Garage Door Closes Then Reopens
in Overland Park, KS
A door that reverses before it closes all the way is working as designed, but something is triggering the safety reversal that shouldn't be. This is a frequent issue in homes in the Prairie Village and Overland Park border areas where attached garages are used for storage and the sensor area gets crowded. In some cases the close-force setting on the opener needs adjustment, especially if the door or opener is older than 15 years.
Quick Answer
When a garage door closes partway and then reverses, it is usually responding to a sensor problem or incorrect close-force settings in the opener. Overland Park homes with attached garages tend to accumulate clutter near the sensor eyes over time, and something as small as a leaf or a spiderweb can trigger the reversal. A technician can clear the sensor path and recalibrate the opener settings. Call (913) 901-9954 if clearing the sensors doesn't solve it.
Telltale Signs
Warning Signs to Watch For
- The door closes most of the way and then opens back up without being touched
- The opener light flashes a set number of times after the reversal
- The door reverses at the same point in its travel every time
- The door closes fine when you hold the wall button the whole time but reverses on auto-close
- One of the sensor lights near the floor is off or flickering
Root Causes
What Causes Garage Door Closes Then Reopens?
Blocked or Misaligned Safety Sensors
The two sensors near the floor send a beam across the door opening. Anything that breaks the beam, including a box, a garden hose, or even a spiderweb, tells the opener to reverse. Sensors also drift out of alignment slowly, especially in garages where the floor has shifted on clay soil.
The Fix
Sensor Clearing and Realignment
The sensor path is cleared of obstructions and each sensor bracket is adjusted until both lights show solid. If a sensor lens is cracked or the wiring is damaged, the sensor is replaced.
Close-Force Setting Too Sensitive
Garage door openers have a close-force adjustment that tells the motor how hard to push before deciding it hit an obstacle and reversing. On openers more than 10 years old in Overland Park homes, these settings drift or were never calibrated correctly after a spring replacement.
The Fix
Close-Force Recalibration
The technician adjusts the close-force dial or setting on the opener until the door closes fully on a flat floor without reversing unnecessarily. The setting is tested several times to make sure it is not so high that it would fail to reverse if someone or something were actually in the way.
Damaged or Uneven Bottom Seal Catching on Floor
If the rubber bottom seal has a torn section that folds under the door, the opener senses the extra resistance and reverses to avoid crushing an obstacle. This is more likely on doors where the slab has settled unevenly, which is common on Overland Park properties built before 1990.
The Fix
Bottom Seal Replacement
The old seal is removed and a new one is installed that sits flat against the floor without bunching or folding. Once the extra resistance is gone, the opener usually closes normally without needing a force adjustment.
