwise sound.
Is it worth repairing an old opener?
Under about ten years old, repair almost always makes sense. Past fifteen, once a logic board or a motor is involved, the repair gets close to the cost of a new unit with a battery backup and current safety hardware. You hear which one you have before you spend anything.
