Garage Door Won’t Close in Santa Monica, CA
A door that refuses to close can be reacting to a safety sensor, obstruction, travel setting, opener fault or mechanical resistance. Start by observing the symptom without bypassing safety features.
Common reasons a garage door will not close
When the door starts down and reverses, the opener may be detecting an obstruction or excessive resistance. Misaligned safety sensors can also prevent normal closing. A door that binds or sits crooked can create similar symptoms.
Clues worth noting
- The opener lights blink or the motor clicks.
- The door starts down, then reverses.
- The door will not move at all from the wall control or remote.
- The door closes only while a control is held, suggesting a safety/control issue.
- The door rubs, binds or looks uneven during travel.
Safe checks before service
Keep the doorway clear of people and objects. From a safe position, look at the two safety-sensor areas near the bottom of the tracks and note whether anything obviously blocks the beam. Do not bypass the sensors or continue testing a door that is visibly damaged or off track.
When a closing problem points to the door hardware
If the door is crooked, unusually heavy, noisy or rubbing the track, the opener may not be the root cause. Springs, cables, rollers and tracks all affect how much force the opener needs to move the door. A useful diagnosis considers the complete system.
Questions about a garage door that won’t close
Why does my garage door close and then reopen?
Sensors, travel settings, an obstruction or mechanical resistance can cause reversing. Keep the path clear and do not bypass safety features.
Can dirty sensors cause a closing problem?
They can. Obstruction or alignment issues around the safety sensors can stop normal closing.
Why will the door close only while I hold the button?
Some opener systems use that behavior when a safety or sensor condition needs attention. Have the system assessed rather than bypassing the safety feature.
Could a broken spring cause closing problems?
Yes. A counterbalance or mechanical problem can affect travel and load on the opener.
