REPAIRING A GARAGE DOOR THAT WILL OPEN BUT WONT CLOSE.
Automatic garage doors operate with a sensor. It is actually called a safety sensor with a reversing system. They normally come in a four to five inches over the garage floor. Usually when the sensor is faulty, the light bulb will flash many times in order for you to notice that there is a fault. The garage door will not shut unless there is pressure on the button mounted inside the garage. In order for you to start repairing your garage door that is stuck open and won’t close, check the following:
Clean any dirt, debris between the safety sensors. This can be debris from leaves, trash and dirt on the lens of the sensor itself. Check that your sensor for indicator for indicator lights, if they are on or if flickering or maybe out of alignment.
To check for misalignment; obstruct the beam of the sensors so that they cannot directly see each other. When the safety eyes is blocked, the indicator light on one of the two sensors will for a moment go out. This is probably receiving sensor. Discard the obstruction and loosen the bracket on the back of the receiving sensor. Adjust the receiving sensor until the indicator light goes out, if not already out, then realign until the green or red light is bright and steady, then refasten the sensor.
If an indicator light is not burning on one or both sensors, check for a possible loose or shorted wire. Sensor wires are attached to the white and black terminals on the back or side panel of the overhead motor unit. Confirm that they are firmly connected to each terminal. Also verify the wires for any breaks, specifically anywhere they are spliced together.
If the previous steps have been followed thoroughly and the conditions continue, there may be an electronic short in the wiring, safety eyes, or the receiver logic board. In this case, remove the safety eyes and temporarily wire them in the motor head unit with a lessened known unshorted set wire. If the symptoms continue after the eyes are removed, replace the computer board and or safety beams. If the symptoms cease with the safety eyes after using unshorted wires to the motor unit, replace all the wiring from the opener head to the safety sensor location 4 to 6 inches on top of the floor.
Following any adjustment to the sensors, the opener itself, or the garage door, the safety system must be tested:
1. Use the remote control push button to raise the garage door.
2. Set a box or similar object in the path of the door.
3. Press the remote control push button to close the door. The door should not move more than one inch, and the opener lights shall flash.
WARNING: Without a properly installed safety reversal device, people (particularly small children) can be seriously injured or death by a shutting garage door. If the electric opener closes the door when the safety-reversing sensor is obstructed (and the sensors are no more than 6 inches on top of the floor), call for a trained door systems technician.
